IntersectionTests

Methods

<static> grazingAltitudeLocation

Provides the point along the ray which is nearest to the ellipsoid.

Parameters:

Name	Type	Description
ray	Ray	The ray.
ellipsoid	Ellipsoid	The ellipsoid.

Throws:

• DeveloperError : ray is required.
• DeveloperError : ellipsoid is required.

Returns:

Cartesian The nearest planetodetic point on the ray.

<static> rayEllipsoid

Computes the intersection points of a ray with an ellipsoid.

Parameters:

Name	Type	Description
ray	Ray	The ray.
ellipsoid	Ellipsoid	The ellipsoid.

Throws:

• DeveloperError : ray is required.
• DeveloperError : ellipsoid is required.

Returns:

Array An array of one or two intersection scalars for points along the ray or undefined if there are no intersections.

<static> rayPlane

Computes the intersection of a ray and a plane.

Parameters:

Name	Type	Description
ray	Ray	The ray.
planeNormal	Cartesian3	The plane normal.
planeD	Number	The distance from the plane to the origin.

Throws:

• DeveloperError : ray is required.
• DeveloperError : planeNormal is required.
• DeveloperError : planeD is required.

Returns:

Cartesian3 The intersection point or undefined if there is no intersections.
