Functional Details
This module prepares a specified object for being moved, rotated, and resized. A Transform object containing the specified transformation matrix is inserted at the root of the object. This transform is applied during rendering.
The module is more primitive than Translate, Rotate, and Scale, but it allows direct entry into a 3×3 or 3×4 matrix (for combining several transformations or for a skew transform).
Each [x y z] point in the object is transformed to the new point [x' y' z'] by: < lb x prime %% y prime %% z prime rb > equals < lb x %% y %% z rb left lb < <a %% b %% c> lvabove <d %% e %% f> lvabove <g %% h %% i> > right rb plus lb j %% k %% l rb >
Nine numbers are interpreted as a to i with no translation; twelve numbers are a to l. No translation occurs for the default value of: left lb < <1 %% 0 %% 0> lvabove <0 %% 1 %% 0> lvabove <0 %% 0 %% 1> > right rb plus lb 0 %% 0 %% 0 rb
Components
All input components are propagated to the output.
