[osg-users] CompositeViewer and osgViewer::ScreenCaptureHandler

[ted morris]

I have 4 osgViewer::View's I want to grab and save an image from each.
I tried to use osgViewer::ScreenCaptureHandler as part of the composite
view but only one view is captured. Then I tried to addEventHandler() to
each individual view
to test capturing one at a time but it only captured one camera/window with
the same view even if the mouse focus is switched from one view to another.
In the latter case, I even tried creating
4 separate ScreenCaptureHandler's to addEventHandler() to each
osgViewer::View.

Can someone suggest how and if osgViewer::ScreenCaptureHandler can be used
in this way?

thanks very much!

Re: [osg-users] Advise on SLI dual quad buffered stereo display

[Ted Morris]

Hi Robert,

to answer your question I want to drive 4 stereoscopic displays in CAVE-like 
environment with  active shutter glasses (frame sync hardware will be required).

I haven't set up anything yet, but I plan on buying HW in the next few weeks. 
:-) I had found a very old thread, Oct 7 2010, "subj:OSG seems to have a 
problem scaling to multiple windows on multiple graphics cards", but the 
landscape of HW,drivers, and OSG has changed quite a bit since then.


... 

Thanks,

Ted

[osg-users] Advise on SLI dual quad buffered stereo display

[ted morris]

I am considering two options for a high performance multi-screen 3D stereo
rendering
engine (2 high res). One option is a cluster of 2 machines with separate
cards + Famesync
 (quad buffering). The second is of course combining and using SLI to drive
two separate
displays, which will be more cost effective and simpler to manage. I am
thinking of going  with Maxwell Quadro M5000's

Before I went head long into this latter option, would anyone like to share
advise/experience for general OSG window/viewport configuration? I can work
with Linux or Windows...

Re: [osg-users] CompositeViewer Node render order problem Win32 osg 3.4

[ted morris]

Hello Robert,

The thread is getting a little stale but shall I say not forgotten if gone.
;-y

I wanted to only reply that the problem was due to the osg::camera as
declared within my method from the code above as:

// create a camera to set up the projection and model view matrices, and
the subgraph to drawn in the HUD
osg::Camera* camera = new osg::Camera;

simply needed to be declared on the heap as a member of the class and all
worked perfectly fine there after.

As a final note: I also changed the code to use osgViewer::View for the
osgViewer::CompositeViewer
as well-- thanks very much for that guidance. All the Views were already
declared as members of my class.

[osg-users] CompositeViewer Node render order problem Win32 osg 3.4

[ted morris]

Greetings OSG'ers.

I have a program which utilizes CompositeViewer to render a "corner window"
view of my scene graph, within a bigger main window view. To achieve a
boarder effect around the corner window viewport, a HUD overlay used to
render a grey box underneath the 2nd view corner window.

It worked without a hitch  in an older version, 2.8.5 win32 of
OpenSceneGraph (build with VisualStudio).

But when I recompiled the program with a later built version (CMake.exe/VS
2013), I get rather strange object rendering order problems with the
objects in the same scene graph with the **2nd, corner window**  of the
osgCompositeViewer.  The **first main window** renders perfectly fine. The
essence of the code is below. A lot of extra code  is used for determining
the appropriate window and HUD boarder 'frame' dimensions and camera view
frustums, but barring that,  it is pretty straight forward and not much to
it, I think.

To simplify the code a little bit for brevity, I have the removed Trackball
code because with much testing on various configurations this doesn't
change the observed behavior anyway (nor does any lighting mode).

I did try clone(osg::CopyOp::SHALLOW_COPY) of the entire scene graph model,
and even re-creating parts ofit from scratch and the same
strange rendering order behavior resulted.

Any advice or insights would be greatly appreciated,

thanks all,

ted

[osg-users] strange behavior

[ted morris]

hi, I am using 3.4.0 with VisualStudio 2013, Win 8.1/x64, which all built
fine (examples all work as expected).

So, I wrote  a very simple program, which unfortunately renders the cube
offset from the horizontal axis, instead of being centered. The bounding
sphere center = 0,0,0.  If I instead add:

view1.setUpViewInWindow(0, 0, image_width, image_height);

then it renders as expected at the center of the window with the default
node trackball camera manipulator.

