This node defines a set of 2D coordinates to be used to map textures to subsequent vertex-based shapes (those derived from
SoVertexShape). It replaces the current texture coordinates in the rendering state for the shapes
to use.
The current texture coordinate binding (see
SoTextureCoordinateBinding) determines how texture coordinates are mapped to vertices of shapes. An alternative to using explicit texture coordinates is to generate them using
a function; see
SoTextureCoordinateFunction.
Texture coordinates range from 0 to 1 across the texture. The horizontal coordinate, called
S, is specified first, followed by the vertical coordinate,
T.
