The TextureCoordinate node specifies a set of 2D texture coordinates
used by vertex-based geometry nodes (e.g., IndexedFaceSet
and ElevationGrid) to map textures to vertices.
Textures are two dimensional colour functions that, given an (s, t)
coordinate, return a colour value colour(s, t). Texture map
values (ImageTexture, MovieTexture,
and PixelTexture) range from [0.0, 1.0] along
the S-axis and T-axis. However, TextureCoordinate values, specified by the
point field, may be in the range (-,
). Texture coordinates identify
a location (and thus a colour value) in the texture map. The horizontal
coordinate s is specified first, followed by the vertical coordinate
t.
If the texture map is repeated in a given direction (S-axis or T-axis), a texture coordinate C (s or t) is mapped into a texture map that has N pixels in the given direction as follows:
Texture map location = (C - floor(C)) × N
If the texture map is not repeated, the texture coordinates are clamped to the 0.0 to 1.0 range as follows:
Texture map location = N, if C > 1.0, = 0.0, if C < 0.0, = C × N, if 0.0 <= C <= 1.0.
Details on repeating textures are specific to texture map node types described in 6.22, ImageTexture, 6.28, MovieTexture, and 6.33, PixelTexture.

|
Implements Node. |
|
Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos. Implements Node. |
