Interactive Modeling• Labeling the Input Mesh Model
– labeled as either a wale edge or a course edge– User select borders as rows and they will be connected as wale edges
• Generating the Stitch Mesh– Tessellation according to the wale edges and the course edges
• Editing the Stitch Pattern– Edit the topology and attributes of the stitch mesh such as cables
Offline-Relaxation

Mesh-based Relaxation
• Use three types of spring forces– stretch– shear– a wale strut
Yarn-level Relaxation
• An anisotropic, biphasic force• Detection of Yarn Pull-through– Limit the max movement– Lod technic– Compute the safe bounds
Inspiration
• Use “CG” structure present the physical object• Combine physical and geometry function?
This paper builds the knitwear using stitch polygon instead of traditional yarn loops. The result is stunning but the method is too slow. It implies that we can try some computer graphics structure to simulate the complex objects.
