PouleyKetchoupp 240c33708c Options to clean/simplify convex hull generated from mesh
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.

<brief_description>
A [Resource] that contains vertex array-based geometry.
</brief_description>
<description>
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.

<description>
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.
