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.