 Would anyone have a clue why am I observing this behavior and how to
correct the problem?

Greetings,

I'm using osgDB::readNodeFile(m_ply_filename) in a keyboard event handler
to update
a scenegraph node. What is the best way to update the scenegraph to display
this data in the osg::viewer?

The group and the child node underneath it are in scope (I checked) but the
scenegraph isn't
updating with the new data. I also see that bounding properties are
updating as well.

thanks for any tips or advice,

Re: [osg-users] Kinect

[ted morris]

Hi Chris,

I think your plot is misrepresenting the appropriate feature space for this
analysis. You are
missing estimated component angles of each ray extending from the image
plane to the surface
target + angle of incidence. I would simplify the scene substantially; why
not take a
flat surface (a piece of foam board with know dimensions) and place it in an
open space at a
few known distances from the sensor?

You can then also rotate the image plane about a couple estimated angles.
Then plot errors perhaps
as a function of distance vs. sqrt( angle_x^2 + angle_y^2), as a start.  I
would recommend that you take
a look at a paper:

Anderson, D., Herman, H., Kelly A., Experimental Characterization of
Commercial Flash Ladar Devices,
International Conference On Sensing, 2005.

Yes, it is different technology but the error analysis used there I think
would be relevant.

cheers,
t

 Hi Tedzini,

 I'm not very familiar with CIGI, but it seem to be a communication library
 for communication with the sim-host.

 I'm quite sure you can use CIGI not only for managing the camera but also
 for managing objects you want to display.

 Currently osgVisuals cluster module is used to transport objects or
 camera modifications from the master to all slaves, but maybe that UDP
 implementation could be replaced by CIGI - it mainly depends on the
 performance.

[ted morris]

this indeed has caught my eye as well. But I am not familiar with the CIGI
standard.
Would this include the ability to manage object motions and
behaviors across the
cluster? (e.g., not only camera positioning).

thnx,

 Torben,

 Thanks for the information. I ask this because I'm currently working on
 doing a CIGI tie-in to an OSG-based IG backend I've been developing. I'm
 not
 a proponent for reinventing the wheel so to speak so I'm always on the
 lookout for other options in this regard.

 osgVisual would be something I would seriously consider using if it
 supported CIGI. Unfortunately our hosts talk CIGI so we need this support.

 By way of interest, I have found another OSG-based IG solution called
 SubrScene that does talk CIGI but it appears to be using a pretty old
 version of OSG. I'm not sure it's OpenSource so updating it to the current
 OSG might not be an option. SubrScene is included with the distribution of
 OpenEaagles which is OpenSource.

 I will still play with osgVisual to see what it has to offer...:)

 Hi S2LR,

 Yes, there were plans to create a CIGI implementation of extLink.
 Unfortunately for more than one year the project is not funded so all
 developments are competetive to my job. Therefore I can't spend as many
 hours as I would like to and CIGI support ist not on top of my todo stack..

 But I would like to support any development in the direction of CIGI! It
 would be an improvement because currently only my proprietary extLink
 implementation is available.

 Thank you!

[osg-users] [build] osglogo link failed with Xcode 3.2, osg2.8.3, MAC OSX 10.6

[Ted Morris]

Hi,

From a previous post regarding unresolved externals, I decided to mimic as 
close as possible how one of the examples were built from the 
openscenegraph.xcode project. In this case, I tried two methods. 

First, I built the Xcode project from scratch, including the various 
frameworks, and macro defs, etc. In the second, instead of the osglogo app, I 
started with the osg template. I made sure that the frameworks were referenced 
to the OpenSceneGraph 2.8.3 carbon 32 bit release frameworks.

In Either cases, everything compiles correctly but I still get this error:

snip
Undefined symbols:
  OpenThreads::Atomic::operator--(), referenced from:
  osg::Referenced::unref() constin main.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
snip

The generated link line, building for 32bit i386, for the 2nd template test 
contains the OpenThreads framework (and it is in the same dir as the other osg 
Frameworks), as shown below:

The osglogo.cpp code produces the same result, and therefore I don't repeat it. 
I know the frameworks and plugins built correctly because all the example and 
executable apps compiled and bundled successfully. Has anyone come across a 
similar problem like this?  I've stared and plated with various linker and 
compile flags and I'm stumped. 

Thank you!

