I use Apple's Texture2D class but you can use an OpenGL texture id if you want and a frame buffer Texture2d texture GLuint textureFrameBuffer Then at some point I create the texture frame buffer and attach the renderbuffer. This you only need..

render to floating point texture under iOS

Unfortunately I'm having trouble binding a floating point texture to a framebuffer object. Here's my attempt GLuint textureHandle glGenTextures 1 textureHandle glBindTexture GL_TEXTURE_2D textureHandle glTexImage2D GL_TEXTURE_2D 0 GL_LUMINANCE.. GL_NEAREST glTexParameteri GL_TEXTURE_2D GL_TEXTURE_MAG_FILTER GL_NEAREST assert GL_NO_ERROR glGetError this passes GLuint fboHandle glGenFramebuffers 1 fboHandle glBindFramebuffer GL_FRAMEBUFFER fboHandle glFramebufferTexture2D GL_FRAMEBUFFER..
