Smooth a bezier spline through prescribed points.

Smooth a bezier spline through prescribed points by solving a linear system. First we build a tridiagonal matrix and then we solve it using the Thomas algorithm. (FIXME: A tridiagonal matrix is easy to solve in O(n) but you cannot write a closed path as a tridiagonal. To solve closed paths we will have to use a different solver. Use the GSL?)

Here is an article that explains the math: http://www.particleincell.com/blog/2012/bezier-splines/

Basically we find all the ctrl1 points when we solve the linear system, then we calculate each ctrl2 from the ctrl1.

We build the linear system choosing for each segment of the path an equation among following 9 equations. "Straight" is a path that goes straight in to the knot (2nd derivative == 0 at the knot). "Smooth" means a path that goes smoothly through the knot, makes no corner and curves the same amount just before and just after the knot (1st and 2nd derivatives are constant around the knot.) "Keep" means to keep the control point as the user set it.

	start	end of path
1	straight	smooth
2	smooth	smooth
3	smooth	straight
4	keep	smooth
5	keep	keep
6	smooth	keep
7	keep	straight
8	straight	straight (yields a line)
9	straight	keep

The equations are (close your eyes):

\begin{eqnarray} 2P_{1,i} + P_{1,i+1} &=& K_i + 2K_{i+1} \label{1} \\ P_{1,i-1} + 4P_{1,i} + P_{1,i+1} &=& 4K_i + 2K_{i+1} \label{2} \\ 2P_{1,i-1} + 7P_{1,i} &=& 8K_i + K_{i+1} \label{3} \\ P_{1,i} &=& C1_i \label{4} \\ P_{1,i} &=& C1_i \label{5} \\ P_{1,i-1} + 4P_{1,i} &=& C2_i + 4K_i \label{6} \\ P_{1,i} &=& C1_i \label{7} \\ 3P_{1,i} &=& 2K_i + K_{i+1} \label{8} \\ 2P_{1,i} &=& K_i + C2_i \label{9} \end{eqnarray}

Some of these are the same and differ only in the way we calculate c2. (You may open your eyes again.)
