You can use the Q3RotateAboutAxisTransform_New function to create a new rotate-about-axis transform.

TQ3TransformObject Q3RotateAboutAxisTransform_New (
const TQ3RotateAboutAxisTransformData *data);

data

A pointer to a TQ3RotateAboutAxisTransformData structure.

DESCRIPTION

The Q3RotateAboutAxisTransform_New function returns, as its function result, a reference to a new transform object of type kQ3TransformTypeRotateAboutAxis using the data passed in the data parameter. The data you pass is copied into internal QuickDraw 3D data structures. If QuickDraw 3D cannot allocate memory for those structures, Q3RotateAboutAxisTransform_New returns the value NULL.
