how did any of this work? match other CellSet file layouts. ??? compile in CUDA. unit tests. also only serial. make error message accurate Well, this compiles and works now. Did it ever? use CellShapeTagGeneric UnitTest matches previous changes. whoops Fix linking problems. Need the same interface as other ThreadIndices. add filter test okay, let's try duplicating CellSetStructure. okay inching... change to wedge in CellSetListTag Means changing these to support it. switch back to wedge from generic compiles and runs remove ExtrudedType need vtkm_worklet vtkm_worklet needs to be included fix segment count for wedge specialization need to actually save the index for the other constructor. specialize on Explicit clean up warning angled brackets not quotes. formatting
