VertexTextureCoordinates
VertexTextureCoordinates
is an option for graphics primitives that specifies the texture coordinates to assign to vertices.
Details
- VertexTextureCoordinates can be used with Polygon and GraphicsComplex.
- VertexTextureCoordinates->{t1, t2, ...} 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[u, 1] 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.
