README for NvTriStrip, library version
|
||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
||
|
To use:
|
||
|
-#include "NvTriStrip.h"
|
||
|
-put nvtristrip.lib in your library path (the pragma in nvtristrip.h will automatically look for the library).
|
||
|
|
||
|
Check out NvTriStrip.h for the interface.
|
||
|
|
||
|
See the StripTest source code (in function LoadXFileStripped) for an example of using the library.
|
||
|
|
||
|
Features:
|
||
|
-generates strips from arbitrary geometry.
|
||
|
-flexibly optimizes for post TnL vertex caches (16 on GeForce1/2, 24 on GeForce3).
|
||
|
-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.
|
||
|
|
||
|
On cache sizes:
|
||
|
Note that it's better to UNDERESTIMATE the cache size instead of OVERESTIMATING.
|
||
|
So, if you're targetting GeForce1, 2, and 3, be conservative and use the GeForce1_2 cache
|
||
|
size, NOT the GeForce3 cache size.
|
||
|
This will make sure you don't "blow" the cache of the GeForce1 and 2.
|
||
|
Also note that the cache size you specify is the "actual" cache size, not the "effective"
|
||
|
cache size you may of heard about. This is 16 for GeForce1 and 2, and 24 for GeForce3.
|
||

|
Credit goes to Curtis Beeson and Joe Demers for the basis for this stripifier and to Jason Regier and
|
||
|
Jon Stone at Blizzard for providing a much cleaner version of CreateStrips().
