Draw to offscreen renderbuffer in OpenGL ES (iPhone)

http://stackoverflow.com/questions/1853551/draw-to-offscreen-renderbuffer-in-opengl-es-iphone

iPhone I'm trying to create an offscreen render buffer in OpenGL ES on the iPhone. I've created the buffer like this glGenFramebuffersOES 1 offscreenFramebuffer glBindFramebufferOES GL_FRAMEBUFFER_OES offscreenFramebuffer glGenRenderbuffersOES 1 offscreenRenderbuffer.. every time. Make sure you draw to the texture only once as in your case things are persistent. void setUpTextureBuffer glGenFramebuffersOES 1 texturebuffer glBindFramebufferOES GL_FRAMEBUFFER_OES texturebuffer create the texture glGenTextures 1 canvastexture glBindTexture..
