Owen Yuwono

Engineer working across distributed backend systems, real-time graphics and simulation, and blockchain infrastructure.

Repo What it does Stack
poseidon Real-time FFT ocean entirely on GPU: Tessendorf spectrum synthesis, compute-shader IFFT per frame, no CPU round-trip. WebGPU TSL Three.js FFT
minos Engine with Nanite-style virtualized geometry: per-cluster LOD, GPU-side culling, software raster for sub-pixel triangles. Rust Vulkan GPU-driven culling
demiurge Procedural planet from physics: tectonics drive uplift, uplift drives erosion, erosion and latitude drive climate and biomes. TypeScript WebGPU Three.js
tiamat Smoothed-particle hydrodynamics: density and pressure resolve from kernel-weighted neighbors, so splashes fall out of the solver. SPH fluid simulation particles
gaia Procedural grass rendered in the browser, fully deterministic. A seed reproduces the same field anywhere, no baked assets. Three.js deterministic
dryad Trees grown from planet physics and a seed. Structure follows simulated conditions, so parameters change the growth. Three.js simulation
apate Small learning repo for surface detail that isn't there: parallax occlusion mapping, its silhouette-clipped variant, and displacement. POM SPOM displacement
