A spline that uses piecewise linear interpolation to create a curve.
alias LinearSpline
- The options object takes the following properties
- {Number[]} options.times An array of strictly increasing, unit-less, floating-point times at each point.
The values are in no way connected to the clock time. They are the parameterization for the curve.
- {Cartesian3[]} options.points The array of Cartesian3 control points.
exception {DeveloperError} points.length must be greater than or equal to 2.
exception {DeveloperError} times.length must be equal to points.length.
