Primitive prim = (CRef)ctx.GetInputValue(0,0);
PolygonMesh mesh(prim.GetGeometry(0,siConstructionModeAnimation));
CVertexRefArray outPoints = outMesh.GetVertices();
CVector3Array pos = outPoints.GetPositionArray();
I'm calling that block of code from inside of a customOperator, ok ?
There is an Envelope Operator below. It has some bones
so the mesh is being deformed by that bones.
PolygonMesh
- Secondary Shape Modeling
- Animation
- MyOperator
- EnvelopeOperator ->
-Shape Modeling
- Modeling
How to get result of "EnvelopeOperator" as an Array of absolute vectors, from
within "MyOperator" Update callback ?
Actually "pos " is filled with zeroes.
Hope, you get what I mean :)
Thanks
