## Description¶

This node returns the intersection circle of the two input spheres. A sphere intersects another sphere in a circle, the node returns the radius, normal and center of the the intersection circle.

## Illustration¶

Orange point is the center of the blue intersected circle.

## Inputs¶

**Sphere 1 Center**- The location of the center of the first required sphere.**Sphere 1 Radius**- The radius length of the first required sphere.**Sphere 2 Center**- The location of the center of the second required sphere.**Sphere 2 Radius**- The radius length of the second required sphere.

## Outputs¶

**Circle Center**- The location of the center of the intersected circle.**Circle Radius**- The radius length of the intersected circle. if this values is zero and*Is Valid*is True, that means that the spheres are touching at the*Circle Center*.**Is Valid**- A boolean which is True if an intersection was found, and False otherwise.
