Dustmite
Graphics / Systems Programmer
I build performant graphics systems, simulations, and engines in C.
My focus is efficient and portable code that runs well on both high and low-end hardware.
Projects
3D Flow LeniaFinished
3D extension of Lenia with transport mechanics and real-time meshing, built on and for Windows XP-era hardware.
- CPU-only SIMD implementation
- Multithreaded, highly vectorized
- Reintegration tracking / advection
- Marching cubes meshing (4 views)

Untitled Game EngineIn Progress
The 3D game engine that brings high fidelity to low end-hardware.
- GPU-only path tracing UV lightmapper
- Parallax corrected reflection and indirect probes
- Acceleration structures (BVH) for both scene nodes and mesh faces
- Physics system with manifolds: PGS and Baumgarte Stabilization
- Collision with incremental hull: GJK, EPA, and triangle tests
C, OpenGL, GLSL, SDL2, Nuklear
Space SimulationIn Progress
3D space (surface + body) simulation with accretion and real-time lighting.
- GPU-only compute shader n-body simulation
- LBVH constructed from Morton codes
- Radix sort handles morton ordering
- Rayleigh / Mie scattering reflects on FFT water
- Perlin / fBM noise generates planet surfaces
C, OpenGL, GLSL, SDL2
Sarah (Chess Engine)Finished
Bitboard chess engine with handcrafted evaluation, tuning utilities, and extensive search heuristics.
- HCE with pawn hashing + lazy eval
- Search: RFP, Extensions, LMP, Futility, SEE, LMR, etc.
- Tuning utilities: SGDM(R) / ADAMW(R) / SPSA
- Corrective, continuation, capture, and regular history
C
Game EngineOn-Hold
3D game engine with a "precompute-everything" philosophy, bringing beautiful graphical fidelity to low-end hardware. Highly inspired by giallo and movement shooters.
- UV + volumetric lightmapper
- Material-based customizable rendering pipeline
- Skeletal animation system
- Collision system using precomputed jarvis marched hulls
- UI system: triangulated mesh elements, text rendering, and animations

PS1 Game DemoUnfinished
Movement FPS proof of concept for the PS1.
- Collision / movement system - fixed point math
- Map creation pipeline: game engine -> PS1
- Lightmapped + gouraud shaded
- Screen space fog inspired by Silent Hill
