Hi Rafael,
I'm not sure but I think JavaOSG does not continue active.. anyway I think
the problem could be related to:
Texture2D myTexture = new Texture2D();
myTexture= null;
Image img = new Image();
img =null;
If you do a "new" and after you set the variable to "null". Probably
Hi Steven,
I'm not so sure, but maybe you should try to set the render target
implementation to FRAME_BUFFER_OBJECT, as done in the prerender example?
What graphics card do you use?
Does it work for you with GL_RGBA16F_ARB?

I'm getting all 0s for my pixel buffer when I use GL_RGBA32F_ARB
Hi!
I'm attempting to know the Algorithm of Triangle Mesh Simplification Based

Thanks in advance!

The forum software doesn't allow files with no extention.
I have tried several different browsers but it seems to be a server problem -

This is a problem attaching OSG's famous extentionless headers.

Hi Robert,
I was wondering if there was a way to know when all draw threads for a
given frame have finished rendering? Since the update traversal for
frame i+1 can start before the draw traversal of frame i is completed
(for STATIC objects), we'd like to get some kind of signal to know when

Thanks for your reply!
Actually I update my texture with frames from a sequence.
That's why I must turn my OpenCV image to an OSG.

Hi Vincent,
Thanks for your advice, but node doesn't have the method getWorldMatrix(), it
has only getWorldMatrices().
I tried this:
osg::Vec3 position = node->getBound()->center() * node->getWorldMatrices()[0];
but it returned same value like this:
osg::Vec3 position = node->getBound()->center()
That's nice :)
what are we to do with those totally out of context dimensions ?

I'm getting all 0s for my pixel buffer when I use GL_RGBA32F_ARB as the pixel
format.
It works fine with GL_RGBA.
This is how I set it up:
i = new osg::Image();
i->setPixelFormat(GL_RGBA32F_ARB);
i->setDataType(GL_FLOAT);

Hi Albert,
I just did a project with the Blue Marble Next Generation data (BMNG), and I
just loaded the jpg tiles and used them to texture polygons. The BMNG data
set goes from -180,-90 to 180,90, and there are 5 rows by 10 columns in the
base set, and each set beyond that doubles the rows and colu
Max,
For starters, you probably want GL_RGB8 (0x8051) and not GL_TEXTURE_2D
(0x0DE1) in your setImage call.
But in general it looks a bit odd to me, and I'm not sure what your
intention was. First you get the pointer to the textures image, and then you
set it to something else. I imagine you just

I was curious if anyone out there knows a site where I can download a
