Nawashiro — Thu, 12 Sep 2024 00:44:30 +0000

PNG Museum and Engineer Assembly co-hosted a hackathon in VRChat.

This document summarizes the slides I presented at the hackathon in text format.

Overview

VRChat is a metaverse platform. You can participate using HMD, PC, or smartphone.

The worlds in VRChat can be controlled using a C#-like programming language called Udon.

The Udon Zettelkasten System I created this time is a VRChat gimmick that allows you to implement a dynamic model and build a Zettelkasten using Udon.

The "Thing" You Often See in Crime Dramas

The thing where you stick notes on the wall and connect them with strings to organize.
Zettelkasten - A method of organizing notes.
Often seen in note-taking apps like Obsidian.
I wanted to realize that "thing" within VRChat!

Useful in Various Use Cases

Discussion events like Philosophy Cafes
Virtual meetings within VRChat
Idea generation and brainstorming

Udon Zettelkasten System

Developed a PKM gimmick that can be used within VRChat!

(PKM = Personal Knowledge Management)

Feature Introduction ①

Adding notes: You can specify the title, color, text, and links to other notes.
Editing/Deleting notes: When you Use a note, details are displayed, and you can edit or delete it.
Data saving: Save to a notepad, etc., and resume editing even if the instance changes.

Feature Introduction ②

Multilingual support: ChatGPT did it overnight, so accuracy is 🥴
- English/Esperanto/Japanese/Korean/Russian/Simplified Chinese/Traditional Chinese
- Automatically switches based on the system's time zone.
Calculation limits: Enabled by default
- As the number of notes increases, the amount of calculation increases exponentially, so limits are set when a certain amount is exceeded.
- Instead of calculation errors, the operation becomes lighter.
Export function for LLM:
- Export function to read as materials for NotebookLM, etc.

Other Initiatives

First attempt at shaders!
- I wrote the ground shader for the first time.
- I wanted to make the ground reflect beautifully like Salar de Uyuni
- Implemented Fresnel reflection
Booth store opened!
- Udon Zettelkasten System will be sold as an asset (sales started at the time of writing this article!).
