Am looking with great intensity and interest at a simulation of wrinkling trousers and trying to understand how to represent (in the simplest way possible) the creasing at the rear of the knee and the way the wrinkles compress and concertina like an accordion.
In an attempt to find illumination, I place the following into a good image search: NASA EVA (extravehicular activities), as that is what I need to mimic. Amongst the gorgeous pictures taken in orbit, the obsessive catalogue of mechacal arms and space gear, are EVAs of a different kind, namely EVA Mendes, EVA Longoria (a little too much of the latter, and not enough of the former). Oh, and EVA Green.
The technical issue (getting back to the aforementioned knee) is that there’s no easy way to represent thickness and volume of the cloth, given that all the simulation models assume cloth to be a thin, single sided mesh. When I say thickness, I mean a thin piece of cloth or fabric sitting on top of many padded layers. Answer: it aint easy!
