Members

points :Array.<Cartesian3>|Array.<Quaternion>

An array of control points.
Default Value: undefined

times :Number[]

An array of times for the control points.
Default Value: undefined

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], where t0 is the first element in the array times and tn is the last element in the array times.

findTimeInterval(time, startIndex) → Number

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.
