How to get a silhouette?
Does anybody know how to get a silhouette of a shape? I successfully use HLR algorithms to get a 2D view of a model, and it seems that HLR can solve this problem too, but I don't understand how. I use HLRBRep_HLRToShape to filter results of Hide() operation, but how can I combine shapes from HLRToShape to obtain only a silhouette? May be there is some other solutions without HLR?
