NVTriStrip is a library for vertex cache aware stripification of geometry.

Features:

  • generates strips from arbitrary geometry.

  • flexibly optimizes for post TnL vertex caches.

  • can stitch together strips using degenerate triangles, or not.

  • can output lists instead of strips.

  • can optionally throw excessively small strips into a list instead.

  • can remap indices to improve spatial locality in your vertex buffers.

  • API and OS independent.

Update Feb. 17, 2004:
Fixed memory leaks.
