screwy wireframes.

[Lisa Sobierajski Avila]

Hello Gala'Vi,

You have to change the amount of illumination of each type, not just the
color that the object reflects for that type of illumination. So you need
to do:

 cact->GetProperty()->SetAmbient(1.0);
 cact->GetProperty()->SetDiffuse(0.0);
 cact->GetProperty()->SetSpecular(0.0);
