Implemented meshlet cluster LOD hierarchy with binary-to-4-ary conversion. Updated MeshletHierarchyNode to 4-ary structure. Enhanced SIMD optimizations in GGX mipmap generation. ResourceManager mesh/material creation now supports dynamic buffers and optional naming. Upgraded SPMD package to 1.3.2. Performed minor code cleanups and doc improvements.
Major overhaul of material palette management:
- Added two-buffer indirection (PaletteOffsetBuffer, MaterialIndexBuffer) for GPU material lookup, with incremental upload and resizing.
- MaterialPaletteStore now tracks dirty ranges, supports deferred slot reclamation, and exposes CPU-side arrays for upload.
- ResourceManager manages persistent GPU buffers and uploads only dirty subranges per frame.
- Updated HLSL and C# structs to use palette indices.
- Refactored systems/components to use new palette index and release logic.
- Added RenderContext.UploadBufferRange for partial uploads.
Minor: Fixed StbIApi interop signatures, updated test namespaces, and performed code cleanups.
Major refactor of graphics pipeline keying, shader cache, and resource allocation.
Replaced most Allocator usage with AllocationHandle, modernized logger usage,
and unified pipeline state keys. Updated MeshUtility to use AllocationHandle.FreeList.
Added new shader pipeline architecture docs and improved error handling throughout.
BREAKING CHANGE: Pipeline keying and resource allocation APIs have changed.
Refactored the shader compilation pipeline to introduce modularity, improve performance, and enhance maintainability. Key changes include:
- Added `ShaderCompilationConfig`, `CompilerOptimizeLevel`, and `ShaderStage` enums.
- Replaced `SM` property with `ShaderModel` in shader models.
- Introduced `ShaderLibrary` for in-memory and disk-based shader caching.
- Refactored `DSLShaderCompiler` and `AntlrShaderCompiler` for better hashing and error handling.
- Centralized shader compilation logic in `ShaderCompilerUtility`.
- Removed legacy shader compilation logic from `IShaderCompiler`.
- Updated `RenderGraph`, `ResourceManager`, and `Material` to integrate with the new caching system.
- Improved memory management with `NativeMemoryManager<T>`.
BREAKING CHANGE: Removed legacy shader compilation methods and replaced them with a new caching and compilation system.
Refactored shader compilation and resource management systems:
- Introduced `DXCShaderCompiler` for HLSL compilation and reflection.
- Added `BuildFinalShaderCode` method for robust shader code generation.
- Replaced raw strings with `ShaderEntryPoint` struct for shader paths.
- Updated `RenderContext` and `RenderGraphContext` for new pipeline methods.
- Added thread-safe resource management methods in `ResourceManager`.
- Introduced `DXCShaderReflectionData` for shader reflection handling.
- Removed redundant code and simplified `ShaderPropertiesRegistry`.
BREAKING CHANGE: Updated shader and resource APIs to use new structures and methods.
