Procedural Stitching Mechanics

Update on Feb 12

Prototype 1: Vertices Dragger (representing a place for the needle to pierce)

The assets (represented by the capsules in the video) can be placed near the vertices that you want to drag.

Then in the run time, you can drag the vertices by mouse or simply move the capsule.

Prototype 2: Rope

The physics is not reliable, so I programmatically made the rope attached to the vertices draggers when they collide.

There is also a check mechanism to tighten the wire between two draggers.

Prototype 3: Implement on Any Mesh

I imported a teddy bear model that I made. I put a tear on the model for stitching.

Combining the two prototypes above, we get this rough stitching mechanism.
