// CLASS DESCRIPTION (MPxDeformerNode)
|
|
//
|
|
// MPxDeformerNode allows the creation of user-defined deformers. A deformer
|
|
// is a node which takes any number of input geometries, deforms them and
|
|
// places the output into the output geometry attribute.
|
|
//
|
|
// For more information, please see the built-in documentation
|
|
// in MPxDeformerNode.cpp.
