Simple library to generate rotation matrix around arbitrary axis

# matrix_rotate_arbitrary_axis #

Library to generate rotation matrix around arbitrary axis.

Original implementation of `RotationMatrix`

class (`matrix_rotate_arbitrary_axis.dart`

) by Glenn Murray.

## Usage #

If you want to apply rotation matrix to canvas in Flutter you can just call:

```
// Build a rotation matrix for rotations about the line through (a, b, c)
// parallel to [uUn, vUn, wUn] by the angle theta.
final rotationMatrix = RotationMatrix(a, b, c, uUn, vUn, wUn, angleInRadians);
final matrix = rotationMatrix.getMatrix();
canvas.transform(matrix2);
```

The parameters are:

- [a] x-coordinate of a point on the line of rotation.
- [b] y-coordinate of a point on the line of rotation.
- [c] z-coordinate of a point on the line of rotation.
- [uUn] x-coordinate of the line's direction vector (unnormalized).
- [vUn] y-coordinate of the line's direction vector (unnormalized).
- [wUn] z-coordinate of the line's direction vector (unnormalized).
- [theta] The angle of rotation, in radians.
