Hi, Suppose I use FBO to render the resulting color to a texture (because of some reasons, I am unable to use RenderBuffer), how do I access each texel of the resulting texture ? Thanks.

Use the FBO as a render to texture. Access the texture in your shader with

vec4 texel = texture2D(tex, gl_TexCoord[0].xy);



or if you want to read back the FBO use glReadPixels
or to read back from the texture glGetTexImage
