Clean: remove duplicate and interior vertices (uses Bullet algorithm) Simplify: modify the geometry for further simplification (uses VHACD algorithm) In the editor, single convex hull now uses the clean option. Added a new editor entry to create a simplified convex hull, can be useful for creating convex hull from highly tessellated triangle meshes. Specific change for 3.x: Add support for Vector<Vector3> and PoolVector<Vector3> in the convex hull generator.

|
Mesh is a type of [Resource] that contains vertex array-based geometry, divided in [i]surfaces[/i]. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is preferred to a single surface, because objects created in 3D editing software commonly contain multiple materials.

|
Calculate a [ConvexPolygonShape] from the mesh.
|
|
If [code]clean[/code] is [code]true[/code] (default), duplicate and interior vertices are removed automatically. You can set it to [code]false[/code] to make the process faster if not needed.
|
|
If [code]simplify[/code] is [code]true[/code], the geometry can be further simplified to reduce the amount of vertices. Disabled by default.
