Hi Connie, << one more question: can you give me an example of a "deformation" one might use? >> Sure. A deformation would be a bend, stretch, squash, etc., on a *global* level (affecting the entire mesh), or on a *local* level using selection sets of vertices. Any modification of the geometry, other than *transformations* (move, rotate, etc.) could be considered a deformation of that geometry, I guess. And you can perform *linear* or *non-linear* deformations, whereby the deformation maintains a proportional relationship between the vertices as they're relocated….or not,….hence, a non-linear deformation. An example would be the classic character animation concept & technique of "squash & stretch", as pioneered primarily by Disney's staff in the 20's-30'. A simpler example would be to simply bend a cylindrical mesh into a letter "c". Does that help ? Regards, BILL
