# Liquid Glass Effects Brainstorming Session
|
|
|
|
**Session Date:** December 19, 2024
|
|
**Facilitator:** Mary (Business Analyst)
|
|
**Topic:** Liquid glass effects for Vite app
|
|
|
|
## Session Setup
|
|
|
|
**Topic:** Liquid glass effects for Vite application
|
|
**Goal:** Generate creative approaches and implementation strategies
|
|
**Output:** Structured document for future reference
|
|
|
|
## Session Context
|
|
|
|
**Project:** Excalidraw monorepo enhancement
|
|
**Tech Stack:** React 19 + TypeScript + Vite 5.x + SCSS/CSS modules
|
|
**Goal:** Implement liquid glass effects for UI components
|
|
**Focus:** Implementation approaches and visual effect analysis
|
|
**Approach:** Technical Deconstruction
|
|
**Reference:** `liquid-glass-react` library analysis
|
|
**Implementation Goal:** Enhance existing Excalidraw components with optical glass effects
|
|
|
|
## Session Notes
|
|
|
|
### Technical Deconstruction: Liquid Glass Visual Properties
|
|
|
|
**Core Optical Phenomena Identified:**
|
|
1. **Refractive Index Simulation** - Light bending through glass material
|
|
2. **Edge vs Center Distortion** - More warping at edges, blur in center
|
|
3. **Layered Frosting Effects** - Varying opacity and texture layers
|
|
4. **Spatial Layering** - Glass components exist ON TOP of content, not embedded
|
|
5. **Morphic Interaction** - Water droplet-like deformation on hover/interaction
|
|
6. **Chromatic Aberration** - RGB channel displacement for realistic light splitting
|
|
|
|
**Implementation Techniques:**
|
|
- **Displacement Mapping** - Shader-based refraction simulation (performant alternative to ray tracing)
|
|
- **RGB Channel Aberration** - Per-channel displacement intensity control
|
|
|

|
|
- **RGB Channel Aberration** - Per-channel displacement intensity control
|
|
|
|
**Target Component:** AppMainMenu.tsx - MainMenu wrapper with nested items
|
|
|
|
### Dynamic Glass Container Architecture
|
|
|
|
**Unified Surface with Dynamic Separation:**
|
|
- Default state: Single glass container wrapping entire MainMenu
|
|
- Interactive state: Individual menu items become detachable "droplets"
|
|
- Surface tension physics: Items float back to main container
|
|
- onClick integration: Droplet separation triggers menu actions
|
|
|
|
**Technical Approach:** Three.js for shader-based displacement and physics simulation
|
|
**Browser Compatibility:** WebGL fallback considerations needed
|
|
|
|
### Generated Ideas - Dynamic Glass Behavior
|
|
|
|
**Container Architecture:**
|
|
1. **Unified Glass Wrapper** - Single container around entire MainMenu
|
|
2. **Mercury-like Physics** - Quick, fluid return behavior for separated items
|
|
3. **Surface Tension Model** - Items connected by invisible elastic forces
|
|
|
|
**Droplet Separation Triggers:**
|
|
1. **Hover Proximity** - Items bulge outward as cursor approaches
|
|
2. **Click Preparation** - Item separates slightly before click registers
|
|
3. **Drag Interaction** - Physical pulling of items away from container
|
|
4. **Active State Separation** - Highlighted items naturally separate
|
|
|
|
### Generated Ideas - Implementation Progression
|
|
|
|
**Phase 1: CSS-Based Prototype**
|
|
1. **Basic Glassmorphism Wrapper** - backdrop-filter, blur, transparency layers
|
|
2. **Simple Displacement Effect** - CSS transforms and distortions
|
|
3. **Hover Interactions** - transition-based morphing effects
|
|
4. **Integration with AppMainMenu** - maintain existing functionality
|
|
|
|
**Phase 2: Three.js Library Exploration**
|
|
1. **React Three Fiber** - React bindings for Three.js
|
|
2. **Drei Components** - Pre-built effects and helpers
|
|
3. **React Spring Three** - Physics-based animations
|
|
4. **Shader Material Libraries** - Glass/liquid effect implementations
|
|
|
|
**Prototype Development:**
|
|
- Working CSS glass effect for AppMainMenu component
|
|
- Three.js integration roadmap with specific libraries |
