Re: [osg-users] [vpb] Quesions about LOD in VPB
Hi David, I assume you do not wand to max out at runtime but at harddsik, right? In this case, it is easy: I've extended osgFileCache some month ago. It supports now also files from local sources. With its ability to limit the caching to certain extend and certain level, you can run it multiple times to build up a limit dataset out of a full dataset. I use it to extract notebook-compatible datasets with hi-res insets from my full TB size terrain dataset.

[osg-users] Osg + Maya status?
Hi all, I'm trying to find a working pipeline between osg 3.01 Maya 2013. I started with intermediate formats (3ds, flt, obj) but no joy, material settings are all messed up. Now I am looking at the native osgMaya: http://maya2osg.sourceforge.net/ but it only supports older version of Maya, i.e 2009/10/11. Has there been any efforts on this plugin for Maya 2013?

Re: [osg-users] Error while loading OSG model on Android
Hi Koduri, I forgot to mention in the previous post that I made video as background by making GL_DEPTH_BUFFER_BIT. That is I used _viewer-getCamera()-setClearMask(GL_DEPTH_BUFFER_BIT ). I have a look at the code of osgAnroidExample. But I am not able to find any specific info about camera settings in any of the C++ files. I think you missunderstood me, I was referring to the project osgAndroid ( https://gitorious.org/osgandroid ). It has a osgCamera example, take a look. Anyway the settings for GlSurface it's done in Java, not in C++. About the matrices you have to study how the OSG manage their matrices respect how vuforia (QCAR) does it. I know quite well this integration it's possible. We have done it, but we are not able to release it as OpenSource :( ... at least at this moment.

Hi David, I can't recall all the options off the top of my head so with the help of osgdem --help and grep I get: $ osgdem --help | grep LOD --LOD Create a LOD'd database. --PagedLODCreate a PagedLOD'd database. --subtile LOD X Y -l numOfLevels Specify the number of PagedLOD levels to generate.

First of all, I'm going to reverence a tool that I know “Terra Vista” for an example. If you don't know about this tool, I understand and try to explain in more detail. One of the tricks you can do in Terra Vista is that you can limit the amount of LOD's you can use in a given area over others. This allows you to build terrain that has higher level of detail in some areas (where it matters ) and allows other areas to max out at a lower level of detail. This in the end would make the terrain take up less space than of all of the terrain was at a high level of detail. I managed to get a group of satellite data at 1 meter resolution and it works fine, but it's taking up over 50 gigs of Hard disk space. I like to cut it back a bit so I can at lease maybe get it on a double layer DVD, if not , a blue ray disk. I figure that if I can cut back on the resolution in areas that I don’t need to be at 1 meter resolution, I can cut the size in whole of the terrain to something more manageable.

Re: [osg-users] Error while loading OSG model on Android
Hi Jordi Torres,
Thanks a lot for the nice help.
To day I did some experiments.
The AR library is giving pose matrix. Now I decomposed it into tans, rotation
and scale vectors. And checked with each one by matrix multiplication. I found
that the translation vector is irrelevant. I got transpose as like 17.98
14.45 155.76 ect. With these values the model is not appread on the screen. If
I set the trans vect as 0.0 0.0 1 then the model is at the center of the screen.
I don't know why this behavior. I am posting in QCAR forum for help.
Is there any think I need to to with OSG?
Here is the complete code again
Code:
int x=0;
int y=0;
int width=screenWidth;

osg::Matrix::translate(0.0,0.0,1.0) * osg::Matrix::rotate(rot));
trans-setMatrix(mat);
_viewer-frame();
Renderer::getInstance().end();
break;
}
I am reading the OSG model every time while rendering. That is for every
viewer-frame(). If not reading the model is displayed only once. Do I need to
take any clean up steps after viewer-frame().
Once again I will go through osgAndroid ( https://gitorious.org/osgandroid )
example.
Once again thank you very much for the nice help.

[osg-users] (no subject)
Hello.
My task is to render an animated dae character with shaders.
I have created a simple vertex shader:
attribute vec4 position_attribute;
attribute vec4 color_attribute;
varying vec4 color;
void main(){
color = color_attribute;
gl_Position = gl_ModelViewProjectionMatrix * position_attribute;
}
After that i use stateset-setAttributeAndModes to assign the program to
the model .
I assign the position and color atrtibute to the corresponding location
according to this:
gl_Vertex 0
gl_Normal 2
gl_Color 3
gl_SecondaryColor 4
Everything works fine.
The problem comes when i try to pass manually the vertex array and color
array using:
geom-setVertexAttribArray(attrib_num, data_array);
geom-setVertexAttribBinding(attrib_num, attrib_binding);
I pass the RigGeometry's VertexArray as data array, but the character is
not animated because the default
geometry's values are passed. Watching the osganimationhardware example i
noticed that i have to pass the bone matrices
as well and multiply with vertex position.
Is there any Array which keeps the updated vertex positions according to
the animation?
If there is, i can match this array's values to position attribute, without
having to pass the matrices in the shader.
Thank you for your time and sorry for the long post.

