For the time being we don't support writing a description for those, preferring having all details in the method's description. Using self-closing tags saves half the lines, and prevents contributors from thinking that they should write the argument or return documentation there.

<description>
|
|
Returns an array with 6 [Plane]s that describe the sides of a box centered at the origin. The box size is defined by [code]extents[/code], which represents one (positive) corner of the box (i.e. half its actual size).

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

Given a convex hull defined though the [Plane]s in the array [code]planes[/code], tests if the segment ([code]from[/code], [code]to[/code]) 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.
