Description
• a bearing and a distance from a known point and
an offset point.
To calculate the direction, the distance and the 3D
coordinate differences between a known point and
a given arc.
The arc can be defined using
• three points.
• a radius to two known points.
• a radius and two tangents, each of it defined by
a point and the intersection point of the tangents.
• the length of an arc and two tangents, each of it
defined by a point and the intersection point of
the tangents.
• the length of a chord and two tangents, each of
it defined by a point and the intersection point of
the tangents.
To calculate the direction, the distance and the 3D
coordinate differences between a known point and
the current position.
Points with full coordinate triplets and position only
points can be used.
To calculate the position of new points using
