Summary

This tutorial repository addresses the implementation of a high-performance, scalable "infinite canvas" for front-end applications. It targets developers seeking to understand and build complex 2D rendering engines, offering a deep dive into modern web graphics technologies, GPU acceleration, and advanced UI patterns. The benefit lies in a structured learning path to create feature-rich, non-linear design or creative tools.

How It Works

The project explores advanced 2D rendering using @antv/g-device-api for WebGL1/2 and WebGPU abstraction. It employs an Entity-Component-System (ECS) architecture via Becsy for high scalability and performance. Core techniques include Signed Distance Field (SDF) rendering for shapes, GPU-accelerated text and Bezier curves, and tile-based rendering inspired by industry leaders like Figma. Future iterations aim for a Rust-based rendering backend.

Quick Start & Requirements

Installation requires pnpm. Navigate to a lesson directory (e.g., packages/lesson_001) and run pnpm run dev to start the development server. Alternatively, build the site with pnpm run build and run its dev server. No specific hardware or OS prerequisites beyond modern browser support for WebGL/WebGPU are detailed.

Highlighted Details

• Comprehensive exploration of rendering techniques: SDF, GPU acceleration, tile-based rendering, hand-drawn styles.
• Covers a vast array of canvas functionalities: scene graphs, transformations, event systems, UI integration, performance optimization, CRDT-based collaboration, and AI integration.
• Modular, lesson-based structure guides users through complex topics from basic shapes to advanced text rendering and image processing.
• Future roadmap includes a Rust rendering backend, leveraging wgpu, rough-rs, and y-crdt.

Maintenance & Community

This repository appears to be a personal tutorial project. No specific details regarding maintainers, community channels (e.g., Discord, Slack), or formal roadmaps are provided in the README.

Licensing & Compatibility

The provided README does not specify a software license. This lack of licensing information presents a significant barrier for evaluating commercial use or derivative works.

Limitations & Caveats

The project is described as having "relatively low" completion, indicating it is under active development and may not be production-ready. The absence of a stated license is a critical caveat for adoption.
