Syntax
vrdir2ori(d)
vrdir2ori(d,options)
Description
vrdir2ori(d) converts the viewpoint direction,
specified by a vector of three elements, to an appropriate orientation
(VRML rotation vector).
vrdir2ori(d,options) converts the viewpoint
direction with the default algorithm parameters replaced by values
defined in options.
The options structure contains the parameter epsilon that
