Introduces a new Ghost.Shader.Concept project implementing a modern, data-oriented material and shader system with:
- Global/local keyword bitsets (fast O(1) ops, 64 bytes)
- Multi-pass shader program and per-pass render state overrides
- Thread-safe, 16-byte aligned material property blocks
- Material pooling to reduce GC pressure
- Batch renderer for efficient PSO grouping and async variant warmup
- Full demo (Program.cs) and extensive documentation (ARCHITECTURE.md, README.md, PROJECT_SUMMARY.md)
- Minor integration: new enums, doc updates, and keyword handling in existing code
No breaking changes to the existing engine; all new code is isolated. This serves as a reference implementation for high-performance, extensible material/shader architectures.
Updated multiple components to improve encapsulation, maintainability, and performance. Key changes include:
- Upgraded package dependencies in project files.
- Refactored `Mesh` and `RenderingContext` to use properties and added support for per-object constant buffers.
- Improved resource management in `D3D12CommandBuffer`, `D3D12CommandQueue`, and `D3D12ResourceAllocator` with better encapsulation and disposal handling.
- Added validation for constant buffer sizes in `D3D12PipelineLibrary`.
- Simplified `MeshBuilder` methods to accept allocators and removed hardcoded values.
- Enhanced debugging with `GPUResourceLeakException` and resource tracking updates.
- Updated shaders and rendering logic for testing, including hardcoded triangle rendering.
- Removed redundant base classes and interfaces for cleaner code structure.