[osg-users] Problem with osgCamera-setColorMask() or bug?
Hi everybody,
I have a very basic problem and I think I'm doing something wrong
or, maybe, there is a bug.
I've been looking for older posts but I haven't found the solution to
my problem.
In the following program I use setColorMask and it doesn't affect
the rendering in anyway, am I missing something? what am I doing wrong?
//
#include stdio.h
#include osgViewer/Viewer
#include osgDB/ReadFile
#include osg/ColorMask
#include osgViewer/ViewerEventHandlers
#include osgGA/TrackballManipulator
int main ( int argc, char * argv[] )
{
osgViewer::Viewer viewer;
const std::string filename = ..\\data\\cessna.osg;
osg::ref_ptrosg::Node model = osgDB::readNodeFile(filename);
if ( !model.valid() ) {
std::cout Could not find: filename std::endl;
}
viewer.addEventHandler(new osgViewer::StatsHandler);
viewer.setCameraManipulator( new osgGA::TrackballManipulator() );
// GraphicContext
osg::ref_ptrosg::GraphicsContext::Traits traits =
new osg::GraphicsContext::Traits;
traits-displayNum = 0;
traits-screenNum = 1;
traits-x = 10;
traits-y = 10;
traits-width = 1024;
traits-height = 768;
traits-windowDecoration = true;
traits-doubleBuffer = true;
traits-sharedContext = 0;
traits-samples = 8;
traits-alpha = 8;
traits-stencil = 8;
osg::ref_ptrosg::GraphicsContext gc
= osg::GraphicsContext::createGraphicsContext(traits.get());
// Camera
osg::Camera * camara = new osg::Camera();
camara-setGraphicsContext(gc.get());
camara-setViewport( new osg::Viewport(0,0, 1024, 768));
// ColorMask
osg::ColorMask *color_green = new osg::ColorMask( false, true, false, true);
camara-setColorMask(color_green ); //= DOES NOTHING!!
viewer.addSlave(camara);
viewer.setSceneData(model.get());
viewer.run();
return 0;
}
//
If I set the setColorMask directly to the cessna model it works perfectly
but I want to do it in the camera because I use the same model in other
cameras (that should not have the colorMask).
Thanks in advance for any help you can give me.

Hi RigGeometry vertex\normal arrays updated according to animation when software rig transform implementation is used. Have a look at RigTransformSoftware::operator() source. If you set vertex position with setVertexAttribArray, it woudnt be updated, else if you set it with setVertexArray it would be overwritten with array calculated by rig transform implementation.

system and see the error with the camera manipulator. My guess there
is scale issue with the window coordinates and probably something is
missing from the example that should be passing on parameters to
osgViewer. I have plenty of others tasks on my plate so I'll defer to
others for tracking down this issue.
Cheers,
Robert.

Re: [osg-users] Rev 13092 broke osgViewerFLTK
Hi Fredric,
I made the changes to Viewer.cpp w.r.t generation of the frame event
to avoid a bug where the frame event would get the last frames X,Y,
button and key modifier settings rather than the current frames
settings, so I moved the frame generation till later.
I'm guess that the removal of the explict settings of the eventState
InputRange is probably the most likely cause for the difference with
the FLTK viewer rather than just the move of the frame disaptch till
later.
The curious thing is that why doesn't the standard OSG viewer and
other viewers exhibit the same bug as the FLTK one. Perhaps there is
some difference in how the different viewers set up/pass on the
original window dimensions. I think the correct fix will probably be
along these lines.
Just reverting the code as you have done will re-introduce a bug so is
not appropriate.
Robert.

Objet: Re: [osg-users] Rev 13092 broke osgViewerFLTK
Hi Robert,
rev 13092 is a change in osgViewer::Viewer only. Your comment was :
Moved the frame() event into the event traversal after then events and their
state have been accumulated.
In the end, this whole block disappeared :
if (_eventQueue.valid())
{
osgGA::GUIEventAdapter* eventState =
getEventQueue()-getCurrentEventState();
if (getCamera()-getViewport())
{
osg::Viewport* viewport = getCamera()-getViewport();
eventState-setInputRange( viewport-x(), viewport-y(),
viewport-x() + viewport-width(), viewport-y() + viewport-height());
}
else
{
eventState-setInputRange(-1.0, -1.0, 1.0, 1.0);
}
_eventQueue-frame( getFrameStamp()-getReferenceTime() );
}
Any hint why this block should have to be removed ? Does it means it has to
be done at the application level ?

I don't revert the code. I moved the setInputRange block where you put

What I don't see is if the block removal was intended or worked by accident on
most viewer and was unnoticed.

