DiRT 2 - Water - DirectX 11
An example of hardware tessellated dynamic water surfaces using DirectX 11 in DiRT 2. Many areas of the track are covered in water. The CPU generates the height field texture when cars drive through it. The tessellator using ATI Radeon hardware generates hundreds of triangles based on the camera position. The result: A beautiful, physically accurate, dynamic water surface. In the DirectX 9 version of the game, the surface is an illusion represented by just two triangles.
