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.

Node that instances meshes into a scenario.
</brief_description>
<description>
MeshInstance is a node that takes a [Mesh] resource and adds it to the current scenario by creating an instance of it. This is the class most often used to get 3D geometry rendered and can be used to instance a single [Mesh] in many places. This allows to reuse geometry and save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance] instead.

This helper creates a [StaticBody] child node with a [ConvexPolygonShape] collision shape calculated from the mesh geometry. It's mainly used for testing.
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.

<description>
Returns the [Material] that will be used by the [Mesh] when drawing. This can return the [member GeometryInstance.material_override], the surface override [Material] defined in this [MeshInstance], or the surface [Material] defined in the [Mesh]. For example, if [member GeometryInstance.material_override] is used, all surfaces will return the override material.
