I am using vtkTraingleFilter to triangulate a vtkUnstructuredGrid.
My goal is to generate a smooth color map. My understanding is that I need more triangles to do this. For example a linear quadrilateral is rendered with two triangles, but I want it to be rendered with say, eight.
How do I achieve this? I was hoping to simply increase the number of triangles that vtkTriangleFilter generates but that doesn’t seem possible. (I am using Activiz btw).
Smoothing after triangulating is not what I want either, as I don’t want smoothing along cell boundaries.
