		A 3D height map shape used for physics collision.
	</brief_description>
	<description>
		A 3D heightmap shape, intended for use in physics. Usually used to provide a shape for a [CollisionShape3D]. This is useful for terrain, but it is limited as overhangs (such as caves) cannot be stored. Holes in a [HeightMapShape3D] are created by assigning very low values to points in the desired area.
		[b]Performance:[/b] [HeightMapShape3D] is faster to check collisions against than [ConcavePolygonShape3D], but it is significantly slower than primitive shapes like [BoxShape3D].

		<method name="get_max_height" qualifiers="const">
			<return type="float" />
			<description>
				Returns the largest height value found in [member map_data]. Recalculates only when [member map_data] changes.

		<method name="get_min_height" qualifiers="const">
			<return type="float" />
			<description>
				Returns the smallest height value found in [member map_data]. Recalculates only when [member map_data] changes.
