Methods

evaluate(time, result) → Cartesian3|Quaternion

Core/Spline.js 54

Evaluates the curve at a given time.

Name	Type	Description
time	Number	The time at which to evaluate the curve.
result	Cartesian3 | Quaternion	optional The object onto which to store the result.

Returns:

The modified result parameter or a new instance of the point on the curve at the given time.

Throws:

• DeveloperError : time must be in the range [t0, tn], where t0 is the first element in the array times and tn is the last element in the array times.

findTimeInterval(time, startIndex) → Number

Core/Spline.js 68

Finds an index i in times such that the parameter time is in the interval [times[i], times[i + 1]].

Name	Type	Description
time	Number	The time.
startIndex	Number	The index from which to start the search.

Returns:

The index for the element at the start of the interval.

Throws:

• DeveloperError : time must be in the range [t0, tn], where t0 is the first element in the array times and tn is the last element in the array times.
