Patch Based Terrain

What it is

This is a patch based terrain system which adjusts the level of detail based on the proximity of the camera and the base level of detail for any given patch. The base level of detail is used by calculating the root means squared. The patch based system also features frustum culling and per pixel illumination with a normal map generated from the Height map. The heightmap is given in a binary terrain file format (link), and represents the island of Hawaii.

Key Feature:

  • Distance and intrinsic LOD
  • Frustum culling
  • Per pixel lighting
  • BT file format loader
  • Patch based system
  • Terrain stitching
