Member Function Documentation

virtual void makVrv::MyParticleSystemModel::setModelInstance ( DtModelInstance * modelInstance )

virtual

Override setModelInstance to create the shader manager (or destroy it if the modelInstance is Null)

Reimplemented from makVrv::DtModel.

virtual void makVrv::MyParticleSystemModel::changeColorOverride	(	int	color,
		float	deltaChange
	)

virtual

This method has been added to the distributed interface of this object (through MyParticleSystemModel.ocdx).

When called, it calls the shader manager to perform the operation. The color parameter is 0, 1, or 2, to modify Red, Green, or Blue by deltaChange amount
