Methods

ClosestParameter

#
public double ClosestParameter(Locus point)
Get the parameter on the line closest to a point.
Parameters:
point (Locus)Point to approach.
Returns: Parameter on line.

ClosestPoint

#
public Locus ClosestPoint(Locus point)
Project a point onto the line.
Parameters:
point (Locus)Point.
Returns: Point on plane.

CrossingPoint

#
public bool CrossingPoint(InfinitePlane slice, out double t)
Find the parameter on the line at which it intersects a given slice.
Parameters:
slice (InfinitePlane)Slice to intersect.
t (out double)Parameter on line.
Returns: True if line and slice intersect.

CrossingPoint
