Godot-docs: Explain the difference between trimesh and convex body

[rcorre]

The MeshInstance menu has these options:

• Create trimesh static body
• Create convex static body
• Create trimesh collision sibling
• Create convex collision sibling

What do trimesh and convex mean in this context?
How should I choose one or the other?
Is one more precise and one more performant?

A trimesh is going to follow closer to your original mesh. Including concave sections. While a convex static body is going to encapsulate the exterior of the mesh, but will flatten out concave sections.

here is a useful image demonstrating the difference.

Your right, this should be documented somewhere.

Wow, looking back on this 18 months later like "did I really not know that?" :laughing:
