Tks 4 your answer.. i'll try http://www.opengl.org/discussion_boards/ubb/smile.gif

But.. is that the only way?

PS.: I want this because I'll do an operation "or" between 3 different RGB Channels buffers and then show the result at screen.

I can't say it is the "only way" based on the limited info given. There could be many possible ways, depending on the minimum hardware requirements and the restrictions you have on what is rendered to the buffer.