Hi Jan,
Thank you, If it gives you any problem then send me the modified example
and I will try to reproduce it.
I have updated my code and the bug is still there.
You can get my modified example here:

The data files are here (just unpack the folder to /sdcard on your device,
it looks for files /sdcard/osg/*.ive):
https://dl.dropbox.com/u/6822332/osg.zip
Thank you, there is indeed a bug there :S. I was able to reproduce it. I
have also replicated it in native and it worked as expected, so something
is happening in the jni conversion part. I'm debugging now and I will keep
you informed.
I've also checked in changes regarding the camera resolution I hope these
changes will also fix the problems on your side.
Yes, that fixed the camera-related crash.
Perfect!
BTW, there is a syntax error in
org.openscenegraph.android/jni/JNIosgViewer.cpp:

The above makes it actually compile with the latest NDK from Google. You
may also want to raise the minimum SDK level to 8 or 9 in the manifests,
because Lint is complaining about functions being used that are not
available in the old SDK.
Fixed and checked in the repository, thank you!
Maybe we should establish a submission protocol. I think git and gitorious
has something to easily merge changes from different clones. Something
called merge request, but I'm pretty new in GIT and I don't have clear the
complete process.

[osg-users] Looking For An osgPPU RTT Example
Hey guys, I'm looking for some osgPPU example code demonstrating setting up an osgPPU pipeline ONLY on an FBO texture. All of the examples in the project currently--at least, as far as I can tell--appear to always use the Viewer's Camera directly, which won't work for my use. Futhermore, all of my own personal attempts to implement this result in some really crazy results; for example, creating a black, null Viewport inside my SceneGraph with no seeming purpose. I haven't seen much traffic from Art Tevs lately, so if there's an alternative to osgPPU, I'd be willing to try that out too.

Re: [osg-users] Osg + Maya status?
Hello Per, There is no such thing as noise for the OSG list, especially not when it's so directly related to a project in the OSG ecosystem. It's totally relevant and will be useful to someone else I'm sure. So I'm putting this back on the list :-) I didn't go from any pre-existing solution file, I just generated my own with maya2osg's cmake build system (similar to OSG's own). IIRC, I built maya2osgwith an OSG off the SVN trunk, probably close to 3.0. It's been a while though (at my previous employer which I left over 9 months ago) so depending on whether your OSG version is more or less recent it may or may not compile. In that case, you can probably collaborate with Javier Taibo and / or PP (Peter Particle I think it stood for) who were active developers of the project back then and probably still monitor this list. You can also subscribe to its own mailing list at https://lists.sourceforge.net/lists/listinfo/maya2osg-users though I think they are on both so they should see these messages too. Another thing I remember, I would compile maya2osg with an SVN trunk version of OSG, but the models exported from maya in .osg format would read fine in an OSG 2.8.3 viewer. So that's what we did, since our own software needed to use a stable / released / numbered version of OSG, not OSG from SVN). Our pipeline looked like this: 1. Create models in maya 2. Export with maya2osg (compiled against OSG 2.9.x or whatever) in .osg format 3. Optimize the .osg model and save it as .ive using a custom tool based on osgconv (built using OSG 2.8.3, so the binary .ive format was compatible with our software) 4. Use the .ive or the unoptimized .osg in our software (built using OSG 2.8.3) So as I see it you have 2 options depending on the version of OSG you were using to build maya2osg: 1. If it was a recent version (3.1 and up, or current SVN trunk) I'm sure the maya2osg folks will want to update the plugin to build against that version, so you can try to make it work and submit the changes to them or talk to them to see if they're willing to do it. 2. If it was an older version, for example the version you need to build your own software with, you could adopt a pipeline like the one I outlined above. As an alternative to option 2, you could also modify maya2osg to compile against that version of OSG (using #ifdefs with the OSG version to make sure you don't break its compilation against newer versions). But I think that might make the code very messy, so the maya2osg folks might not accept to merge those changes back in, which I think is understandable, and then you'd be left with having to maintain your own private fork of the plugin...

Im trying to compile now but I'm probably using the wrong version of OSG, getting lots of API related errors during compile time. Do you remember which version of OSG you used that matches Maya 2011?

If I succeed I'll post the conclusions there) /Per On 6 September 2012 12:45, Jean-Sébastien Guay jean_...@videotron.ca wrote: Hello Per, I've used Maya2osg with Maya 2012 x64.

[osg-users] intercepting win32 message loop
Hi,
I have quick demo program that basically needs to have two windows, one is an
OSG window and the other is a regular win32 window.
I create the win32 window in a new thread with a message loop
while ( GetMessage( msg, NULL, 0, 0 ) { ...}
It works fine until the OSG window has started (using osgViewer) After that, my
regular win32 window can't receive any message. I think the reason is that
there is just one message queue for the entire program.
I am not 100% sure about this though.
Can someone tell me a quick way to fix this problem? For example, is there
anyway to intercept win32 message inside the viewer?
Thank you!
Cheers,
Ruigang
