Distance (Sphere)

Menu Path : Operator > Math > Geometry > Distance (Sphere)

The Distance (Sphere) Operator takes a sphere and a position and calculates:

• The closest point on the sphere to the position.
• The distance between the closest point and the position.

This Operator doesn't support spheres that have scale axis of different lengths (ellipsoids). If you use an ellipsoid as an input, this Operator uses its longest axis to define the sphere.

Operator properties

Input	Type	Description
Sphere	Sphere	The Sphere this Operator evaluates. The point this Operator returns (closestPosition) is the closest point on this Sphere to Position.
Position	Position	The Position this Operator evaluates. The point this Operator returns (closestPosition) is the closest point to Sphere from this position.

Output	Type	Description
closestPosition	Position	The position of the closest point on Sphere to Position.
distance	float	The distance from Position to closestPosition. If Position is outside Sphere, this value is positive. If Position is inside Sphere, this value is negative.
