Volume raymarching

Function of the form f(x,y,z,t) — use variabile x,y,z,t in the selected domain: float radius = 0.4 + 0.05 * sin(t * 0.7); // helix radius varies float twistSpeed = 1.0; // rotation speed float helixHeight = 1.0; // vertical scale // Rotate coordinates over time float angle = twistSpeed * t + z * 3.0; float hx1 = cos(angle) * radius; float hy1 = sin(angle) * radius; float hx2 = cos(angle + 3.1416) * radius; // opposite strand float hy2 = sin(angle + 3.1416) * radius; // Distance to each strand's center line float d1 = length(vec2(x - hx1, y - hy1 * helixHeight)); float d2 = length(vec2(x - hx2, y - hy2 * helixHeight)); // Gaussian falloff for smooth density (0<f<1) float density1 = exp(-20.0 * d1 * d1); float density2 = exp(-20.0 * d2 * d2); float pulse = 0.5 + 0.5 * sin(t * 3.0); return clamp((density1 + density2) * pulse, 0.0, 1.0); Domain (min — max for each spatial variable). Values are mapped to [-1,1] internally. Alpha scale (max value = no transparency) Quality (raymarching steps) Time control Anti-banding: jitter
