  Very simple time-distortion for animation blending. Updated March 27, 2004
  

• 

  VIPM Terrain

  Terrain rendered with VIPM of 64x64 chunks. Updated May 24, 2000
  (removed temporarily due to bandwidth excesses; need to make a smaller demo)

• 

  Shadow Mapping

  Shadow map casting demo. Also includes a lighter version of Terrain, and Actors using VIPM in real-time combined with smooth-skinning, running at One MTriHz. Posted May 15, 2000
  download shadow1.zip (1.9 MB)

• 

  Progressive Meshes

  Very fast View Independent Progressive Mesh demo. This is a very early demo of VIPM; better ones will follow. Version 2 now includes VIPM's for the Stanford Bunny and Budha models, Updated Mar 30, 2000 download pmtest.zip (2.8 MB)

  Continuous-LOD Terrain

  Continous-LOD dynamically tesselation view-dependent terrain. Adjusts tesselation for the actual running speed, tesselates more in silhouttes and adds polys only where needed. Fly-by and walk-around modes. Updated Feb 4, 2000 download terraindemo.zip (3 MB)

• 

  L-System Trees

  Procedurally generated (L-System) tree. The Tree object extends the Curve and TriMesh objects in GameDriver; this is a cool demo of a user-extension to the gamedriver plugin objects. Play with the L-System parameters, and grow your own trees. Updated Mar 8, 2000 (removed temporarily due to bandwidth excesses; need to make a smaller demo)
