This application demonstrates Relief Mapping using two linear searches, a dynamic sky shader and HDR Rendering. Relief Mapping gives flat surfaces a three-dimensional appearance without adding new geometry. Depth Correction further enhances the effect by producing correct silhouettes along surface intersections. A sky shader allows you to control the cloud cover and the cloud density. Finally a separable HDR bloom filter gives the scene a smooth finish.
