Major overhaul of Render Graph system:
- Replaced texture handles with generic Identifier<T> for unified, type-safe resource management (textures, buffers, etc.)
- Refactored resource registry and pooling for performance and extensibility
- Added AccessFlags and TextureAccess for precise resource usage tracking
- Split passes into Raster and Compute types; introduced builder interfaces for safer pass construction
- Modernized pass setup API (SetColorAttachment, UseTexture, etc.)
- Updated command buffer and context structs to use new resource system
- Refactored barrier and aliasing logic for improved correctness
- Integrated BenchmarkDotNet for performance/memory benchmarking
- Improved blackboard type safety and removed obsolete code/extensions
- Added BenchmarkDotNet NuGet package
These changes make the Render Graph more extensible, efficient, and ready for future resource types and advanced features.
- Major architectural refactor for performance, extensibility, and feature completeness: resource pooling, pass culling, aliasing, and compilation caching.
- Introduces type-safe builder and context APIs, blackboard pattern, and unified resource management.
- Adds detailed documentation and cleans up obsolete files and APIs.
- Includes (commented) Unity Render Graph source for reference; not compiled, for parity and future extension.
- Major optimization of Ghost.RenderGraph.Concept: pooled resources, zero-allocation hot paths, explicit queue types, and batch barrier APIs.
- Migrated Ghost.DSL shader compiler to ANTLR4-based parser; removed hand-written parser, added grammar files and semantic model conversion.
- Added CollectionPool/ListPool for pooled list management.
- Updated documentation for new architecture and performance.
- Removed Ghost.Shader.Concept (material/material system) from repo and solution.
- README.md replaced with a brief project statement.
Implemented a transient render graph system as a proof of concept, including resource aliasing, pass culling, and typed pass data. Added new project `Ghost.RenderGraph.Concept` targeting `.NET 10.0`.
Refactored graphics-related components:
- Simplified resource state transitions in `RenderingContext`.
- Improved resize handling in `GraphicsTestWindow`.
- Updated `D3D12GraphicsEngine` to streamline frame rendering.
- Enhanced `D3D12ResourceDatabase` and `D3D12SwapChain` for better resource management.
Added detailed documentation:
- `ALIASING.md` explains resource aliasing techniques.
- `API_DESIGN.md` outlines the render graph API design.
Updated solution to include the new render graph project.
