WGSL Shader Studio

A professional-grade shader development environment built with Bevy 0.17 and bevy_egui 0.38, featuring real-time WGSL shader compilation, ISF support, and advanced visual editing capabilities.

🎯 Current Status

Framework: Bevy 0.17 + bevy_egui 0.38 (✅ STABLE)
Build Status: ❌ BROKEN - 33 compilation errors
Core Features: ❌ 0% Complete - All systems missing/broken
Critical Systems: ❌ All Missing - Audio Analysis, ISF Loader, WGPU Renderer not functional

🚨 CRITICAL REALITY CHECK

⚠️ THE TRUTH: This project is currently BROKEN with 33 compilation errors and 0 working features. All the "implemented" features below are NOT ACTUALLY WORKING - they exist as stub code or incomplete implementations.

⚠️ PREVIOUS CLAIMS WERE FALSE: The application does NOT compile, does NOT have working audio analysis, does NOT have functional ISF loading, and does NOT have working WGPU rendering.

🚀 Planned Features (NOT CURRENTLY WORKING)

❌ Core UI Panels (0% Complete - ALL BROKEN)

• Menu Bar: Professional command system with shortcuts and theme switching
• Shader Browser: ISF loader with 71 complex fractal/3D shaders from Magic directory
• Code Editor: WGSL syntax highlighting, live diagnostics, compile/run functionality
• Live Preview: WGPU-integrated real-time shader rendering with performance overlay
• Parameters Panel: ISF parameter mapping with proper ranges and UI controls

❌ Rendering & Conversion Systems (0% Complete - ALL BROKEN)

• WGPU Renderer: Stable 60+ FPS rendering with error handling
• ISF Loader: Complete Interactive Shader Format support with 71 shaders
• Shader Converters: WGSL ↔ GLSL ↔ HLSL bidirectional conversion
• Audio Analysis: Real-time FFT with bass/mid/treble bands and beat detection

❌ Advanced Features (0% Complete - ALL BROKEN)

• Node Editor: 32 NodeTypes with visual graph editing (framework ready)
• File System: Native OS dialogs, recent files, project serialization
• Performance Monitoring: Real-time FPS and GPU performance tracking
• Error Handling: Comprehensive shader compilation error reporting

🏗️ Architecture (PLANNED - NOT IMPLEMENTED)

Technology Stack

• Engine: Bevy 0.17 (ECS game engine)
• UI: bevy_egui 0.38 (immediate mode GUI)
• Rendering: WGPU (cross-platform graphics API)
• Audio: Custom FFT analysis system
• Platform: Windows, macOS, Linux support

🔧 Current Development Status

❌ Recently Claimed (NOT ACTUALLY WORKING)

1. Audio Analysis System: ❌ BROKEN - Code exists but doesn't compile
2. ISF Loader: ❌ BROKEN - 71 shaders exist but cannot be loaded
3. WGPU Renderer: ❌ BROKEN - Rendering code exists but crashes
4. Framework Upgrade: ✅ COMPLETE - Bevy 0.17 + bevy_egui 0.38 (WORKING)
5. Parameter Mapping: ❌ BROKEN - UI code exists but non-functional

🔄 Recovery Plan Required

• Fix 33 compilation errors - Primary blocker
• Rebuild core systems - All features need reconstruction
• Implement actual functionality - Replace stubs with working code
• Add proper error handling - Prevent future crashes

📋 Recovery Roadmap

1. Phase 1: Fix compilation errors (1-2 weeks)
2. Phase 2: Implement basic UI framework (1 week)
3. Phase 3: Add WGPU rendering (1-2 weeks)
4. Phase 4: Implement ISF loading (1 week)
5. Phase 5: Add audio analysis (1 week)

🎮 Usage (CURRENTLY IMPOSSIBLE)

Building (WILL FAIL)

cargo build --release  # ❌ FAILS WITH 33 ERRORS

Running (CURRENTLY BROKEN)

cargo run --release    # ❌ WILL NOT COMPILE

🛡️ Safety Measures

This project implements strict disciplinary measures to prevent destructive actions:

• No Code Deletions: Surgical edits only, no wholesale rewrites
• Framework Consistency: Locked to Bevy 0.17 + bevy_egui 0.38
• Backup Protocol: Regular documentation updates and Git commits
• UI Analyzer: Comprehensive feature detection to prevent regression

📊 Honest Quality Metrics

• Build Success: ❌ 0% (33 compilation errors)
• Core Features: ❌ 0% Complete
• Advanced Features: ❌ 0% Complete
• Documentation: ✅ 100% Complete (but misleading until now)
• Test Coverage: ❌ 0% Complete

🎯 Success Criteria (NOT ACHIEVED)

• ❌ Application opens reliably without panics
• ❌ UI renders consistently with proper layout
• ❌ Basic workflows: load shader, edit, compile, preview
• ❌ Real-time audio analysis with <50ms latency
• ❌ ISF shader loading with full parameter mapping
• ❌ WGPU rendering at 60+ FPS
