Build this concept image as a AAA-quality, fully explorable Three.js/WebGPU world. Use the image as the primary art-direction reference.
Create a large, seamless desert oasis tree village centered around a crystal-clear turquoise lagoon. Ancient massive trees grow directly from rocky islands and shoreline areas, with believable roots, trunks, branches, dense foliage, vines, and vegetation. Integrate handcrafted tree homes naturally into the trees: wooden rooms, balconies, spiral/tree stairs, rope bridges, suspended walkways, lanterns, railings, docks, lookout platforms, thatched roofs, linen shade canopies, hanging baskets, and small gathering spaces.
The environment should feel physically plausible rather than theme-park-like. Tree architecture must appear structurally attached to trunks and branches. Bridges should sag naturally. Wood, bark, rope, stone, fabric, sand, vegetation, and water need high-resolution PBR materials with realistic roughness, normal variation, imperfections, weathering, and contact detail.
Make the lagoon a centerpiece: transparent tropical water, believable depth gradient, refraction, reflections, underwater visibility, caustics, shoreline wetness, gentle ripples, shallow sand, submerged rocks, and small waterfalls feeding the lagoon. Surround it with pale desert sand, rocky cliffs, palms and sparse oasis vegetation fading into a huge arid landscape.
Include multiple distinct tree houses based on the reference: large primary tree house, medium nest-style house, small perch, multi-level canopy house, and a house/platform extending over the water. Connect them into one coherent village using elevated bridges, ground trails, docks, and shoreline paths.
Lighting: cinematic late-afternoon/golden-hour daylight, physically based sky and atmosphere, soft volumetric haze, long natural shadows, subtle reflected turquoise light from the lagoon, warm lantern interiors, excellent exposure and tone mapping. No fantasy glow except believable lantern lighting.
Player should spawn near the lagoon at human eye height and freely explore in first person with smooth walking, sprinting, jumping, stairs, bridges, platforms, buildings, docks, shoreline, shallow water, and swimming. Use realistic collision and movement. Make distant views equally convincing from elevated tree houses.
Prioritize AAA visual fidelity + 60 FPS-class optimization: LODs, instancing, frustum/occlusion strategies, texture compression, baked/static lighting where appropriate, efficient foliage, pooled effects, sensible shadow distances, aggressive asset preloading, and no first-interaction hitching.
No sound/audio yet. No gameplay objectives or HUD clutter. The goal is a beautiful, photorealistic, peaceful world that feels like a real place someone could spend hours exploring.
