  3. Two steps offline relaxation interactive modeling

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

  5. Different Types Common types Special types

  6. Details Mismatched Wale Direction Borders Cables

  7. 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

  8. Offline-Relaxation stitch mesh model yarn curves mesh-based relaxation yarn-level relaxation

  9. Mesh-based Relaxation • Use three types of spring forces • stretch • shear • a wale strut

  10. Yarn-level Relaxation • An anisotropic, biphasic force • Detection of Yarn Pull-through • Limit the max movement • Lod technic • Compute the safe bounds

  11. 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…
