egui-advanced-patterns

What problem does it solve?

This Skill provides a comprehensive set of advanced patterns for building sophisticated egui applications, enabling developers to implement smooth animations, custom GPU rendering, scene navigation, and scalable architectures with less boilerplate.

Core Features & Use Cases

• Animation patterns: built-in and manual per-frame approaches, including staggered and spring mechanisms for responsive UIs.
• Custom wgpu rendering (PaintCallback): integrate bespoke GPU rendering into egui pipelines for effects like 3D visualization and custom shading.
• Scene and zoom/pan canvas: built-in scene handling with pan and zoom controls and transformation utilities.
• Level-of-detail (LOD) and performance helpers: strategies like frame caching and culling to keep large apps responsive.
• Large app architecture patterns: modular patterns for scalable, maintainable egui applications drawn from Rerun.
• Reusable widget patterns: widget composition and data-driven UI building for complex UIs.

Quick Start

Start by implementing a small egui app that uses built-in animations and a basic PaintCallback to render a simple scene, then expand to add pan/zoom, staggered elements, and a minimal LOD strategy.
