Procedural trees built on WebGPU and TSL — with real-time wind, MTree-style gravity sag, attractor-driven crown silhouettes, drag-to-bend branches, and pipeline-ready glTF export. No install. No build step. Native render path.
Procedural foliage, native to the browser.
A canonical tree-grow kernel with refCurve trunks, segment splits, and botanically-correct phyllotaxis — paired with attractor-driven crown seeding, post-pass gravity, three live ramp curves per level, and a Houdini-SOP-style typed-array pipeline that scales to 2M-vert trees.
From parametric growth to pipeline-ready export — every stage tuned for real-time foliage work in the browser.
Sketch the silhouette you want — a sphere, a teardrop, an upside-down umbrella — and the grow kernel biases branch direction, length, and phyllotactic placement to fill it. The crown emerges from the shape you draw, not from a fixed Weber-Penn envelope.
An MTree-style post-pass cascades rotations leaf-to-root, weighting each branch by length × radius². Heavy limbs droop, twigs settle, whorls stay level. Two sliders replace pages of hand-tuning.
Right-click any node and pull. Ancestors bend along the chain with soft-mass weights; release settles back with springy wind.
Three live Catmull-Rom ramps per level — length, randomness, startAngle — plus density and split-points. Five knots each. Drag a knot, the tree reshapes the moment you release.
Position-based dynamics on every skeleton node. Direction, gust, swirl, turbulence — bark sway driven from a typed-array SoA solver.
Compare LOD0–LOD3 in the same scene. Meshoptimizer where it pays, SimplifyModifier where it doesn't. Final LOD is an 8-tri crossed-quad billboard captured orthographically — drop-in for scattering tools past 100 m.
Wind vertex colors, pivot-painter UVs, named material slots, bounds metadata in extras. Drop-in for Unreal or Unity.
Radius, profile, knots, buttress, react-wood — drag and the trunk re-extrudes in 50 ms. Tubes-only fast path; foliage skipped while you sculpt.
Tree, chains, and tubes fan across hardwareConcurrency − 1 workers. Greedy bin-packing keeps each thread fed.
Switch between target, cursor, and bounding-center pivot modes — like Maya, Houdini, or Blender. Capture-phase orbit, no camera reset.
⌘K opens a fuzzy command bar across every slider, species, and toggle. Type two letters and you're there.
MeshPhysical with leaf translucency, tiling bark with normals, and a season palette that fades spring → summer → autumn → winter.
First load opens a tabbed species library — broadleaf, conifer, bush — with hand-shot thumbnails. Click a card, the tree applies. Dismissed for good after one click.
Every preset is a botanically-tuned bundle of phyllotaxis, branching, leaf shape, and seasonal palette. Pick one and start sculpting — or stay on Custom.
A Houdini-SOP-style flat-attribute pipeline. Five O(V) passes collapsed into one pool-fill loop. Tubes-only fast path for live scrubbing.
Five O(V) passes collapsed into one pool-fill loop. Pooled leaf slots. SoA skeleton with typed-array hot paths. The kernel that builds your tree is the kernel that scales it.
Vanilla ES modules, pinned Three.js from a CDN, a worker file, and a handful of textures. That's the whole app.
No install. Runs entirely in Chrome or Edge. Export straight to glTF — or fork the source and bend the kernel to your will.
