Hi,
thanks, I tried this way, now I see the outline of my object :
http://farm2.static.flickr.com/1295/715403834_b2cb845d85.jpg?v=0
But there's still one problem, inside this outline, it's drawn in black
(or any color) by
modelMt :
SimpleMaterialPtr modelMT = SimpleMaterial::create();
modelMT->setDiffuse(Color3f(0,0,0));
And if instead of this material I put a transparent one, then I have all
the shape in green
due to the inkSHL chunk.
Is there any way to have the outline drawn, and the part inside the
contour transparent?
Regards,
Adrien
