mikejuk writes: Simulating cloth is big business — how else can CGI characters get to wear any clothes? Now, as well as simple fabrics, graphics designers can have knitwear on their virtual clothes racks.
Cem Yuksel of the University of Utah, Jonathan Kaldor of Facebook, and Steve Marschner and Doug James of Cornell have tackled the problem of rendering knitted material. Rather than trying to create a full 3D model of the knitted surface the approach is to use a model of a single stitch, render it and then use it to tile the surface. The 3D model has an extra stitch mesh added to it and a pattern of stitches is built up for each of the appropriate tiles to fill.The process of rendering the final knitted surface has to be done off-line and it is slow. This means that, at the moment at least, it can't be easily used for real-time games, but for CGI movies it is just another batch rendering process to add to the mix. paper.pdf
