// PILLAR SANCTUM — the raymarch engine's flagship: an infinite hypostyle
|
|
// hall of twisted columns, flown down one open lane. The ENTIRE scene is
|
|
// the scene_sdf subclass below: domain repetition puts a column in every
|
|
// cell, entasis bulge + a beat-pulsed twist shape it, floor and ceiling
|
|
// close the hall. Pattern taught: `scene_sdf` is the variant mechanism —
|
|
// override one function, inherit the whole marcher (march loop, normal,
|
|
// AO, soft shadow, cosine palette, fog).
