Vertex normals

Hi Vtk experts…

When rendering a surface currently i see a banding effect and i believe it’s because Vtk is using face normals for the shading. Is there a way to generate per vertex normals? Many thanks.

Just pass your data through the vtkPolyDataNormals filter and make sure ComputePointNormals is on. This will add a normals attribute to your point data.

Thanks Andrew
