I would use this setup for geometry visualisation. Unit object
at origin with pigment{rgb 1}.
#declare c=50;
light_source{<0,1,-1>*100 rgb<0.3,1,0.3>*1 shadowless rotate c*z}
light_source{<0,1,-1>*100 rgb<0.3,0.3,1>*1 shadowless rotate (120+c)*z}
light_source{<0,1,-1>*100 rgb<1,0.3,0.3>*1 shadowless rotate (240+c)*z }
camera {
orthographic
location -10*z
}
