Relief Mapping demo using FBO and OpenGL ARB vertex and fragment programs

This application demonstrates relief mapping using two linear searches. Relief Mapping gives flat surfaces a 3D appearance without adding new geometry. Depth correction further enhances the effect by producing correct silhouettes along surface intersections.  The demo also features a sky shader which allows you to control the cloud cover and the cloud density. Finally a separable HDR bloom filter gives the scene a smooth finish. OpenGL ARB vertex and fragment programs and the EXT_framebuffer_object extension were used to achieve the effects.
