NPM

#pragma glslify: superformula require('glsl-superformula') 
 
vec2 doModel(vec3 p) {
    float id = 1.0;
    float d = length(p);
    float theta = atan(p.y / p.x);
    float phi = asin(p.z / d);
 
    float r1 = superformula(theta, 8.060.0100.030.01.01.0);
    float r2 = superformula(phi, 2.010.010.010.01.01.0);
 
    vec3 q = r2 * vec3(r1 * cos(theta) * cos(phi), r1 * sin(theta) * cos(phi), sin(phi));
    d = d - length(q);
 
    return vec2(d, id);
