Three coordinated changes:
1. nightPaletteNew.cloud: void -> raised (slightly lighter than
sky) so clouds have contrast against the new-moon sky
2. nightPaletteFull.cloudShadow: panel -> void so cloud undersides
fade into the night sky, while the lit topsides (border) stand
out clearly
3. getNightColor() now keeps 'light' (moonlight) bright and only
partially darkens sky/bg. The previous version squashed
everything toward black, killing cloud structure.
Shader side:
- max(0.15, uDayProgress) keeps a baseline moonlight tint on the
lit side of clouds even when uDayProgress happens to be 0
- The final darken pass is now driven by nightFactor (sunAlt-based)
instead of the unreliable uDayProgress
Inserted two extra palette entries around the sunset transition:
- alt -0.262 (-15deg): already full-night (void), so ~1h after
sunset the sky is properly dark instead of still 11% into the
long -5.7deg -> -90deg void ramp
- alt -0.087 (-5deg): dusk anchor (panel) — was at -0.1
- alt 0.087 (+5deg): morning anchor (blood) — was at 0.15
Net effect: +5deg to -15deg transition (≈80 minutes of real time
in summer) now sweeps through golden -> rust -> panel -> void
instead of golden -> rust -> panel -> panel/void.
Three fixes:
1. getColor() switched from 'sunPos.altitude > 0' to
'> sunPalettes[0].alt' (-pi/2). The day palette interpolates
through twilight to deep-below-horizon, so an hour after sunset
(sunAlt ~ -15deg) we now stay on the day palette and get the
intended dark 'panel' colour instead of switching to the moon
palette immediately.
2. getNightColor() now actually applies MIN_NIGHT_BRIGHTNESS via
shiftColor toward black (the old 'brightness' var was unused
dead code).
3. applyWeatherTheme() cuts the weather tint by up to 70% at
night, so a 'cloudy' theme no longer washes the night sky with
the brighter weather sky colour.
- Cruise altitude 2.6 -> 2.0 (just above cloud ceiling y=1.5,
gives the 'just above the clouds' airliner feel)
- Expose __currentSunAlt (radians) from animate() so the
renderer can tell night from day without misreading
realDayProgress (which mixes pre-dawn + post-sunset hours)
- Replace (1 - uDayProgress) star gate by smoothstep over uSunAlt:
nightFactor = 1 when sun is well below horizon, 0 when above
- Widen sky band so stars are visible from the horizon upward
(cockpit-perspective frame is mostly below rd.y=0.3)
Raymarches a horizontal cloud layer (28 steps, 4-octave 3D fBm).
Camera path is sinusoidal in altitude so the view dips into the
cloud deck at intervals for a 'fly through the edges' feel.
Density threshold from weather: sunny -> sparse, stormy -> overcast.
Renderer is selected via CONFIG.renderer ('clouds2d' or 'clouds3d').
- Remove all hardcoded fallback hex/rgb values
- Skip draw until __currentPalette is published by parent
- applyWeatherTheme now also mixes cloudShadow (was dropped)
The 2D WebGL renderer now creates its own <canvas> overlay inside
the target element, instead of expecting the target to already be a
canvas. This fixes 'canvas.getContext is not a function' when the
target is a <div>.
