How to draw OUTLINES on 3D shapes? [REPOST]
From reading Mr. Fairley's reply to my earlier post, I realized that I had not been entirely clear, so here is (I hope) a clearer statement of the problem. How can I get Mathematica to draw 3D shapes (specifically, spheres and cylinders) as "filled in outlines"? By "outline" I mean that of the 2D representation (as shown on the computer screen) of the 3D object. For example, whereas a 2D representation of a cylinder would look something like __________ ()_________) the *outline* of this representation would look like __________ (__________) Similarly, for a cube, a 2D representation would be ______ / /| /_____/ | | | | | | / |_____|/ and the outline of this representation would be ______ / | / | | | | / |______/ It's important to note that I'm not referring to the silhouette (which would be, for example, the 2D figure obtained by filling in the outline above: //////// ///////// ///////// ///////// //////// ) but to the actual 1-dimensional countour we use to represent the *boundary* of the silhoutte.
