Question

I'd like to just display the polygons in their specified colour with no shading, is this possible? I've tried setting each of ambient, specular, diffuse etc. to 1 and the others to 0 with no luck.

Was it helpful?

To do so specify actor.GetProperty().LightingOff() on the respective vtkActor. See e.g. http://www.vtk.org/doc/nightly/html/classvtkProperty.html

Based on the vtk Pyramid the effect can be seen in the following example
