Hi!
I'm implementing a shadow map algorithm (with ARB_DEPTH_TEXTURE and ARB_SHADOW) and have finally managed to get a shadowed scene http://www.opengl.org/discussion_boards/ubb/smile.gif However, I'm having trouble with the light's field of view settings. I'm inexperienced with OpenGL and shadow-maps, so this may have an easy solution.
When the field of view is about 50 - my scene gets partially black (black where the light-view can't see). But when I increase it, the shadows get really blocky (I use a 512x512 map).
Is there any way to show the areas the light view can't see in the final scene, or is there another solution to this problem?
Thanks,
- Monica
