Description

These templates define a Graphics Display Kit transformation. GDxform_templ and GDxform define an instanceable version without default values. DefaultXform defines an instanceable version with default values.

You can connect a DefaultXform to an object, light, or camera.

Subobjects

mat

The transformation matrix. This matrix represents only rotation and scale.

xlate

A position vector. This vector defines the current position. It is added to the transformation matrix. It is kept separate so a fixed center position can be defined.

center

A center vector. The vector defines the center to be used for rotation and scaling.

ocenter, dcenter

These are used internally by the methods associated with the transformation and you should not use them.
