## Values

| Name | Value | Description |
| --- | --- | --- |
| None | 0 | No intersections. Either because radius is too small or because circle plane is parallel but not coincident with the intersection plane. |
| Tangent | 1 | Tangent (one point) intersection. |
| Secant | 2 | Secant (two point) intersection. |
| Parallel | 3 | Circle and plane are planar but not coincident. Parallel indicates no intersection took place. |
| Coincident | 4 | Circle and plane are co-planar, they intersect everywhere. |
