[vtkusers] rendering a coloured model

[Alex Malyushytskyy]

Depending on your situation different approaches might be required.
As for coloring none of them require textures.

You need to decide which data set type you are going to use first.
In case of irregular mesh you would probably want to use vtkPolydata dataset.

in general color can be set per actor, per element or per node

Color can be specified directly or obtained using lookup table and scalar array.
For example direct color (as RGB) per element:
