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:
Code:
// Color buffer
Texture2D *texture = new Texture2D();
texture->setTextureSize(320, 200);
texture->setInternalFormat(GL_RGBA);
camera->attach(osg::Camera::COLOR_BUFFER, texture);
// Stencil buffer
Texture2D *textureStencil = new Texture2D();
textureStencil->setTextureSize(320, 200);
textureStencil->setInternalFormat(GL_STENCIL_INDEX8_EXT); // I've tried
GL_STENCIL_INDEX, too
camera->attach(BufferComponent.STENCIL_BUFFER, textureStencil);
viewer->frame();
In the osgpackeddepthstencil sample, I can see the following comments:
Code:
if(usePDS)
{
rttCamera->attach(osg::Camera::PACKED_DEPTH_STENCIL_BUFFER,
GL_DEPTH_STENCIL_EXT);
}
else
{
// this doesn't work on NVIDIA/Vista 64bit
// FBO status = 0x8cd6 (FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT)
rttCamera->attach(osg::Camera::DEPTH_BUFFER, GL_DEPTH_COMPONENT);
rttCamera->attach(osg::Camera::STENCIL_BUFFER, GL_STENCIL_INDEX8_EXT);
}
As I am using Windows 7 x64 with an nVidia card, I tried setting things up with
a packed depth+stencil buffer. But I've got the same error.
Any idea?
Cheers,
Fred
