Hello, I am trying to transform a surface using a programmable filter, and I am unable to get the output to use the normals. Even the most basic filter:
output.PointData.append(inputs[0].PointData['Normals'], 'Normals') results in the mesh being copied but the normals not being used. The normals appear as a Data Array, but are not used in rendering. However, using the copy arrays option in the properties of the programmable filter lead to the normals being used correctly. What I would like to do is to apply an affine transformation on the point positions and normals (and visualize contours of a scalar field on a uniform, nonorthogonal parallelepiped grid), so I can't just use the copy arrays option. Thanks in advance! -Katie
