vtkpolygonalsurfacepointplacer用法 vtkPolygonalSurfacePointPlacer是VTK(The Visualization Toolkit)中的一个点定位器(Point Placer)。它可以用于将点放置在多边形表面(例如VTK中的PolyData对象)上。 使用vtkPolygonalSurfacePointPlacer需要先创建一个vtkPolyData对象,然后将其作为参数传递给vtkPolygonalSurfacePointPlacer的...

I have a VTK 6.3 program that I have distilled down to the listing below. When I run it, the rendered polygon is not correct. It should be a quadrilateral with another attached quadrilateral on the side, not this wacky thing: It looks as though the polygon triangulation is in error, and...
vtkDelaunay2D 错误 Edge not recovered, polygon fill suspect vtkDelaunay2D 在设定SetSourceData边界处理凹多边形时,不稳定,有概率会出现“Edge not recovered, polygon fill suspect”错误,这是因为边界内的部分三角形没有生成。 最终采用CGAL的三角形剖分
