PROMT
Build a single-file interactive 3D web experience called "Volcano Island." using Three.js (WebGL), all procedural, zero external assets. A tiny cartoon tropical island with an active volcano sits on a round glass plate in the middle of an ocean block, and the user triggers eruptions and changes the sky.
LOOK AND FEEL
- Bright, playful low poly style with flat colors, soft shading and a clean toy-like look.
- A soft gradient sky background that changes with the chosen sky color, with slowly drifting puffy low poly clouds.
- Serif title "Volcano Island." top left with a small italic hint under it describing the interaction (tap the crater to erupt, tap the slope for lava, tap the sea for waves, drag to orbit).
- A round, shallow, frosted glass plate with a thin white rim, seen from a three-quarter top view, with a soft shadow.
- Small refined UI. Bold but friendly, like a limited edition desk toy.
THE ISLAND
- A square block of ocean with a clean cutaway side showing deep water layers, a bright turquoise surface with darker blue wave patches, foam edges and sparkles.
- A rounded, organic-shaped island in the center with a pale sand ring, a bright green grass band, a few low poly palm trees and small ferns.
- A tall dark gray volcano cone with faceted slopes, a glowing yellow-orange crater and several lava channels running down the sides that glow orange.
- A thin white smoke column rising from the crater at idle, drifting in the wind, plus a faint warm glow in the crater.
- Everything built from simple low poly shapes with flat shading and strong emissive glow on the lava, all procedural.
ERUPTION
- A large orange-red pill button "Erupt!" at the bottom center (also Space bar) triggers a full eruption: the crater flashes, a thick dark ash column shoots upward, glowing orange lava blobs and colored fireballs arc out in all directions and fall back onto the island and into the sea with small splashes.
- The slopes light up with fresh bright lava streams that cool from yellow to orange to dark red to black rock.
- The island shakes slightly, palm trees sway, the camera does a small shake and the sky tint warms for a few seconds.
- Steam rises where lava reaches the water, and the sea glows near the shore.
- After the eruption the volcano slowly calms back to a gently smoking idle.
- Tap or click the crater to erupt, tap a slope to start a lava flow from that point, tap the water to make a ripple and a small wave.
SKY AND CONTROLS
- Sky swatches along the bottom left: day (clear blue), sunset (purple to orange gradient), dusk (gray blue) and night (dark with stars and a strong lava glow). Switching one smoothly transitions sky color, light direction, shadows and glow.
- Top right buttons: "Room view" (wider camera) and "Settings".
- Settings panel: eruption power slider, smoke density slider, auto-rotate toggle, sound on or off.
- Keyboard: Space to erupt, 1 to 4 to switch the sky, R to reset the island.
LIFE AND ANIMATION
- Idle animations: smoke drift, pulsing lava glow, swaying palms, gentle ocean waves, birds circling and sparkling foam.
- Soft squash and stretch on the island, lava blobs and ash clouds during the eruption.
SOUND AND POLISH
- Low rumbles, explosive booms, crackling lava, hissing steam and ocean waves synthesized with WebAudio (no files), tied to the eruption intensity.
- 60 fps, adaptive pixel ratio, filmic tone mapping, soft shadows and strong bloom on lava and fire glow.
- Smooth camera orbit with inertia and an optional gentle auto-rotate.
- Works on desktop and mobile touch. Clean, commented code in one HTML file with constants grouped at the top. Prompt by @bluumik , posted on X on 2026-10-30. x.com/bluumik/status/2116023184524763484 . Copies include this credit. Original prompt, credited
