Returns an array of [Plane]s closely bounding a faceted capsule centered at the origin with radius [param radius] and height [param height]. The parameter [param sides] defines how many planes will be generated for the side part of the capsule, whereas [param lats] gives the number of latitudinal steps at the bottom and top of the capsule. The parameter [param axis] describes the axis along which the capsule is oriented (0 for X, 1 for Y, 2 for Z).

Returns an array of [Plane]s closely bounding a faceted cylinder centered at the origin with radius [param radius] and height [param height]. The parameter [param sides] defines how many planes will be generated for the round part of the cylinder.

Given a convex hull defined though the [Plane]s in the array [param planes], tests if the segment ([param from], [param to]) intersects with that hull. If an intersection is found, returns a [PackedVector3Array] containing the point the intersection and the hull's normal. Otherwise, returns an empty array.

Checks if the segment ([param from], [param to]) intersects the cylinder with height [param height] that is centered at the origin and has radius [param radius]. If no, returns an empty [PackedVector3Array]. If an intersection takes place, the returned array contains the point of intersection and the cylinder's normal at the point of intersection.
