VertexTextureCoordinates

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

DetailsDetails

  • 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.
