Not Telling
After extensive searches i havn't been able to find a solution.
Working in 2d, i want to find the intersection point of a line with a catmull rom spline curve.
At the moment, i'm dividing the curve segment into numerous straight lines and performing line to line intersection tests with each.
It works, but isn't very efficient and not very accurate, depending on how many sub divisions of the curve i use.
Does anybody know a much more efficient and accurate solution to this problem.
Any help would be much appreciated.

It was felt that a single level didn't convey enough of the game to players but that a 3 level demo provides enough variation to allow players to better judge the game.
The demo features levels, 1 , 7 and 12 from the full version of the game.
The game has had numerous updates, extensive playtesting and game balancing since my initial v1.0 demo.
About The Game
Zytron II is a twin stick, scrolling shoot em up for Windows PC Computers and is the sequel to my 1990 shoot em up for the Commodore 64 home micro, Zytron Megablast.
Sold through the classic UK magazine of the time, Zzap64.
The game is typical of scrolling shoot em ups of that era and will be familiar to anyone who's played such classics as, Armalyte, R-Type or Gradius ( Nemesis ).
The aim of the game is simple enough, blast anything and everything in your path to make your way to the last level and destroy the end of game boss.
