Thanks Cedric,  the downloads page links to your website already so no
need to update.

A small question though, which version of the OSG will

  emerge openscenegraph

Pull in?  I presume the latest stable version.

Robert.

Re: [osg-users] Converting from Partiview - suggestions?

Hi Jeff,

As Sukender mentioned the way to add parsing of external files for
generation of the 3D models is by writing a plugin that gets loaded
dynamically by your application.  There exsiting OSG plugins will
probably help you in working out what to write.  Many of the plugins
are just a single file that provides a ReaderWriter implementation to
does the reading directly of via a 3rd party lib that does the
parsing.  The 3dc plugin is pretty simple so might a good place to
start as a template for you own code.The nice thing about plugins is
that they are self contained and can work with any OSG application,
including the standard osgviewer.

If you don't want to go the plugin route you could easily just do your
parsing/scene graph creation code in your a test application, then
when you migrate to using a plugin once you get a bit more
comfortable.

As for Partiview - this is a pretty cool app, it would be great to see
something similar implemented on top of the OSG.  I have a colleague
who does educational shows using stereo projection with Partiview as
part of the show and he's frustrated by the lack of flexibility when
it comes to handling unusual display configuration - if it was OSG
based then the OSG's more powerful viewer configuration capabilities
would make it possible to use different types of projector/machine set
ups.  Are the original developers still active at all?

Robert.

[osg-users] osgdem generated .ive (Type osgTerrain) crashes osgviewer

2009-02-16 Thread Christian

hi,

if i build my terrain out of GEOTIFF rasterfiles in a way like this:

---
osgdem --TERRAIN -l 3 -t ..\source\boston-10m-utm19n-meters.tif -d 
..\source\boston-dem-downtown-5m-utm19n-meters.tif -o out.ive -v 3
---

the osgviewer utility crashes when i load the generated .ive file.
if i omit the --TERRAIN option , the resulting .ive works in the viewer.

if the other GeometryType (polygonal) is preferred anyway, i have no
problem using it. i just wanna get sure that there isnt something wrong with my 
osg installation because the osgviewer crashes.

btw. is the benefit of using osgTerrain?

i'm using:
*osg-2.8.0 (with GDAL)
*GDAL 1.6.0dev from FWTools 2.0.4
*dependency-pack from the websites (osg-dependencies-vs80sp1)
*VirtualPlanetBuilder-0.9.9

Hi Christian,

I would check to make sure you're graphics card / driver supports VBO's
properly.  I had a similar problem with osgTerrain based VPB databases on an
Intel graphics chip and it turned out that VBO's were the issue.

See what happens if you disable VBO by setting the OSG_GL_EXTENSION_DISABLE
environment variable to GL_ARB_vertex_buffer_object.

Good luck!

[osg-users] How to create detection, crossing from Vega(Multigen) to OSG.

2009-02-16 Thread petr

Hi All,
I'm a new osg user and these days I'm trying to use it. Now i have tried some 
tutorials and read some docs, and i have one questions.

because we have used for visualization Vega (by Multigen, now Presagis), ve can 
add to scene some Isectors whitch checked collisions with another objects, or 
hold the cars on the road. Can i do this  in OSG (i didn't found Isectors theme 
on this website), and how to do it? 

Here is the part how to create Isector (create, position, masks, callback) in 
Vega:

#define VGIS_TERR1 0x0001   //terrain face, for callback
#define VGIS_SOBJ1 0x0100   //static face, for callback

vgIsector *isector;
vgPosition *pos; //(x,y,z,h,p,r)

pos=vgNewPos();
vgPosVec(pos, 0.0f,0.0f,0.0f,0.0f,0.0f,0.0f);

//isect example
isector=vgNewIsect();   //new Isect
vgPos(isector, pos);//pos
vgIsectTarget(isector, vgGetScene(0));  //target detect (scene)
vgIsectClass(isector, VGIS_TERR8);  //mask
vgAddPlyrIsect(mv_player, isector); //isetc to player
vgAddFunc(isector, VGIS_HIT, callback, param);  //callback
vgUpdate(isector);  //update
vgDelPos(pos);  //del tmp pos


And some screenshot from runtime loop, the green line is detecting, red no. 
Z-isectors hold the cars on the road. 3rd image - left isector is greeen 
because ho has crashed with white cube (static object).

Re: [osg-users] Resolving CDash errors/warning


Hi Philip,

I really haven't been monitoring the status of the OSG for quite a while 
now so I'm not extremely familiar with how you guys are kicking off your 
nightly builds.


Our nightly builds are just additional projects in the VS solution / 
makefile. So we do either


  make Nightly

or

  devenv path to OpenSceneGraph.sln /build Release /project Nightly

Typically at work we use cron or Windows Scheduled Tasks to run the 
following command to build our source tree.

ctest -S foo.cmake

foo.cmake would contain something similar to the following:
http://www.cdash.org/CDash/viewNotes.php?buildid=271884
http://www.cdash.org/CDash/viewNotes.php?buildid=271534

This allows us to tweak the initial cache to enable / disable various 
dependencies, etc.


http://www.cmake.org/Wiki/CMake_Scripting_Of_CTest


Interesting, I'll have to take a look at this.

Re: [osg-users] How to create detection, crossing from Vega(Multigen) to OSG.

