LYGIA Shader Library

Dependencies:

• lygia/math/saturate.glsl

Use:

<float> capusleSDF( in <vec3> pos, in <vec3> a, <vec3> b, <float> r )

Check it on Github

#ifndef FNC_CAPSULESDF
#define FNC_CAPSULESDF

float capsuleSDF( vec3 p, vec3 a, vec3 b, float r ) {
    vec3 pa = p-a, ba = b-a;
    float h = saturate( dot(pa,ba)/dot(ba,ba) );
    return length( pa - ba*h ) - r;
}
