Method GetPointAtDistance

Namespace

GeometryHelper.Geometry

Assembly

GeometryHelper.dll

GetPointAtDistance(double)

Gets the point at a distance measured from the origin along the ray direction.

public GeoPoint3 GetPointAtDistance(double distance)

Parameters

distance double

The distance from the origin.

Returns

GeoPoint3

The point at that distance.

Remarks

Because the direction is normalized, the parameter and the arc length are the same number here. A negative distance extrapolates behind the origin, off the ray itself; this matches GetPointAtParameter(double), which likewise follows the infinite carrier rather than clamping. Ask IsPointOn(GeoPoint3) when the question is whether a position is actually on the ray.
