[vtkusers] Problem about lighting

[Lisa S. Avila]

Hello Miyashita,

It is possible you have a buggy OpenGL driver. In general you should set 
Ambient = 1.0 and Diffuse and Specular = 0.0 to effectively turn off 
lighting for an object. The color of the object will then be based on the 
Color or scalar values passed through a lookup table.
