Method Detail

bezier [line 110]

double bezier(
double
$t, double
$p1, double
$p2, double
$p3, double
$p4)

Calculates a Bezier point, this function must be called for BOTH X and Y coordinates (will it work for 3D coordinates!?)

Return: The bezier value of the point t between $p2 and $p3 using $p1 and $p4 to calculate control points

Parameters:

double	`$t`	—	A position between $p2 and $p3, value between 0 and 1
double	`$p1`	—	Point to use for calculating control points
double	`$p2`	—	Point 1 to calculate bezier curve between
double	`$p3`	—	Point 2 to calculate bezier curve between
double	`$p4`	—	Point to use for calculating control points

controlPoint [line 85]

double controlPoint(
double
$p1, double
$p2, double
$factor, [
$smoothFactor = 0.75])

Calculates a Bezier control point, this function must be called for BOTH X and Y coordinates (will it work for 3D coordinates!?)

Return: P1 mirrored in P2 by Factor

Parameters:

double	`$p1`	—	1st point
double	`$p2`	—	Point to
double	`$factor`	—	Mirror factor, 0 returns P2, 1 returns a pure mirror, i.e. P1 on the exact other side of P2
	`$smoothFactor`	—

[ Top ]

mid [line 54]

double mid(
double
$p1, double
$p2)

Return the average of 2 points

Return: The average of P1 and P2

Parameters:

double	`$p1`	—	P1 1st point
double	`$p2`	—	P2 2nd point

[ Top ]

mirror [line 69]

double mirror(
double
$p1, 
$p2, [double
$factor = 1], double
$o2)

Mirrors P1 in P2 by a amount of Factor

Return: mirrored in $p2 by Factor

Parameters:

double	`$p1`	—	1st point, point to mirror
double	`$o2`	—	2nd point, mirror point
double	`$factor`	—	Mirror factor, 0 returns $p2, 1 returns a pure mirror, ie $p1 on the exact other side of $p2
	`$p2`	—
