Hi Andrew,
Here are a few things that you will need to do to use multiTextures.
(1) Specify number of texture coordinates set in the GeometryArray object
(2) Specify texCoordSetMap in the GeometryArray object.
The values in the array specify the texture coordinate set within
this GeometryArray object that maps to the corresponding texture unit.
All elements within the array must be less than the number of texture
coordinates set specified. A negative value specifies that
no texture coordinate set maps to the texture unit corresponding to
the index. The same texture coordinate set may be used for more than
one texture unit.
(3) Specify texture coordinates for each texture coordinate set
Example:
// in this example, 2 texCoord sets is specified, and there are
// 3 texture units anticipated in the appearance object and that's
// why there are three entries in the texCoordSetMap. texCoordSet0
// is mapped to texture unit 0, and texCoordSet1
// is mapped to both texture unit 1 and 2.
int texCoordSetMap[] = {0, 1, 1};
int texCoordSetCount = 2;
float texCoordSet0[] = {....};
float texCoordSet1[] = {....};
geo = new TriangleArray(
12,
TriangleArray.COORDINATES | TriangleArray.TEXTURE_COORDINATE_2,
texCoordSetCount, texCoordSetMap);
...
// specify texture coordinates for texture coordinate set 0
geo.setTextureCoordinates(0, 0, texCoordSet0);
// specify texture coordinates for texture coordinate set 1
geo.setTextureCoordinates(1, 0, texCoordSet1);
...
Hope this helps.
