int points_from_plucker
(
	Vector **point_one,
	Vector **point_two,
	const Vector *plucker_line
);

PARAMETERS

Vector **point_one: Pointer to the first point.
Vector **point_two: Pointer to the second point.
const Vector *plucker_line: The plucker line to derive points from.

DESCRIPTION

Given *plucker_line, will find two points in 3-D space, homogenized to w = 1.0. The approach used is to asssume that the line crosses one of the axes, (X,Y,Z), resulting in both points having a value of 1.0 or -1.0 for one of the other three values.

RETURNS

ERROR if plucker_line is not a valid plucker line or on allocation failure. NO_ERROR otherwise.

plane_from_lines_as_points, plane_from_plucker_lines, distance_between_lines_as_points

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
