7 Creating and Manipulating Scale Transforms
QuickDraw3D provides routines that you can use to create and manipulate scale transforms. A scale transform scales an object along the x, y, and z axes by specified values. You are responsible for ensuring that an object is at the correct location and in the proper orientation for the scaling to have the desired effect.
A scale factor can be negative. You should, however, exercise caution when using negative scale factors. In addition, when two or three of the scale factors are 0, nothing is drawn.<8bat>s
