I''m using glReadPixels and GL_DEPTH_COMPONENT to import the depth map but i have just a white texture ! My code works well when i use glReadPixels and another format like RGB. I have a GeForce 4 Ti and i''ve tried width a depth 16bit depth buffer and 24bit but just a blank TEXTURE !!!! I know that the glClearDepth is a at 1 by default, i''ve tried to change it but without success ! Any idea ???
