Detailed Description

An optional structure to construct a matrix for each particle during emissions. A particle can be represented as a single matrix. This gives the particles an orientation rather than just a simple position.

This allows transformation to be applied to the particles, such as rotation. If rpPRTSTDEMITTERPRTMTXFLAGSCNSMTX is set in the flag, then the prtCnsMatrix is applied to each particle during particle update.

If this structure is not present, then it assumes the particles will have just a position property.
