LYGIA Shader Library

mod2 (lygia/math/mod2)

Two dimensional modulus, returns the remainder of a division of two vectors. Found at in Mercury's library https://mercury.sexy/hg_sdf/

Use:

<vec2> mod2(<vec2> x, <vec2> size)

Check it on Github


#ifndef FNC_MOD2
#define FNC_MOD2
vec2 mod2(inout vec2 p, float s) {
    vec2 c = floor((p + s*0.5)/s);
    p = mod(p + s*0.5,s) - s*0.5;
    return c;
}

vec2 mod2(inout vec2 p, vec2 s) {
    vec2 c = floor((p + s*0.5)/s);
    p = mod(p + s*0.5,s) - s*0.5;
    return c;
}
#endif
