Issue of Stencil buffer rendering with PVRVFrame

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.
