flutter_gaussian_splatter 0.3.0

Flutter Gaussian Splatter

0.3.0 - 2025-09-08

🏗️ Architecture Overhaul

• BREAKING: Complete restructure from monolithic to service-based architecture
• feat: new modular service-based renderer architecture with separated concerns
• feat: file restructuring - moved from core/ to domain-specific directories
• feat: shader factory system for better shader management
• feat: render pass abstraction for extensible rendering pipeline

🚀 Performance & Rendering Improvements

• feat: instanced rendering with batched draw calls (128 splats per instance)
• feat: alpha write control for bandwidth optimization
• feat: maximum splat size limiting to prevent excessive overdraw
• feat: improved Mali GPU compatibility and Android rendering stability
• fix: coordinate system consistency across platforms (Android vs iOS)
• fix: vsync synchronization with Flutter's frame scheduling

🔧 Technical Enhancements

• feat: consolidated camera perspective logic with immutable camera model
• feat: background sky dome refactored as proper render pass
• fix: improved texture format fallback (R32UI → RGBA32F)
• fix: vertex shader optimizations with conditional compilation
• fix: Android floating-point texture compatibility
• chore: comprehensive linting and code cleanup
• docs: added detailed renderer architecture documentation
