BSpline
=======

[](#bspline)

A simple and fast uniform-knot BSpline curve implementation in PHP. Usually, BSpline's basis function is defined recursively by De Boor's algorithm. But this library includes pre-calculated uniform-knot BSpline basis. Thus, the library works very fast.

Usage:

```
$spline = new BSpline($points);
$spline->calcAt($t, $degree);
// or
$spline->run($degree);

```

- *points* : The array of points. Array of any dimensional vector is OK.
- *degree* : The degree of BSpline curve. *degree* should be 2,3,4 or 5.
- *t* : The parametor of BSpline. t is in \[0,1\]. If t = 0 then returns first point of *points*. If t = 1 then returns last point of *points*.

Example:

```
$points = [[1,2],[2,3],[3,4]];
$spline = new BSpline($points);
for($t = 0; $t calcAt($t, 3);
}
// or
$sPoints = $spline->run(3);

```
