UxrSpline Class
Spline base class. We use splines to interpolate smoothly between a set of points. Interpolation can be done using the traditional t [0.0f, 1.0f] parameter and also distances to allow arc-length evaluation.

The UxrSpline type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | UxrSpline |
Properties
| Name | Description | |
|---|---|---|
 | ArcLength | Gets the actual length of the curve. |
| HasValidArcLengthData | Gets whether the spline contains valid data in order to evaluate the curve using arc length parametrization. |
| HasValidData | Gets whether the spline contains valid data in order to evaluate the curve. |
| UsePrecomputedSampleCount | Number of curve samples that are going to be pre-computed in order to enable arc length parametrization. This method must be called before creating the spline and will enable EvaluateUsingArcLength() calls. For short splines the default value is enough. For very long splines it may be required to increase the sample count. |
Methods
| Name | Description | |
|---|---|---|
| ComputeArcLengthSamples | Pre-computes a set of samples that will enable to evaluate the curve using arc-length parametrization. |
 | Evaluate(Single, Vector3) | Evaluates the curve |
| Evaluate(Single, Vector3, Vector3) | Evaluates the curve |
| EvaluateUsingArcLength(Single, Vector3) | Evaluates the curve using arc-length parametrization |
| EvaluateUsingArcLength(Single, Vector3, Vector3) | Evaluates the curve using arc-length parametrization |
