Imagine converting any 50 pixel square brush to Turbo Silver. That's 2500 pixels, and that's a small brush. If you converted each pixel to a triangle of the right color, you'd have a 2500 triangle object. If you want the pixels to look square, you'd have a 5000 triangle object. Obviously, if the object has regions of similar color, you could convert them to polygons, then convert those to triangles, but that leads to polygons with more sides than VideoScape can handle, and many long thin triangles in Sculpt and Silver. To convert an N-sided polygon to triangles, you get N triangles. If the brush had jagged edges like a postage stamp, imagine how many triangles would result… InterFont lets you trace polygons over bitmaps, but only over bitmap fonts. We decided to make InterFont very specific, so that's why it doesn't load any IFF bitmap. If you have Calligrapher, you can load a brush into any character of a font, then trace that in InterFont… That works well. Illustrator has it easy, it sends objects to PostScript, which handles oodles of curves and line segments with ease, while 3D programs are more limited.
