Height map shape resource for 3D physics. Height map shape resource, which can be added to a [PhysicsBody3D] or [Area3D]. Heightmap collision is typically used for colliding with terrains. However, since heightmaps cannot store overhangs, collisions with other structures (such as buildings) must be done with other collision shapes such as [ConcavePolygonShape3D]. If needed, "holes" can be created in an [HeightMapShape3D] by assigning very low points (like [code]-100000[/code]) in the desired area. [b]Performance:[/b] [HeightMapShape3D] is faster to check collisions against compared to [ConcavePolygonShape3D], but it is slower than primitive collision shapes such as [SphereShape3D] or [BoxShape3D]. Height map data, pool array must be of [member map_width] * [member map_depth] size. Number of vertices in the depth of the height map. Changing this will resize the [member map_data]. Number of vertices in the width of the height map. Changing this will resize the [member map_data].
