「How do you create the figures in your course notes?」
Answer:「Right now, the process for creating figures is really a labor of love. I start out in a 3D modeler (Luxology"s modo), where I create the initial geometry, typically as a subdivision surface with a coarse control cage. I render this geometry out in several layers (silhouette, shadows, contour lines, etc.) and then trace over them by hand or using Image Trace in Illustrator. From there I choose the colorization, line styles, etc. For some of the figures I also write custom code (e.g., to construct a certain geometry). Someday I"d love to write a more automated tool, but there are only so many hours in the day! If you think you have a good way of attacking this problem, I"m all ears.」
