Spc.Rotate: Rotate an object by c(ax,ay,az) in the x y and z planes,...

In JerBoon/vecspace: Build a Hierarchy of Objects in 3D Euclidean (x,y,z) Space

Description

Rotate an object by c(ax,ay,az) in the x y and z planes, about the point c(x,y,z) Uses the right-hand coordinate system (this is the only functin in this package which is handed in this way). Rotates about first the x axis, then y, then z. This operation is not commutable (i.e. if you rotate by the various angles about first z, then x then y, you'd get a different result).

Usage

Spc.Rotate(object, pivot.point = NA, pivot.angle)

Arguments

object	The object (elementary or compound) to be rotated
pivot.point	Vector of the point in space to rotate about. Defaults to NA, which causes it to pivot about the object's own centre
pivot.angle	Vector of angles to rotate about (x,y,z) - in degrees

Value

The same object, but with all appropriate spacial points updated accordingly