[osg-users] [build] app unresolved link errors: carbon 32bit OpenThreads.framework on MAC OSX 10.6.5

[Ted Morris]

Hi,

This is driving me mad. I didn't have this problem when I built 64bit cocoa, 
but I had to backstep to carbon due to some issues with wxWindow 2.9.1 cocoa 
64bit compatibility issues at the moment.6

I get the following unresolved OpenThreads link error with GCC 4.2/Xcode 3.2, 
running OSX 10.6.5. 

snip

The Xcode 3.2 compile command, which is rather thick since it includes static

I build osg (and tested the various built apps to make sure they work) with the 
32bit carbon; both release and debug. The 32bit carbon release 
OpenThreads.framework directory looks like this:

snip


Anyone have any insights or advise? Again the osg example apps, etc. work fine. 
So, my guess is that

[Ted Morris]

ps: a follow up reply--

I should've mentioned I took out OpenThreads framework and I got the same 
errors. just can't figure out why the link won't recognize the 
OpenThreads.framework


Thank you!

[osg-users] imageio pluggin, MACOSX 10.6, x86_64bit build question

[Ted Morris]

Hi,

I would like to know why the imageio pluggin .so wasn't invoked for jpg/png 
images with my cocoa/x64 bit build of osg on MACOSX 10.6. For example, running 
some of the osg examples indicates that it was unable to load the images 
(although they were correctly found).  Could it be the .png or .jpg extensions 
are forcing osg to look for the associated image pluggins?

How is this supposed to be invoked, at least when running the apps from the 
command line?



Thanks for any help-

Cheers,
Ted

Re: [osg-users] OSX .app bundle internal dir path rules?

Hi Len,

so is that the actual name of the folder @executable_path within the App 
bundle, or are you inferring that is to be substituted with the actual exec path
where the binary is, e.g.,  @MacOS, is s etc.?

Just want to make sure I understand--

   - cow.osg
   + aSampleFolder

You can use the copy-files build-phase of xcode to copy the various
files to their correct locations.

So, to get the path to cow.osg, all you need to do is:

{
   std::string file = osgDB::findDataFile(cow.osg);
   osg::Node* node = osgDB::readNodeFile(file);
}

{
   std::string file = osgDB::findDataFile(aSampleFolder/dumptruck.osg);
   osg::Node* node = osgDB::readNodeFile(file);
}

[osg-users] OSX .app bundle internal dir path rules?

[Ted Morris]

greetings,

I'm very new to MAC platforms. I'm in the process of porting an osg-based app 
to the mac and before I go too far with creating new 'default' search paths for 
required data, I would like to know if anyone can supply any insights to the 
actual path rules to the internal app bundle directories. For example, suppose 
I have a couple of databases that are needed by the app. what 'path' does the 
resources folder represent? e.g., if I want them under a sub-directory -- 
e.g., Scenes, would the 'default' path for my app be ./Scenes ? 

I'm just not clear how the various directories hidden in the app bundle are 
referenced by 1) code in general, 2) the osg image and database pluggins.

Thanks in advance for advice!

Cheers,
Ted

[osg-users] MAC OS-X advise with OSG

[Ted Morris]

Hi,

I'm a complete newbie with Macs, but I am charged with the task of porting some 
apps that ran on Win32/64 on the Mac.  In addition, the application lets 
students create their own dlls that are then opened interactively to test 
simulation solutions and visualize results. 

I looked at some tutorials for bundling OSG apps with Xcode. My issue is that 
after I downloaded Xcode it wants MAC OS X 10.6.4 (Snow Leopard) which this 
(new! MacBook Pro i5) laptop even after the update is still 10.5!. I am 
beginning to wonder if I am better off going with gnu tools instead?  Should I 
worry about OSG apps and dylibs compiled/linked on the later OS not running on 
earlier MAC OS -X versions?


Thanks for any advice in advance.

Re: [osg-users] Intel GMA giving me fits with OSG 2.8.2

[ted morris]

Hi Chris,

The version I have been using is 8.15.10.2202 (8/25/2010) on Win7 6.1.7600
Home Premium.

Actually, that was the latest from Micro$oft's updater but I just installed
8.15.10.2226 (10/28/2010) off the Intel driver support. I haven't had a
chance to reboot (being occupied at the moment; my son can't use the 'dad
ate my homework' excuse tonight).

