I modified the osgpackeddepthstencil sample the following way and it just
doesn't work.
Code:
if(usePDS)
{
osg::Texture2D *textureDS = new osg::Texture2D;
textureDS->setTextureSize(1024, 1024);
textureDS->setInternalFormat(GL_DEPTH_STENCIL_EXT);
rttCamera->attach(osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, textureDS);
}
I'm using the latest nVidia drivers on Windows 7 x64 and OSG 2.8.
When looking things up with an OpenGL tracer (I used glslDevil here) the error
is generated upon the following call made by OSG:
Code:
glTexImage2D(GL_TEXTURE_2D, 0, 34041, 1024, 1024, 0, GL_DEPTH_STENCIL_NV,
GL_UNSIGNED_BYTE, 00000000)
OpenGL error GL_INVALID_ENUM detected
34041 = 0x84F9 = GL_DEPTH_STENCIL_NV according to GLew.h
Is this a bug, or am I doing something wrong?
