Detailed Description

Root transform for a group of instances.

Transforms position to camera position so that instance spatial data can be camera-relative (i.e. fit in a float32)

Constructor & Destructor Documentation

Transform to position relative to camera.

Used here to strip out the translation portion of the view matrix to allow camera relative rendering of instances