It came pre-installed with 'Intel Control Center' which had settings to
force v-synch, and enable-software-vertex update, but when I run stats I was
still getting crazy frame rates.
Something definitely is not right with the drivers. ...

thnx,
t

  Are you 100% sure you're using a current Intel GMA driver? What exact
 driver version do
 you have, and what OS is it under?

[osg-users] Intel GMA giving me fits with OSG 2.8.2

[Ted Morris]

Hi,

I'm using the 'stable' package binaries for WinXP/Vista/7.

I noticed a very interesting but problematic  'querk'. ? I have a fairly
simple model (essentially a truck cab model that came with Multigen quite a few 
years back -- genesis I'm sure early 3.x days...). It renders just fine 
(osgviewer.exe) on every machine I've tried *except* my ASUS Win7 laptop that 
has an Intel GMA chipset for rendering. With this, the polygons get completely 
mangled; it looks as though the model went through a 'random Chaos machine' of 
sorts.  

 I installed the latest drivers to no avail. I'm not sure what else I should 
do. Has anyone run accross similar problems with OSG running Windows 7 and 
Intel GMA running on an ASUS laptop?

I've attached the model if anyone wants to try it.

Thanks in advance for any tips/advise.

Cheers,
Ted

 Hi Ted,

 A shallow copy will share as much as possible of the data below the
 object you are calling clone on.  Only a deep copy will force the data
 itself to be copied.

 As a general note, you want to avoid duplicating data as much as
 possible, so share as much as possible.  In you case it might not be
 necessary to clone anything and share the whole scene graph between
 views.  You can use a combination of NodeMask and Camera CullMask
 (see osg::CullSetting from which osg::Camera is derived), to enable
 each view to just see a portion of the scene.

[osg-users] problem with hud overlay

[Ted Morris]

Hi,

I thought this would be extremely trivial. But, perhaps I am missing something. 
I have a HUD ortho2D camera slaved to a main view window camera, rendering a 
polygon. I need to move the polygon when I resize the main window, which I 
attempted by simply placing the geode underneath a MatrixTransform node, first 
setting it to identity() and placing it under the HUD camera. However, when I 
did this, the polygon no longer is rendered in the window at all. 

Note that everything renders fine with a Geode before I placed it under the 
MatrixTransform. 

To recap this is essentially what I tried:

m_HUDcam = new osg::Camera;

 m_HUDcam-setProjectionMatrix( osg::Matrix::ortho2D(0,   
m_viewersize.GetX(),0, m_viewersize.GetY()));

m_HUDcam-setReferenceFrame(osg::Transform::ABSOLUTE_RF);

m_HUDcam-setClearMask(GL_DEPTH_BUFFER_BIT);

// draw subgraph after main camera view.

m_HUDcam-setRenderOrder(osg::Camera::POST_RENDER,0);

m_HUDcam-setAllowEventFocus(false);

// create the frame

osg::MatrixTransform * matrixtransfm = new osg::MatrixTransform;
matrixtransfm-setMatrix(osg::Matrix::identity());

// create the Geode (Geometry Node) to contain all our  osg::Geometry 
objects.
osg::Geode* geode = new osg::Geode();
osg::StateSet* stateset = geode-getOrCreateStateSet();
 stateset-setMode(GL_LIGHTING,osg::StateAttribute::OFF);
matrixtransfm-setChild(0, geode);

  //  construct the polygon(s) primitive(s) here ...
  
 // attach it to the HUD camera -- now the polygon(s) don't display.
 m_HUDcam-addChild(matrixtransfm);

 // but uncommenting this out, and polygon displays :
 // m_HUDcam-addChild(geode);

 // viewport, etc.
 m_HUDcam-setViewport(  0 ,0, m_viewersize.GetX(),   
m_viewersize.GetY());

 m_HUDcam-setGraphicsContext(gw);

 m_viewer-addSlave(m_HUDcam, false);

 

 

Thank you!

