		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.

	<methods>
		<method name="create_convex_shape" qualifiers="const">
			<return type="Shape" />
			<argument index="0" name="clean" type="bool" default="true" />
			<argument index="1" name="simplify" type="bool" default="false" />
			<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.

		<method name="create_outline" qualifiers="const">
			<return type="Mesh" />
			<argument index="0" name="margin" type="float" />
			<description>
				Calculate an outline mesh at a defined offset (margin) from the original mesh.
				[b]Note:[/b] This method typically returns the vertices in reverse order (e.g. clockwise to counterclockwise).