2009-02-16 Thread Brian R Hill

Petr,

OSG is very different from vega (I switched to osg from vega years ago).
Your general experience using vega will be helpful, but the details of how
to implement specific functionality will not be very helpful. There are a
number of tutorials available, and the examples are invaluable.

For your intersection question, you'll need to use osg's
osgUtil::IntersectionVisitor (look at the osgintersection example).

Re: [osg-users] How to create detection, crossing from Vega(Multigen) to OSG.

2009-02-16 Thread Gordon Tomlinson

OSG provides intersections testing 

See osgUtil::IntersectionVisitor, this is quite different though from what
Vega/Vega Prime provides

Note you will have to do more work/coding with OSG when using Isectors than
you would with Vega/VegaPrime
You will have to us the osgUtil::IntersectionVisitor  create equivalents to
like Vegas  HAT, LOS, Z, Tripod, 
ZPR, BUMP isectors.  etc. and then manage them, what updating them means
etc..

Also note the OSG only has one Node Mask to be used for Draw, Cull, APP,
Isectors etc, no separate ones as in Vega

OSG is very powerful and provides a lot, but in many cases not as much as
Vega/Vega Prime in some case  provides
much that Vega did not, but more at the lower level , generally you need to
know more of the nuts and bolts do with
OSG than you did with Vega

The best way I can describe the differences is if Performer/Vega, Vega added
an abstraction to make it  easier to use Performer
And extend it a little/lot in places, you lose that abstraction when moving
to OSG , and if you know/knew performer then it's easier
to think of OSG - Performer

2009-02-16 Thread Jeff

Thanks... I'll take a look.
Because I don't really have a solid format, I can probably write my scripts to 
output in whatever format would be the easiest to work with in OpenSceneGraph.  
Perhaps the .osg.  I'm just trying to understand the format.  Perhaps the 
VRML importer would be better.

Another solution could be to use scripting directly with OSG. Look into 
osgLua, osgPython, osgSWIG, ... which will allow you to create scripts 
that generate/manipulate OSG objects without writing and compiling C++ code.

[osg-users] default lighting

2009-02-16 Thread Ben Axelrod

When I don't have any lights in my scene, and my viewer's lighting mode is set 
to no_light:

osgViewer::Viewer() - 
getCamera()-getView()-setLightingMode(osg::View::NO_LIGHT)

there is still some default lighting in the scene.  Where does this light come 
from, and how can I change it to be brighter or darker?

[osg-users] problem with Windows debug binaries?

I downloaded the debug and release binaries from
http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8/binaries/Windows/VisualStudio8/.

When I try to run any of the exe's, I get a message that says:
  The application failed to initialize properly (0xc0022). Click on
OK to terminate the application.

I've seen this before and it has either been a permissions problem or a
CRT version mismatch problem. I'm running Visual Studio 2005 which
(AFAIK) is generally called version 8, so it shouldn't be a version
problem. If I use runas to run osgversion.exe as administrator, I get
the same error, so it shouldn't be a privileges problem. So now I really
don't know what it could be.

Up until today, I've always been running exe's that I compiled myself.
This is the first time I've run OSG from a prebuilt binary.

Is anybody else having this problem? Any troubleshooting suggestions?

Re: [osg-users] problem with Windows debug binaries?

Yes, I have SP1.

I just noticed that none of the dll's have the execute bit set. My
cacls knowledge isn't good enough to know exactly what it is that
should be set. It's easy to just grant everyone full control (and it
does fix the problem), but I suspect that isn't the correct solution.

I just downloaded all the binaries and unzipped them all to the same

other OSG binaries on my PATH).


You don't mention if you have SP1 installed on your installation of VC8. 
That could well be the problem. You need to have either the VC 2005 SP1 
redist or VC 2005 SP1 itself for binaries built with VC 2005 SP1 to run.

Wow- when I untar with 7-zip I get different results than when I untar
with cygwin (the file permissions are different). Cygwin gives me exe
files with the execute bit set, but none of the dlls have that bit set.
7-zip just gives everyone full control. After searching through the
7-zip forums, it seems that it doesn't support maintaining ACL's.

Just out of curiousity, what tool was used to create the tarballs?

Re: [osg-users] problem with Windows debug binaries?

I just did a little experiment with 7-Zip and ACL's. I created a file
and gave it weird privileges. I tar'd it with cygwin. When I untar
with cygwin, the ACL for the file is restored correctly. When I untar
with 7-Zip, the ACL has been replaced with one that grants full access
to everyone.

Likewise, if I tar with 7-Zip, it trashes the ACL for the file (in the
archive). It doesn't matter what I use to extract with. The privileges
information has been lost.

7-Zip might be a wonderful compression tool, but I don't think much of
it's archiving capabilities. I would not recommend it.

Re: [osg-users] [vpb] osgdem terrain creation - OpenGL 'invalid enumerant'

Hi Christain,

The warning suggests an issue with your OpenGL driver.  Perhaps
updating the driver will fix the issue.

The other route would be to disable the use of OpenGL compression of
tiles by selecting a non compression image target such as by using the
--RGB or --RGBA command line option.

 Greetings,

 I am trying to make a visualization of a building in 3DS, and it looks
 like the floor always looks dark, even if material/texture is light. I
 tried even to make the floor plain white, and it appeared quite dark
 gray. If I rotate, it always appears that darkened are surfaces that
 happen to be down related to the camera.

 Does anybody knows what to do about this darkening effect? Is it
 something that I can control?
