hi prof,

i have been trying to make the angle drawn as a dynamic pie for the angle instead of a hollow one, how do i filled the inside with a color ?

i read the reference but still i cant understand the logic of the polygon.

luckily i found


will study ur codes  ;D

but it seems a bit harder than i thought,

but i did it !!!

under constraints:

what does 2 lines do ? i completely cannot follow

c=cta2-(i-1)*dc; //  c = end of angle segment - (i-1)*a small segment ?
  if(c<-pi)c+=2*pi; // if c less than - Math.PI then c add one until 2*PI ?
