new Spline()
Creates a curve parameterized and evaluated by time. This type describes an interface
and is not intended to be instantiated directly.

Methods
-
evaluate(time, result) → Cartesian3|Quaternion
-
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]
, wheret0
is the first element in the arraytimes
andtn
is the last element in the arraytimes

findTimeInterval(time, startIndex) → Number
-
Finds an index
i
intimes
such that the parametertime
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:
