a simple shadertoy

    Hey I'm learning how to port a shadertoy shader to jit.gl.pix I'm trying with this simple example https://www.shadertoy.com/view/lslyRH
    This is my patch, but nothing happen, can I know what I did wrong?
    and this is the code inside my jit.gl.pix I did :
    R=dim; u=cell-R/2; a=0.32; b=0.2; d=1.0125/32; c=159*d; fi=atan(u.x,u.y); col=vec(0.,0.,1.);
    for(i=0;i<pi;i+=pi/16) { temp1=i+c*fi-iTime; temp2=i+d*fi+iTime; col+=0.0005/abs(a+b*sin(temp1)*sin(temp2)-length(u)/(R.y/1.15)); } out=vec(col,1.0);
    Thank you very much!

      Hi Guillame! Just two things: - You mismatched the name of the context assigned to jit.gl.pix, there was a typo - in the codebox, atan must be replaced by atan2, since the behaviour of atan in gen is different
      Here's the correct patch:
      Cheers!
