Make vtkContourWidget Object Work On Webassembly Page

I had found a crash bug when use vtkContourWidget by webassembly in the post Crash Bug About vtkOpenGLPolyDataMapper::UpdateShaders In vtkAbstractWidget.As we know, SetResolveCoincidentTopologyToPolygonOffset for mapper can make web page crash, related post: The Interfaces In VTK Can’t Be Used With Webassembly. After reading the source code of vtkOrientedGlyphContourRepresentation::vtkOrientedGlyphContourRepresentation(), we know Read more…

Get Normals Of Points By vtkPolyDataNormals

The post is related to The Example About vtkPolyDataNormals. If you want to use vtkPolyDataNormals to compute the normals of points, it’s better to set variable Splitting false. #include <vtkVersion.h> #include <vtkSmartPointer.h> #include <vtkSurfaceReconstructionFilter.h> #include <vtkProgrammableSource.h> #include <vtkContourFilter.h> #include <vtkReverseSense.h> #include <vtkPolyDataMapper.h> #include <vtkProperty.h> #include <vtkPolyData.h> #include <vtkCamera.h> #include <vtkRenderer.h> Read more…
