MotionBlur : Transformation Motion Blur

There are three types of motion blur supported by Houdini, TransformationBlur, VelocityBlur and DeformationBlur.

Transformation blur can be used when the geometry for the object isn't changing frame to frame. Transformation blur only takes the transformation matrix (WhatIsAMatrix?) of an object (and a camera) into account.

This is the cheapest form of MotionBlur for Houdini to compute since only one set of geometry needs to be output to the renderer. It also cuts down on the parsing time of the renderer (i.e. the renderer has to do less work to parse the script).

Note: VelocityBlur and DeformationBlur both encompass TransformationBlur