Cheers,
Ted

[osg-users] previous post: Implementing a corner window within a single main osgviewer canvas

[Ted Morris]

Hi,

snip
Posted: Sun Oct 17, 2010 9:20 pmPost subject: Implementing a corner 
window within a single main osgviewer canvas. I see two replies but for some 
reason, I can't see the responses (I'm ahead of the game?). Sorry for the 
trouble.:-* 
snip

I would like to add a corner window within the main window, rendering 
part of my scenegraph. I've been thinking about using osghud to accomplish this 
task. But, before I delve into this any further, I would like to ask the group 
if another approach would be better. The osgviewer canvas is resizable, but I 
think I would keep the corner window the same size. 
Also, I'm only going to have the camera follow the object; I don't think 
handling mouse/keyboard events will be desired. 

I use wxWindows 2.9.x for developing the app.

okay... but I wonder why the other callbacks for the other osg::Switch

get their updateCallbacks invoked.  Perhaps I'll have to try and explicitly
removed the updateCallbacks

 fine. But then it also is still running through object 0 callback
 (although it is not being rendered in the scene). Interestingly, the other
 children  1 don't have their callbacks invoked under this circumstance.


 The UpdateVisitor constructor shows that it uses the TRAVERSE_ALL_CHILDREN
 traversal mode by default, so it doesn't necessarily care which child is
 active. If a subgraph contains update callbacks, the UpdateVisitor will
 traverse.

 I think the OSG Quick Start Guide uses a PolytopeIntersector to demonstrate
 picking.  Not exactly what you're trying to do, but it at least shows how to
 set up the intersector.  That's the only other example I know of.

[osg-users] osg::Switch , UpdateCallback not being dissabled

[Ted Morris]

Greetings,

A fairly simple question. 
I could be missing something really obvious here.

I have a switch node with a bunch of MatrixTransform objects
hung under it, all assigned to a particular update callback. Pretty
straight forward stuff, conceptually anyway.

OK, so I turn on one vehicle as in:

_vehiclesw-setSingleChildOn(1);

The scene just renders the single object and runs through the callback.
fine. But then it also is still running through object 0 callback (although 
it is not being rendered in the scene). Interestingly, the other children  1 
don't have their callbacks invoked under this circumstance.

Am I misunderstanding something about the class usage?

thanks for any tips/advice in advance,

Ted

 How do I detect whether the entire cube falls inside the pyramid or not?

 What if the cube is very small and can be defined by a single point 13.
 Can I find out if the point 13 falls within the pyramid with a simple osg

 I think you should be able to do this with a PolytopeIntersector.  Just add
 each face of the pyramid as a plane in the Polytope, and intersect it
 against the cube.
 The nice thing about the PolytopeIntersector is that it will work with
 points and lines as well as faces, so it should work for your second case.

Re: [osg-users] Vicon tracking

[ted morris]

On Wed, Mar 3, 2010 at 10:56 AM, Mel Av melinos...@hotmail.com wrote:

 Hey all,

 Many thanks for your answers.
 The Vicon system uses a z-up coordinate system, with millimeter units. It
 sends x,y,z coordinates for a given tracked object(in that case the cap you
 are wearing) as well as rotation information in axis/angle form. The client
 I'm using converts this to three different forms I can use interchangeably:
 1. Euler angles
 2. Global rotation matrix
 3. Quaternion

 Right now I am just using the viewer-getCamera()-setViewMatrix() call
 before the viewer.frame() call. The problem seems to be that the matrix I
 pass to setViewMatrix() does not seem to be correct. I use the x,y,z
 coordinates for the cap to set the translation matrix ( tr.makeTranslate() )
 and the quaternion to set the rotation matrix ( rot.makeRotate() ). I then
 multiply tr * rot and pass this to setViewMatrix(). The result is that when
 I move closer to the projected image, the rendered objects seems to come
 closer, which is correct behavior, but when i rotate my head this causes the
 rendered objects to rotate in the opposite direction. The code I use is from
 the OSG Quick start guide and it was supposed to change the view according
 to its description. However this does not seem to be the case for two
 reasons, from what I found out last night reading one old camera tutorial:
 1. You have to inverse the tr*rot result first
 2. After you do that, you have to rotate -90 degrees about the x-axis
 because Matrix classes use a Y-up coordinate frame whereas the viewer uses a
 Z-up coordinate frame.

