From 2429fc2d3dea0d4e420a103a300e5226b06d1b67 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 11 Apr 2026 11:18:34 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=8E=A8=20Palette:=20Implement=20audio-rea?= =?UTF-8?q?ctive=20twilight=20glow=20for=20flora?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Visual Change: Trees and mushrooms now exhibit an audio-reactive, bioluminescent glow during the twilight and night phases of the day/night cycle. The glow fades in before sunset and fades out before dawn. The colors are species-specific and configured in `CONFIG.glowColorMap`. "Juice" Factor: The glow pulses organically to the low-frequency audio (kick drum) with a phase offset applied per-instance to prevent a mechanical, uniform pulse. This creates a breathing, living bioluminescent ecosystem. Technical: - Added `CONFIG.glow` settings (`startOffsetMinutes`, `endOffsetMinutes`, `glowPulseFrequency`, `glowPulseAmplitude`, `glowIntensityMax`, `glowColorMap`). - Updated `AtmosphereManager.getTwilightGlowIntensity` to respect the configured time windows. - Injected TSL logic into `mushroom-batcher.ts` and `tree-batcher.ts` to calculate phase-offset idle pulses mixed with audio reactivity, multiplied by the twilight window strength, and added to the emissive outputs of their materials.
