Major refactor of shader compiler and related systems:
- Switch ShaderDescriptor/PassDescriptor to arrays; remove IPassDescriptor
- Rewrite keywords block parser/semantic analysis for flexible syntax
- Change property initializers to brace syntax `{ ... }`
- Simplify TokenStream API (remove ref index params)
- Make GetBindlessIndex return uint (~0u for not found)
- Update shader compilation and variant logic for new descriptors
- Update test shader syntax to match new property/keyword formats
- Add AGENTS.md agent development guide
- Add Antlr4 dependency to Ghost.DSL
- Miscellaneous code style and error handling improvements
Major architectural update to graphics/material/shader system:
- Introduced strongly-typed key structs (Key64/Key128) for passes, variants, and pipelines; removed legacy key types.
- Implemented robust hashing and key generation utilities for efficient variant and pipeline lookup/caching.
- Shader compiler now compiles/caches all keyword variants using new key system; includes handled as lists.
- Switched to push constant root signature for per-draw data; updated HLSL and C# codegen accordingly.
- Refactored Material, Shader, and Pass data structures for cache efficiency and variant support.
- Pipeline library and PSO management now use 128-bit keys and variant-specific caching.
- Replaced WorldNode with SceneNode in editor/scene graph; introduced ComponentManager for archetype/query management.
- Migrated math utilities to Misaki.HighPerformance.Mathematics; updated editor controls.
- Updated all HLSL and codegen for new buffer/push constant layouts and macros.
- Misc: project reference cleanup, D3D12 Work Graph support, doc updates, and code modernization.
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.
- Updated dependencies, including `Misaki.HighPerformance` and `TerraFX.Interop`.
- Refactored `Result` struct for better error handling and chaining.
- Removed `Ptr<T>` struct as it was no longer necessary.
- Enhanced `Win32Utility` with `Attach` and `Dispose` methods.
- Improved `ProjectService` and `AppStateMachine` with `Result` integration.
- Refactored `IShaderCompiler` to support SPIR-V cross-compilation and pass-level compilation.
- Standardized Direct3D12 resource management with `UniquePtr` and added `D3D12Object` base class.
- Improved shader reflection validation and pipeline creation in `D3D12PipelineLibrary`.
- Updated `SDLCompiler` for better error handling during shader generation.
- Enhanced logging, debugging, and code readability across the codebase.
- Performed general code cleanup, including unused namespace removal and naming consistency.
