3.48 TextureCoordinate

TextureCoordinate {
  MFVec2f   point   []   # (-inf,inf)
}

The TextureCoordinate node specifies a set of 2D texture coordinates used by vertex-based Geometry nodes (e.g., IndexedFaceSet) to map textures to vertices. Textures are two-dimensional color functions that, given a coordinate pair (s,t), return a color value color(s,t). Texture map values (ImageTexture) range from 0.0 to 1.0 along the s and t axes. Texture coordinates identify a location (and thus a color value) in the texture map. The horizontal coordinate s is specified first, followed by the vertical coordinate t.
