详细描述

DayNight module — a time-of-day cycle that drives the sun, sky and light.

Advances a 24-hour clock (configurable speed) and, each frame, repositions the directional sun to match the current solar elevation / azimuth. A procedural sky cubemap (sky gradient + sun disc + night stars) is generated on demand and registered as the 3D IBL environment so both the skybox angle and the reflected sky follow the sun as time flows.

At night the module can switch between complementary lighting systems, each implemented as a pool of Light3D entities:

  • moonlight : a cool, low directional light from the moon direction
  • starlight : a faint, slightly-blue ambient that softens the dark
  • fire : a warm point light at a caller-provided campfire position
  • fireflies : a set of warm, gently-drifting point lights

Usage from script: daynight.setTimeOfDay(12.0); // solar noon daynight.setSpeed(1.0); // 1 real hour per simulated hour daynight.setNightLight("fireflies", true); // each frame before gfx.render3D(): daynight.update(dt, gfx); camera.setAmbient(daynight.getAmbientR(), ...);
