	</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.

		<constant name="ARRAY_TANGENT" value="2" enum="ArrayType">
			[PackedFloat32Array] of vertex tangents. Each element in groups of 4 floats, first 3 floats determine the tangent, and the last the binormal direction as -1 or 1.

			[PackedInt32Array] of integers used as indices referencing vertices, colors, normals, tangents, and textures. All of those arrays must have the same number of elements as the vertex array. No index can be beyond the vertex array size. When this index array is present, it puts the function into "index mode," where the index selects the *i*'th vertex, normal, tangent, color, UV, etc. This means if you want to have different normals or colors along an edge, you have to duplicate the vertices.
			For triangles, the index array is interpreted as triples, referring to the vertices of each triangle. For lines, the index array is in pairs indicating the start and end of each line.
