Executive Summary
A personal project aiming to build a suite of software leveraging procedural approaches through a fully self-built software stack. Using Revion (GPU GUI) and Cognet (node graph engine) as a common foundation, the project expands into domains where node-based workflows excel: 3D modeling, task automation, video editing, music production, and more. Additionally, by integrating Web GIS and a P2P-based daily management system, the goal is to create an ecosystem that visualizes and manages real-world events.

Livu — Housing BIM Platform
Role: Application Layer / BIM platform supporting the entire housing lifecycle
One Model for Life — Homeowners, architects, builders, and real estate agents all view, interact with, and update the same model. From design to construction, living, and resale, the entire lifecycle of a home is connected through a single model.
Core Concept
- Beginners assemble rooms like puzzle pieces
- Professionals fine-tune materials and structures in detail
- Different depths of operation, but the same underlying model
- The model persists beyond design, living alongside the house
Key Features
- Intuitive floor plan editor accessible to everyone
- Real BIM data underneath (construction-ready quality)
- 3D/VR property tours
- Property marketplace (buy/sell/rent)
- Model inheritance (transfer to next owner upon sale)
Technical Foundation
- UI / Node graph foundation via Revion + Cognet
- Geometric operations and BIM modeling via Geolis
- Geographic placement and sunlight simulation via Sora integration
Revion — Declarative GPU GUI Framework
Role: Foundation Layer / Rendering foundation for all procedural software
A declarative GUI framework that renders entirely on the GPU. By maximizing GPU parallel processing capabilities, it achieves high performance even with complex node graphs and real-time previews.
Key Technologies
- GPU-accelerated rendering pipeline
- Declarative UI paradigm
- Custom shader-based text and vector rendering
- Immediate mode / Retained mode hybrid architecture
Cognet — Node Graph Engine
Role: Logic Layer / The heart of procedural software
A node graph engine that serves as the common foundation for all procedural software: BIM, task automation, video editing, music production, and more.
Key Technologies
- Directed acyclic graph (DAG) execution engine
- Lazy evaluation & caching mechanism
- Type-safe node connection system
- Plugin architecture for domain-specific nodes
Integration Points
- Provides node editor UI integrated with Revion
- Connects nodes across domains (geometry / task execution / video processing / audio processing, etc.)
Geolis — CAD Kernel
Role: Geometry Layer / Computation engine for 3D modeling
A CAD kernel for geometric operations and shape modeling. Developed within the visual environment built with Revion + Cognet, allowing visual verification of algorithm behavior during implementation.
Key Technologies
- B-Rep (Boundary Representation) modeling
- NURBS curves and surfaces
- Boolean operations (Union, Intersection, Difference)
- Mesh generation and tessellation
Development Approach
- Implement Geolis features as Cognet nodes
- Immediately verify implemented features in the visual environment
Sora — Web GIS
Role: Geospatial Layer / Location information visualization foundation
A geographic information system running on the web. Integrated with Livu, enabling architectural models to be handled within geographic context.
Key Technologies
- WebGL-based map rendering
- Vector tile processing
- Geospatial data format support (GeoJSON, Shapefile, CityGML)
- Coordinate system transformations
Integration with Livu
- Geographic coordinate placement of BIM models
- Relationship analysis with surrounding buildings and terrain
- Sunlight simulation, view analysis
Lattice — P2P Cross-Platform Daily Management
Role: Infrastructure Layer / Visualize and manage reality
A cross-platform app leveraging P2P and CRDT with zero running costs. Achieves serverless data synchronization for daily task and project management. Provides a system to visualize and manage real-world events.
Key Technologies
- P2P networking (libp2p or similar)
- CRDT for conflict-free synchronization
- Cross-platform (Desktop, Mobile, Web)
- Zero server cost architecture
Vision
- Graph-based visualization of tasks and schedules
- Dependency management between projects
- Structured management of all life and work events
