LYGIA Shader Library

aspect (`lygia`/`space`/`aspect`)

Fix the aspect ratio of a space keeping things squared for you.

Use:

<vec2> aspect(<vec2> st, <vec2> st_size)


#ifndef FNC_ASPECT
#define FNC_ASPECT
vec2 aspect(vec2 st, vec2 s) {
    st.x = st.x * (s.x / s.y);
    return st;
}
#endif

Use:

<float2> aspect(<float2> st, <float2> st_size)


#ifndef FNC_ASPECT
#define FNC_ASPECT

float2 aspect(float2 st, float2 s) {
    st.x = st.x * (s.x / s.y);
    return st;
}

#endif
