API function: algo.convexDecomposition
Use this feature to create a new set of convex meshes that approximate the selected mesh.
An example of use is convex mesh colliders.
The feature is driven by two parameters:
- The maximum number of convex meshes to be created
- The maximum number of vertices per convex mesh
This example shows how you can use this feature to solve 3D physics problems:
Without processing, classic 3D physics engines can't simulate the movement of the rings. Because of concavity, the pillars and the rings require specific processing:
- The base must be decomposed into a set of four convex meshes:
- Each ring must be decomposed into enough convex meshes for the simulation to look realistic:
Tip
A convex decomposition with V vertices and T triangles always satisfies the Euler characteristic:
You can use this formula to show the triangle count to users.
V = 2 + T/2
