#### 10.2.19 PaintFacet

• PaintFacet( <facets list>, <color+i*(non oriented 0/1)>, < (backculling 0/1)+i*contrast> ).
• Description: that command returns the <facets list> after adding in the imaginary part of each constant jump that is located between the facets, a <color> (in fact this is the color+2). If the argument <non oriented> is $1$, then the front and back of the facets are not distinguished. If the argument <backculling> is $1$ then the non visible facets are eliminated. The argument <contrast> is a positive number or zero that permmits or not to accentuate the color contrast between the facets, with the value $0$ the color will be solid.
• That command is used by the drawing macro DrawFacet.
