cross3d

Draw a 3D cross in an rgl scene

Draws a 3D cross or axis vectors in an rgl scene.

cross3d(centre = rep(0, 3), scale = rep(1, 3), ...)

`centre`	A scalar or vector of length 3, giving the centre of the 3D cross
`scale`	A scalar or vector of length 3, giving the lengths of the arms of the 3D cross
`...`	Other arguments, passed on to `segments3d`

Used for its side-effect, but returns (invisibly) a 6 by 3 matrix containing the end-points of three axes, in pairs.
