UtilIntersectCircleSphere Method (Vector3, Vector3, Double, Vector3, Double, Double)

Calculate the intersection points of a circle (in a given plane) and a sphere surface (using supplied epsilon as a tolerance in equality).

Namespace:  Demo3D.Common
Assembly:  Demo3D.Common (in Demo3D.Common.dll) Version: 15.0.2.11458
Syntax
C#
Copy
public static Vector3[] IntersectCircleSphere(
	Vector3 circleCenter,
	Vector3 circleNormal,
	double circleRadius,
	Vector3 sphereCenter,
	double sphereRadius,
	double epsilon
)

Parameters

circleCenter
Type: Microsoft.DirectXVector3
Center of the circle.
circleNormal
Type: Microsoft.DirectXVector3
Normal to the plane that the circle is in.
circleRadius
Type: SystemDouble
Radius of the circle.
sphereCenter
Type: Microsoft.DirectXVector3
Center of the sphere.
sphereRadius
Type: SystemDouble
Radius of the sphere.
epsilon
Type: SystemDouble
Tolerance for floating point comparisons.

Return Value

Type: Vector3
null meaning no intersections (includes case where circle is contained in the sphere, or circle is completely on the surface), or a Vector3[2], containing the two intersections (which could be the same).
