Map Generation

270M Tiles · IPC

[VIEW FULL PORTFOLIO DOC]

Featured Project

Massive Map Generation System ⭐ Initial implementation: 2023.07 ~ 2024.06

A large-scale tilemap generation system using partitioned parallel computation, an external agent process, and 2-channel PNG storage. The attached paper evaluates host responsiveness and storage trade-offs at 270 million tiles.

> Host Responsiveness: 51.26 FPS / worst frame 230.3 ms (IPC+Agent)

> Storage: 270 MB raw → 14.6 MB PNG (5.41% of raw size)

> Scale: 270M tiles (3000×3000×30); generation mean 22.467 s

Paper benchmark: i9-13900HX / 32 GB / RTX 4070 Laptop / Unity 6000.3.6f1 Mono; 2 warm-ups + 10 measured runs. Generation time excludes PNG saving, process startup, and IPC preparation; thermal conditions were uncontrolled. Job System + Burst generated faster (3.565 s); IPC+Agent achieved higher effective host FPS.

DX12 : Mesh Shader Pipeline 구현 ⭐ 2025.12 ~ Present

A Mesh Shader Pipeline built from scratch on DX12. A hybrid renderer where the IA path and the Mesh Shader path coexist in one renderer, extended with PBR & transparent rendering and a GPU measurement harness to directly measure and compare the two paths.

> Legacy IA Pipeline ↔ Mesh Shader Pipeline 하이브리드

> FBX + meshoptimizer 기반 Meshlet 생성 / AS 메시렛 컬링

> IA/MS 실측: 26개 환경 · 976개 촬영 위치 · 5,547개 유효 상태 (2026.10.19)

Visual Wave : VN Authoring Framework ⭐ 2025.05 ~ Present

A visual-novel authoring framework based on a frame-state execution model inspired by render state tables. Built as an engine-independent core + per-engine runtime + VS Code LSP, and validated for practicality on a commercial VN (ALCOHOL FREE).

> 대사 1자당 저장: 이전 노드그래프 약 30.0B → VW 약 4.7B (약 1/6)

> 상태 중복률: 85.4% → 0% (변화분만 기재)

> 상용 수준 VN 적용: 55 Scenes / 3,035 Commands / Godot 배경·대사 채널 실증

Paper comparison: previous node-graph tool 127 scenes / 2,734 frames vs. VW 55 scenes; normalized storage per dialogue character. This is a representation-size comparison, not a measured authoring-productivity gain.
