The components of the <triple> multiply the coordinate values of points for each of the x, y and z directions with respect to the origin. A scale of (1,1,1) has no ef-fect on the objects, while a scale of (1, 1, 1.5) creates a 50 percent increase in the z dimension. Note that a scale of (0, 0, 0) is an error; it is ignored by the renderer, and a warning message is given. The end of a scale statement is marked by a semi-colon.
