vtkAttributeMultiBlockSource: a multiblock source for attributes
Originally, the pipeline source for attributes was a vtkTrivialProducer
. The original source had only one output port (as opposed to the three output ports for model and mesh), which made it impossible to construct a runtime-configurable vtkSMTKSource
that could handle any resource. This MR introduces vtkAttributeMultiBlockSource
, a trivial producer derived from vtkMultiBlockDataSetAlgorithm
that has three output ports.
