3 Presets and a Transform

Well, after just losing my previous post due to ICQ's default action of 'open link in current window' I'll start this post now. (again, grrr)

Well, after reviewing the past few weeks of exam period, I've discovered that it's been the most productive MD session in, well.. a long time.

I've come up with a few families of presets, (in order of how cool I think they are):
- Spokes
- Chaotic Paint
- Slow Thing

I had an idea of an 'axis transform' code, which you can use on any existing code, (with a little modification).
Basically, it allows you instead of using x,y,dx,dy, you get a set vx,vy,dvx,dvy for a set of axes inclined at at angle vang.
You can set this to any variable you can dream of, and get some pretty good effects (i've just done some basic ones here (prefixed by @xis).
 Also the 'bare-bones' of the code is in 'axis transform'.

Anyway, let me know what you think.
Yours truly,

Does anyone know how dx, dy are derived from the values of sx & sy? ie: dx = dx + f(x,cx,sx); dy = dy + f(y,cy,sy); With these I'll have finished my transformation 'library'. I've tried using these f's: dx = dx + (x-cx)*(sx-1); dy = dy - (y-cx)*(sy-1); they look close, but at large values (eg, 0.5, 2) they don't correspond to the equvalent scale values. (they underapproximate) Any help would be greatly appreciated. Telek Sterling Dilettante Extraordinaire
