<h1>[name]</h1>
|

|
|
|
||
|
|
<div class="desc">Represents a spline.</div>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]( [page:Array points] )</h3>
|
||
|
|
|
||
|
|
<div>Initialises the spline with *points*, which are the places through which the spline will go.</div>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Properties</h2>
|
||
|
|
|
||
|
|
<h3>[property:Array points]</h3>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Methods</h2>
|
||
|
|
|
||
|
|
<h3>[method:null initFromArray]( [page:Array a] )</h3>
|
||
|
|
<div>
|
||
|
|
a — array of triplets containing x, y, z coordinates<br />
|
||
|
|
</div>
|
||
|
|
<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.
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<h3>[method:Vector3 getPoint]( [page:Integer k] )</h3>
|
||
|
|
<div>
|
||
|
|
k — point index
|
||
|
|
</div>
|
||
|
|
<div>Return the interpolated point at *k*.</div>
|
||
|
|
|
||
|
|
<h3>[method:Array getControlPointsArray]( )</h3>
|
||
|
|
<div>Returns an array with triplets of x, y, z coordinates that correspond to the current control points.
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<h3>[method:Object getLength]( [page:Integer nSubDivisions] )</h3>
|
||
|
|
<div>
|
||
|
|
nSubDivisions — number of subdivisions between control points. Default is *100*.
|
||
|
|
</div>
|
||
|
|
<div>
|
||
|
|
Returns an object with the two properties. The property .[page:Number total]</strong> contains
|
||
|
|
the length of the spline when using nSubDivisions. The property .[page:Array chunkLength]
|
||
|
|
contains an array with the total length from the beginning of the spline to the end of that chunk.
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<h3>[method:null reparametrizeByArcLength]( [page:Float samplingCoef] )</h3>
|
||
|
|
<div>
|
||
|
|
samplingCoef — how many intermediate values to use between spline points
|
||
|
|
</div>
|
||
|
|
<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>
|
||
|
|
<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>
