| 18 | <h3>[name]( [page:Array points] )</h3>
|
|---|
| 19 |
|
|---|
| 20 | <div>Initialises the spline with *points*, which are the places through which the spline will go.</div>

| 28 | <h2>Methods</h2>
|
|---|
| 29 |
|
|---|
| 30 | <h3>.initFromArray( [page:Array a] )</h3>
|
|---|
| 31 | <div>
|
|---|
| 32 | a â array of triplets containing x, y, z coordinates<br />
|
|---|
| 33 | </div>
|
|---|
| 34 | <div>Initialises using the data in the array as a series of points. Each value in *a* must be another array with three values, where a[n] is v, the value for the *nth* point, and v[0], v[1] and v[2] are the x, y and z coordinates of that point n, respectively.
|
|---|
| 35 | </div>
|
|---|
| 36 |
|
|---|
| 37 | <h3>.getPoint( [page:Integer k] )</h3>
|
|---|
| 38 | <div>
|
|---|
| 39 | k â point index
|
|---|
| 40 | </div>
|
|---|
| 41 | <div>Return the interpolated point at *k*.</div>
|
|---|
| 42 |
|
|---|
| 43 | <h3>.getControlPointsArray( )</h3>
|
|---|
| 44 | <div>Returns an array with triplets of x, y, z coordinates that correspond to the current control points.
|
|---|
| 45 | </div>
|
|---|
| 46 |
|
|---|
| 47 | <h3>.getLength( [page:Integer nSubDivisions] )</h3>
|
|---|
| 48 | <div>
|
|---|
| 49 | nSubDivisions â number of subdivisions between control points. Default is *100*.
|
|---|
| 50 | </div>
|
|---|
| 51 | <div>Returns the length of the spline when using nSubDivisions.</div>
|
|---|
| 52 |
|
|---|
| 53 | <h3>.reparametrizeByArcLength( [page:Float samplingCoef] )</h3>
|
|---|
| 54 | <div>
|
|---|
| 55 | samplingCoef â how many intermediate values to use between spline points
|
|---|
| 56 | </div>
|
|---|
| 57 | <div>Modifies the spline so that it looks similar to the original but has its points distributed in such way that moving along the spline it's done at a more or less constant speed. The points should also appear more uniformly spread along the curve.</div>
|
|---|
| 58 | <div>This is done by resampling the original spline, with the density of sampling controlled by *samplingCoef*. Here it's interesting to note that denser sampling is not necessarily better: if sampling is too high, you may get weird kinks in curvature.</div>
