Hi JP,
As soon as I attach an image, OSG crashes on me. The problem arises in
FrameBufferObject::Pimpl::Pimpl.
Code:
// This code crashes
osg::Texture2D *texture = new osg::Texture2D();
texture->setTextureSize(1024, 1024);
texture->setInternalFormat(GL_DEPTH24_ST
Hi Fred,
we've also encountered cases (float formats) where we need to call:
void setInternalTextureFormat(GLint internalFormat);
after allocateImage in the case of using Images to read back data. If
you look at allocateImage code, you'll see why.
Can you check if this works for you without
This looks like an OSG bug to me. The code is in osg\Texture2D.cpp, in
Texture2D::apply.
With PACKED_DEPTH_STENCIL_BUFFER, internalFormat should be
GL_DEPTH24_STENCIL8_EXT, format should be GL_DEPTH_STENCIL_EXT and type
GL_UNSIGNED_INT_24_8_EXT.
The current OSG 2.8 code makes this GL_DEPTH_STE
I've also tried with an image:
Code:
Image *pdsImage = new Image();
pdsImage->allocateImage(256, 256, 1, GL_DEPTH24_STENCIL8_EXT,
GL_UNSIGNED_INT_24_8_EXT, 1);
camera->attach(PACKED_DEPTH_STENCIL_BUFFER, pdsImage);
This code results in the following error and then the application crashes.

Maybe :
textureDepthStencil->setInternalFormat( GL_DEPTH_STENCIL_EXT );
...
camera->attach(osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, textureDepthStencil);
Could work. As the depth and stencil buffer are packed, so should the texture.

Then how can I read back stencil buffer data?
Thanks,

The following works fine:
camera->attach(osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, GL_DEPTH_STENCIL_EXT);
Why doesn't it work if I create a texture? I need to create a texture and an
image, as I want to retrieve stencil buffer data after frame() has been called.
Cheers,

Hi,
I've got the following 2 errors when frame() is called, when I've got a stencil
buffer attached to my camera:
RenderStage::runCameraSetUp(), FBO setup failed, FBO status= 0x8cd6
Warning: detected OpenGL error 'invalid enumerant' at end of SceneView::draw()
My RTT code looks like this:
