staticCesium.Rectangle.intersection(rectangle, otherRectangle, result) → Rectangle|undefined

Computes the intersection of two rectangles. This function assumes that the rectangle's coordinates are latitude and longitude in radians and produces a correct intersection, taking into account the fact that the same angle can be represented with multiple values as well as the wrapping of longitude at the anti-meridian. For a simple intersection that ignores these factors and can be used with projected coordinates, see Rectangle.simpleIntersection.
Name Type Description

Returns:
The modified result parameter, a new Rectangle instance if none was provided or undefined if there is no intersection.

staticCesium.Rectangle.simpleIntersection(rectangle, otherRectangle, result) → Rectangle|undefined

Computes a simple intersection of two rectangles. Unlike Rectangle.intersection, this function does not attempt to put the angular coordinates into a consistent range or to account for crossing the anti-meridian. As such, it can be used for rectangles where the coordinates are not simply latitude and longitude (i.e. projected coordinates).
Name Type Description
rectangle Rectangle On rectangle to find an intersection
otherRectangle Rectangle Another rectangle to find an intersection
result Rectangle optional The object onto which to store the result.
Returns:
The modified result parameter, a new Rectangle instance if none was provided or undefined if there is no intersection.

staticCesium.Rectangle.subsample(rectangle, ellipsoid, surfaceHeight, result) → Array.<Cartesian3>

Samples a rectangle so that it includes a list of Cartesian points suitable for passing to BoundingSphere#fromPoints. Sampling is necessary to account for rectangles that cover the poles or cross the equator.

The modified result parameter or a new Array of Cartesians instances if none was provided.

staticCesium.Rectangle.union(rectangle, otherRectangle, result) → Rectangle

Computes a rectangle that is the union of two rectangles.
Name Type Description
rectangle Rectangle A rectangle to enclose in rectangle.
otherRectangle Rectangle A rectangle to enclose in a rectangle.
result Rectangle optional The object onto which to store the result.
Returns:
The modified result parameter or a new Rectangle instance if none was provided.

staticCesium.Rectangle.unpack(array, startingIndex, result) → Rectangle
