Parameters:

void Teddy::Models::Geometry::makeCubicTextureCoordinates ( Vector center,

Vector size

)

Calculate cubic texture coordinates for Geometry.
Calculate cubic texture coordinates for Geometry
Parameters:

center Texture center

size Texture size

Texture coordinate calculation for Geometry is done Element by Element.
For each Element, we calculate a new texture coordinate for each Vertex of the Element.
If the Vertex in the Element does not yet have a texture coordinate set, we will set the new texture coordinate to the existing Vertex.
If the Vertex in the Element does have the same texture coordinate as we just calculated, we do nothing to it.
If the Vertex in the Element has a different texture coordinate, then we replace the old Vertex pointer in Face's Vertex list with a new Vertex that inherits the old Vertex but has the new texture coordinate. The old Vertex is not changed, and other Face's Vertex lists still point to it.
This routine is not recursive; sub-Geometryes are not processed.

This routine is not recursive; sub-Geometryes are not processed.
Here are some simplified code fragments showing how LightWave computes UV coordinates from X, Y, and Z. If the resulting UV coordinates are not in the range from 0 to 1, the appropriate integer should be added to them to bring them into that range (the fract function should have accomplished this by subtracting the floor of each number from itself). Then they can be multiplied by the width and height (in pixels) of an image map to determine which pixel to look up. The texture size, center, and tiling parameters are taken right off the texture control panel.
