Render to texture or pBuffer on Intel 2700G

Hi all,

I am looking for a solution to render with an Intel 2700G device (e.g. part of DELL Axim x50v) using openGLes to an off-screen region.
My idea is to either render to a texture or to a pBuffer.

Anybody succeeded in doing this somehow with that device?
Thank you in advance!

Unfortunately, neither pbuffers nor pixmaps are supported on the Intel 2700G. … .php?t=731

Thank for the fast reply!

I made some research on the Internet and I found the following Page: … owerVRSDKs

I downloaded e.g. the ARM VP linux Package. In the OpenGL-ES 1.0 header files

eglCreatePbufferSurface() is mentioned.

a) I thought pBuffer-support should only part of OpenGL-ES 1.1 not 1.0
b) Somebody tried that functionality already?

eglCreatePbufferSurface is, as the name implies, part of EGL, not OpenGL ES. It has been there right from the start, i.e. in EGL 1.0. However, the presence of this function does not imply that pbuffers are supported, since an implementation is not required to expose any pbuffer-compatible EGL configurations. In other words, eglCreatePbufferSurface may always fail.

While Intel only supports OpenGL ES 1.0 Common Lite profile and no pbuffers on 2700G, other PowerVR MBX enabled platforms (including ARM VP and OMAP2 family) may support OpenGL ES 1.1 Common profile and pbuffers. Support for features and extensions might even vary for different devices based on the same SoC, as a device manufacturer may choose not to expose some functionality.
