The current method is GL_EXT_framebuffer_object and there is an example at developer.nvidia.com

If you are targeting mobility ATI devices like mobility FireGL v3100 or some other cards that don't have support for GL_EXT_framebuffer_object (at least not in the Dell supported drivers) you may want to look into pBuffers.

Here is a sample:
