Issue of Stencil buffer rendering with PVRVFrame



Hi All,

I need to use GL_DEPTH24_STENCIL8_OES as the “internal format” for glRenderbufferStorage OpenGL ES 2.0 API. Now this internal format is part of OpenGL ES 2.0 extension. I guess it is not yet supported by PowerVR OpenGL ES 2.0 libs (PVRVFrame GUI shows this API in red, says “unsupported internal format”).

I have NVidia Quadro FX 1800 running on Windows.

I would like to know:-

A) Whether GL_DEPTH24_STENCIL8_OES is supported currently or not.

B) If supported, then why my stencil using objects do not render properly.

Note: If I compile my application with AMD’s OpenGL ES 2.0 Libs & DLLs, I get my objects rendered properly.

Thanks in advance.