 Will these two corrections solve the problem? Will I also need to do
 something more advanced like dynamically changing the frustum according to
 the head position?


yup, you will need to re-compute the proper frustum dynamically.  To do
that,  you will need to know the position/orientation of sensor coordinate
system is w.r.t. the 'window'.
Then you need to transform where your head is with respect to the window.
Finally you will need to know where your 'window' (what you see the world
through)
is w.r.t. your model world  coordinate system.  And of course you will need
to know this for the left/right eye positions. Doing a good job to solve for
these transformations
might take you a little thought/time depending on your set up. But, as it
seems like you have figured out as much, you can see that it can all be
realized pretty
easily with OSG matrix objects once you obtain the needed transformations.

Sometimes, as you start to chain your transformations together, it might
make things easier to
break it down into smaller steps and test out what you see. With so many
different conventions, etc...





 Thank you!

 Cheers,
 Mel

 P.S Sorry if my questions seem nub. I just thought I had the necessary
 background for understanding rotation and translation transformations but
 I'm completely confused by how OSG handles these and why it uses different
 coordinate frames in different situations. Anw, perhaps I'm confused by
 DirectX because camera manipulation was much easier with the separation of
 the Modelview matrix in two different matrices whereas in OpenGL you may be
 moving/rotating objects instead of the actual camera viewpoint.

Re: [osg-users] Vicon tracking

[ted morris]

I did something similar a very long time ago with OSG.

I set the ModelView and Projection matrix of the SceneView directly:

setProjectionMatrix( _mtx_proj )
setViewMatrix(vmtx)

for model view you would calculate matrix::makeLookAt and for the projection
matrix
you need to compute your frustum.  Depends on the application how you set
these up.

OSGers-- I'm talking *very old versions* of OSG-- is there now a bundled
'convenience' class that
takes care of this monkey business?

[osg-users] node names not preserved going from flt to ive/osg

[ted morris]

Greetings,

I am having difficulty keeping the node names preserved from open flight
files
(OpenFlight 15.x vintage, I believe) when converted to ive or osg, using
osgconv.exe.

Essentially, the files have a few LOD nodes with different named, group
nodes underneath each of them. Almost all the node names I see in the
ive file (or osg file) are no longer preserved, when I examine them within
my node visitor
in the debugger. When I load the OpenFlight file instead, it is exactly as
expected.

Is this a common problem, and if so, recommendations on a work-around
would be very much appreciated. Loading ive is preferable.

thanks all,

yeah -- it didn't show up back on my e-mail so i thought i goofed on the

 I have never tried the code you're referring to, so other than suggest to
 trace into the code (or place breakpoints where the OSG view matrix is
 updated and in your update callback to make sure the sequence is correct) I
 can't really do much for you.

 But if you want a camera manipulator to track a node, why don't you use the
 osgGA::NodeTrackerManipulator? I've used that in the past, and it works well
 in my experience (though you must track something that has a valid bounding
 sphere - we tried using it to track DOF nodes without children and we had to
 set an initial bound on those or it wouldn't track them correctly, because
 of culling). Also it has the advantage of being part of the core OSG, so you
 can get support for it and if it doesn't work someone will fix it whereas I
 think the NPS tutorials are pretty old and don't necessarily represent
 recent changes to the API and services that OSG provides.


Oh, well that is great advise -- I didn't even know about that built in --
duh!
Man, it has been a while since I worked the library-- I shall definitely
give it a try.




 Hope this helps,


very high probability it will.  :-)

[osg-users] osgGA::NodeTrackerManipulator

Hi,

thanks for suggesting osgGA::NodeTrackerManipulator to follow my
object. How do I get the Camera to stop accumulating the positions
of the object? It keeps getting pushed further and further away as
the object is displaced throughout the path (via a MatrixTransform node).

Or, it is if the Camera keeps getting 'pushed' further away as the
object is being displaced.

Thank you!

 I remember seeing this too. The trick is not to track the MatrixTransform
 itself, but to track its child (if there is no unique child, then reformat
 your graph by creating a single osg::Group below the MatrixTransform that
 contains the MatrixTransform's old children).

 For some reason when you setTrackNode(some MatrixTransform) the transform's
 matrix is applied twice which is what I think you're seeing.

