"It is the duty of every cultured man or woman to read sympathetically the scriptures of the world. If we are to respect others' religions as we would have them respect our own, a friendly study of the world's religions is a sacred duty."
- Mohandas K. Gandhi

Required:

Recommended:
GL_ARB_texture_compression

This demo renders a simple scene into a texture. Then it draws a quad over the screen with this texture and applies a Laplace filter through a fragment shader to the texture. This will extract the edges in the picture.
Will run on Radeon 8500 and up.
