I want to render a shadow map (i.e. render the depth to a texture). First question: Can I do it all by myself, using a fragment shader and glCopyTexImage2D? In that case, how do I setup the texture (internal format and so on). And how do I set the "color" from the fragment shader. I only want to set the color to the depth, by isnt the the fragment shader supposed to return 4 components? Secondly, can I use a shadow map as a texture? Right now Im trying to create a shadow map using an extension, and create the texture using GL_DEPTH_COMPONENT. But is there any way I can visualize the shadow map by just putting this texture on a quad or something?
