a simple shadertoy
May 16 2018 | 1:53 pm
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!
