# learning jitter expressions

I try to learn jitter expressions because there the core of jitter . Can you recommend good books (maths or other anything) that can help me to understand these “mysterious” expressions.

the easiest way is to create a new object and start typing either “cv.jit.___” or “jit.___” and select any of the object expressions that appear in the drop-list. then (in edit mode) alt+click the object and learn more about, copy it, edit it-whatever you please.

Thanks , I know there plenty of articles but the problem is that i don’t have a knowledge base and when i want to put my ideas in practice i realize that i’m lost.

The forum is like a candy store. A lot of tastes hide the ingredients :)

I speak about expressions like :

expr ” pow(min(norm[0] , sqrt(norm[1])) , 2.0)”

or

expr sin(norm[0]*(2*PI))*sin(norm[1]*(2*PI))

or

DEGTORAD, RADTODEG, E, LN2, LN10, LOG10E, LOG2E,

I was not very good of math ( I know basic geometry) so i tried to find some good books. I need to study analytic geometry or matrices? Can you recommend some books that will illuminate me ?

Thanks
