You can use the Q3RotateAboutPointTransform_New function to create a new rotate-about-point transform.

TQ3TransformObject Q3RotateAboutPointTransform_New (
const TQ3RotateAboutPointTransformData *data);

data

A pointer to a TQ3RotateAboutPointTransformData structure.

DESCRIPTION

The Q3RotateAboutPointTransform_New function returns, as its function result, a reference to a new transform object of type kQ3TransformTypeRotateAboutPoint 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, Q3RotateAboutPointTransform_New returns the value NULL.