 Hope this helps,

[osg-users] Camera Manipulator

[ted morris]

Greetings,

I'm running into a little snag here.
I utilized the CameraNodeFollower Camera Manipulator as presented in the
NPS tutorial. For all who don't know it basically attaches a node with a
NodeCallback that
obtains the current NodePath of the parent, and multiplies its own offset
from the
parent which is then 'followed'.  e.g., :

struct updateAccumulatedMatrix : public osg::NodeCallback
{
   virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
   {
  matrix = osg::computeWorldToLocal(nv-getNodePath() );
  traverse(node,nv);
   }
   osg::Matrix matrix;
};

OK. What is happening is rather strange. It is attached to a MatrixTransform
object.
When the MatrixTransform is updated with an UpdateCallback,
the underlying object jitters every 1/2 to every 1 second (variable).
It is as if the updating of the object in 'out of synch' with the
CameraNodeFollower
CameraManipulator

When I just attached a built-in CameraManipulator, for example a
sgGA::TrackballManipulator,
I don't have the problem. So, it must something with how I am implementing
this NodeFollowerManipulator.

I tried setDataVariance to DYNAMIC on both the MatrixTransform node (parent)
and
the child node with the UpdateCallback attached as above, and that didn't do
anything.
I also played with:
viewer-setThreadingModel(osgViewer::Viewer::SingleThreaded); no change.

Any ideas how to fix this or what might be happening here?

thanks,
Ted

[osg-users] Camera Manipulator problem

[ted morris]

Greetings all,

I'm using the CameraManipulator from the NPS 11.x tutorial to follow a
MatrixTransform
object. The MatrixTransform position/orientation per usual with an Node
UpdateCallback.

The manipulator simply attaches a node to the MatrixTransform node
with a callback which grabs the parent NodePath (of the MatrixTransform
node),
represented in WOrld coordinates; i.e., per the demo code:.

snip
struct updateAccumulatedMatrix : public osg::NodeCallback
{
   virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
   {
  matrix = osg::computeWorldToLocal(nv-getNodePath() );
  traverse(node,nv);
   }
   osg::Matrix matrix;
};
snip

What happens is that the camera appears to occasionally be updated with the
previous frame's
parent object position/orientation. The affect is that it will 'jitter' say,
every 10 frames or something like that...

I tried to setDataVariance(osg::Object::Dynamic) for both the
MatrixTransform and the node and
still the same problem. But, when I attach a built in CameraManipulator to
the viewer I don't have the
problem.

It is as if the node with the Callback is being called sometimes before,
or sometimes after,  the MatrixTransform parent object's callback. Possible?

What might I be missing? Is there a way to control when the
CameraManipulator is updating
the view matrix?

the app is running under WinXP 32b through wxWIndows/Visual Studio9, if that
matters.

thanks very much for any insights, suggestions, help--

Re: [osg-users] broken osgconv.exe

[ted morris]

hm well thought I did do that. I am able to get it all working on
another PC without installing 2005 *SP1*. just VC90 installed.

thanks,  have a good weekend.

 Ted,

 I downloaded the osg precompiled package you are using 
 (openscenegraph-all-2.8.2-win32-x86-vc90-Release.zip),
 and I checked that indeed, the osgdb_ive.dll depends on a zlib1.dll that was
 compiled with VS 2005 SP1 (which is weird). I presume it is also the case of
 libpng, curl and tiff.

 So, to move on, you have to recompile osg from the sources using the vc90
 dependencies, or install the VC++ 2005 redistribuable packages (there are
 two if my memory serves me right ), I think you didn't install the 2005 *
 SP1* redistribuable package
 (http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647displaylang=en)

 Well, I tried dependencywalker.com and opened up the pluggins.

 I just tried it with the zlib and png dlls contained in VisualStudio 9
 (2008) SP1 prebuild dependencies (
 http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies),
 and I found that the release versions were compiled with the 9.0.30729
 runtime, which is actually 2008 SP1. The debug version, though, was
 compiled with the 9.0.21022 runtime , which is the 2008 runtime. The zlib
 is used in both ive and gz plugins. I don't see  how you get the message
 about the 2005 runtime dependency. Double check in the output window of VS
 that the zlib and png dlls that are actually loaded are the good ones.

ok -- well, since I got it working on another box here at home I presume
there must be another matching dll floating around on that PC.

