Hi CHris,
A texCoordSet is a set of textuer coordinates for the geometry. When you do multi
texturing you can specify several sets fo
texture coords, and then you can specify which set of texture coords to use with each
texture unit. To specify which set of tex
coords to use with each tex unit you must pass an array into your geometries
constructor (the texUnitMap). This array has one
entry for each texture unit you will apply to the geom. Each entry specifies which set
of textrue coords to use for each tex
unit.
eg.
I have 2 textures I wish to apply to a geom, each using a different set of textrue
coords. I want the first tex unit to use the
first set of texCoords and the secound to use the secound.
When I create the geometry I use a texUnitMap = new int[] {0,1} in the constructor.
I set the texture coords using: geomArray.setTextureCoordinates(0, 0, texCoords);
for the first set of texCoords and: geomArray.setTextureCoordinates(1, 0, texCoords2);
foor the secound.
Now when I apply a texure with two texture units then the first will be applied to the
geom. using texCoords and the secound
using texCoords2.
I hope this makes sense.
Cheers,
Brad
