Two steps interactive modeling offline relaxation

Stitch Mesh Traditional work: Yarn loop This paper: Stich polygon wale edge course edge wale edge

Different Types Common types Special types

Details Borders Mismatched Wale Direction Cables

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 stitch mesh model mesh-based relaxation yarn curves yarn-level 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. 33 hours…
