raymarcher infinite gyroid tunnels
A slow camera drift through infinite raymarched gyroid tunnels. Also the built-in default scene when no config file exists.
The scene itself is fixed: there is one tunnel geometry and no scene-selection key. You
steer the palette, fog, and pace. Default stops are
[[0.08, 0.10, 0.18], [0.55, 0.30, 0.15], [0.20, 0.35, 0.40]].
The two thermal knobs (render_scale, max_fps) are conservative by default. Raise them
if you have GPU headroom and want a sharper, smoother tunnel.
Properties
| key | type | default | meaning |
|---|---|---|---|
colors | array of [r,g,b] | indigo, amber, teal | 2 to 4 palette stops; the first also tints the fog. |
speed | float | `1.0` | Drift speed; `1.0` crosses one tunnel cell every ~18 s, `0` freezes the camera. Clamped to 0 to 10. |
fov_deg | float | `70.0` | Vertical field of view in degrees. Clamped to 30 to 110. |
fog | float | `1.0` | Fog-density multiplier. Very low values also reveal the far draw boundary, so they are not recommended. Clamped to 0 to 4. |
render_scale | float | `0.5` | Internal resolution as a fraction of the region; the host upscales. `0.5` costs a quarter of the rays of native. |
max_fps | float | `30.0` | Frame-rate cap. `0` means uncapped (compositor rate). Clamped to 0 to 240. |
every key is optional; omit it and the default applies. misspelled keys are silently ignored, so if a setting seems to do nothing, check the spelling against this table. colors are 0.0–1.0 float arrays.