  These all depend on zlib1.dll, which on my system depend correctly on
  msvcp90.dll. I'm guessing that somehow your system picks up some other
  zlib1. The zlib module is very common so there is a good chance you
  already got it embedded with other software. Try setting the PATH
  explicitly like:
  set PATH=vc90_dependencis\bin;vc90_osg\bin
  before running dependency walker or osgviewer
 
 
  dependencywalker shows that these pluggin dlls are still looking for
  MSVCR80.DLL  *and* MSVCR90.DLL
 
  No, osgdb_tiff, _curl and the other plugin in your list depends on
  msvcr90.dll. However they also depend on many other modules that may,
  in turn, depend on whatever runtime they were compiled against.
  Hitting f9 in dependency walker will show you the full path to all
  listed dlls
 
 
  And the other pluggins can't find MSVCR90.DLL.
 
  I think this is a flaw in dependency walker. I don't have your system,
  but my system reports this too where top dependency msvcp90 depends on
  msvcr90. If this is the case also for you then just ignore.
 
  I'm dropping this for now since I can't find anything wrong with the
  binaries on the website. Drop me screenshots, text logs or whatever
  and I'll investigate further.

Re: [osg-users] broken osgconv.exe

[ted morris]

Hi Mattias,

OK, after checking PATH,
and  setting OSG_NOTIFY_LEVEL=DEBUG,  it finds all the libraries in the
pluggin
and 3rdparty path  but I still get

This application has failed to start because MSVCR80.dll was not found.
Re-installing the application may
fix this problem

for the following pluggins for the RELEASE:

gz
curl
ive
png
tiff

and the following pluggins for the DEBUG:

tiffd

ps: the vcredist_x86 VisualStudio 2005 (v8) runtimes were already installed.
I tried uninstalling them,
re-installing them still no luck.

ps2: I have VisualStudio 2008 (v9) IDE C++ installed.

thanks,
Ted

 Hi Ted,

 I finally got some time to check this out, but can't find any module
 that depends on the vc80 runtime. Everything runs fine and loads pngs
 and fonts without complaints on my xp.
 The machine I have tested on (unfortunatly) have the vc80 runtime on
 it but I'll test this on a clean xp later today or tomorrow. Meanwhile
 could you double check that your system picks up the dll's from the
 3rdParty_binaries_vc90 zip *first*, i.e. if you have libpng13.dll
 and/or friends already in your PATH they may mess things up for you.
 Also - could you crank up OSG_NOTIFY_LEVEL and see if anything gets
 reported there?

  Hmmm, that would seem to indicate that the VC9 binaries depend on the
 VC8
  runtime (probably in addition to the VC9 one). That's pretty weird.
 
  Could whoever compiled those binaries (I don't remember) check that?

[osg-users] broken osgconv.exe

[ted morris]

Greetings, I'm having some trouble using osgconv.exe

after installing
 1)  
openscenegraph-all-2.8.2-win32-x86-vc90-Release.zipfile:///V:/osg/OSG_OT_2.8.2/openscenegraph-all-2.8.2-win32-x86-vc90-Release.zip
 2)  3rdParty_Win32Binaries_vc90sp1.zip

and setting the paths all works fine except for some of the pluggins

when I run osgconv --formats I get a fail dialog box popping up four
times indicating:

This application has failed to start because MSVCR80.dll was not found.
Re-installing the application may
fix this problem

for the following pluggins:

Plugin
C:\OpenSceneGraph\RELEASE\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2/osgdb_curl.dll
not found.
Plugin
C:\OpenSceneGraph\RELEASE\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2/osgdb_gz.dll
not found.
Plugin
C:\OpenSceneGraph\RELEASE\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2/osgdb_ive.dll
not found.
Plugin
C:\OpenSceneGraph\RELEASE\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2/osgdb_tiff.dll
not found.

I also get a similar dialog but for the libpng13.dll  with the osgdb_png
pluggin
Plugin
C:\OpenSceneGraph\RELEASE\OpenSceneGraph-2.8.2\bin\osgPlugins-2.8.2/osgdb_png.dll
not found.

I tried putting msvcr80.dll   in the osg pluggins folder,
in the binary pathed directory for 3rd party libraries:

C:\OpenSceneGraph\3rdParty\bin

or --

C:\OpenSceneGraph\3rdParty\lib
...

etc.,etc.,etc.

with no success.
I would like to be able to use these formats -- particularily ive and gz.

help or suggestions would be greatly appreciated.

thanks all,

T
