VertexTextureCoordinates

VertexTextureCoordinates
is an option for graphics primitives that specifies the texture coordinates to assign to vertices.

MORE INFORMATION

VertexTextureCoordinates can be used with Polygon and GraphicsComplex.

VertexTextureCoordinates specifies that coordinate should be assigned to vertex i.

The texture coordinates for each vertex can have the following forms:

	{u}	1D coordinates
	{u,v}	2D coordinates
	{u,v,w}	3D coordinates

The texture coordinates u, , and w are assumed to range from to .

Coordinates outside the range to are taken be periodic and equivalent to Mod etc.

Textures are taken to be arrays of colors.

Texture coordinates follow the same convention as position numbers.

For a particular dimension the texture coordinate corresponds to the smallest position and texture coordinate corresponds to the largest position.

For a 1D texture, coordinates correspond to:

	{0}	position , first element
	{1}	position , last element

For a 2D texture, coordinates correspond to:

	{0,0}	position , first row and column
	{1,1}	position , last row and column

For a 3D texture, coordinates correspond to:

	{0,0,0}	position , first row, column, and tube
	{1,1,1}	position , last row, column, and tube

The texture coordinates in the interior of the polygon effectively correspond to interpolating between the texture coordinates specified by VertexTextureCoordinates.

The texture color corresponding to a texture coordinate is computed by interpolating between neighboring colors in the texture.
