maps images to geometry nodes.
apply multiple textures to a single set of geometry,
enabling a variety of visual effects such as light mapping and environment mapping.
node can contain multiple ImageTexture, MovieTexture and PixelTexture nodes.
node can contain TextureCoordinate or TextureCoordinateGenerator nodes.
node contains TextureTransform nodes that correspond to each texture image.
techniques apply volumetric textures that describe a volume in space, rather than a flat surface.
