I just brushed up my trig, maybe matrix maths will be next…
How does one use/install a JS library. I saw some JS coded matrix
functions once but these are genuine classes. If I install will it
work in QC. I guess if I want matrix maths I should go to GLSL but my
progress is slow with the CoreImage Filter so far.

Incidentally, there's a JavaScript library called Sylvester

that replicates many of the built-in OpenGL and GLSL matrix and
vector functions. You can poke around in the code and see how they
work.

would this JS function be correctly called Normalize or Clamp?
function Normalize (a)
{
b = Math.min (1, Math.max(0, a));
return b

Does normalizing typically map a whole (defined) range of values to
[0,1] or just Filter/Clamp values to [0,1]? I read the OpenGL doc
(GLSL-Land-spec-4.00.8) but I'm none the wiser.
