void TGLUtil::SetDrawColors ( const UChar_t rgbai[4] )

static

Set basic draw colors from 4 component 'rgba' Used by other TGLUtil drawing routines.

Sets basic (unlit) color - glColor and also GL materials (see OpenGL docs) thus:

diffuse : rgba ambient : 0.0 0.0 0.0 1.0 specular : 0.6 0.6 0.6 1.0 emission : rgba/4.0 shininess: 60.0

emission is set so objects with no lights (but lighting still enabled) are partially visible
