Transform Objects Routines

Creating and Manipulating Scale Transforms

QuickDraw 3D 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.

IMPORTANT

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.
