Modernizes resource and barrier management for the D3D12 backend. Key changes:
- Simplifies BarrierDesc by removing nullable "before" states; now inferred from resource database.
- Adds IsAliasing flag to BarrierDesc for aliasing transitions.
- Replaces ResourceMemoryType with HeapType in BufferDesc and related APIs.
- Enhances ResourceViewGroup with usage inference methods.
- Adds D3D12 utility helpers for heap/flag conversions and resource description extraction.
- Optimizes command buffer barrier emission, skipping redundant barriers.
- Refactors Material and RenderContext to use new APIs and state tracking.
- Updates ResourceManager pooling to use HeapType and standard Queue.
- Simplifies RenderGraphExecutor barrier logic and aliasing handling.
- Improves RenderSystem frame synchronization and resource retirement.
- Cleans up obsolete code and improves debug output.
BREAKING CHANGE: Updates to resource and barrier APIs require changes to all code interfacing with resource creation, barriers, and memory types.
Major overhaul of GPU resource/heap management:
- Replace resource pooling and upload buffer logic with transient heap/page-based suballocation in ResourceManager.
- Add support for suballocation and heap flags/types, with D3D12 helpers.
- Remove ICommandBuffer.UploadBuffer/UploadTexture; add UpdateSubResources and CopyBuffer, move upload logic to RenderingContext.
- Refactor D3D12ResourceAllocator/Database for suballocation, heap flags, and mapping.
- Standardize on Handle<GPUBuffer> usage.
- Update meshlet/mesh utilities for new allocation handles and memory pools.
- Refactor RenderGraph and docs to use "heap" terminology.
- Use cpuFrame/gpuFrame consistently for frame sync.
- Add s2h.hlsl, s2h_3d.hlsl, s2h_scatter.hlsl shader debug libs.
- Miscellaneous fixes, cleanup, and dependency updates.
BREAKING CHANGE: Resource pooling and upload APIs replaced with new heap/page-based suballocation system. Update all buffer/texture creation and upload code to use new ResourceManager and ICommandBuffer methods.
Refactor meshlet build pipeline for robustness and performance.
Rename DxcShaderCompiler to DXCShaderCompiler. Enhance meshlet
data structures with bounds and LOD info. Add fallback mesh
simplification. Remove obsolete MeshRenderPass. Add
MeshoptBenchmark for meshlet build performance. Update mesh
import utilities for correct handedness. Minor bug fixes and
code cleanups.
Added NoAccess to attachment ops for depth/stencil, updated D3D12 and RenderGraph to handle new ops, and improved axis/handedness conversion in mesh loading. Enabled meshlet color hashing in test shader. Changed default rasterizer winding, added format helpers, and updated camera transform for correct mesh orientation. JobScheduler usage commented out for now.
Add logic to skip generic SRV barriers for resources explicitly handled as color, depth, or random access in raster passes, preventing redundant transitions. Update RGTextureDesc to accept a TextureUsage parameter for more flexible texture descriptor creation.
Refactored native wrappers to use ReadOnlySpan<T> for pointer parameters, improving .NET safety and interop. Enhanced wrapper generator with $TYPE and prefix/suffix-based parameter remapping. Added platform-specific native library loading for meshoptimizer, nvtt, and ufbx. Updated D3D12GraphicsEngineFactory for native DLL resolution and removed redundant logic from UnitTestApp. Changed RenderGraphBuilder's resource extraction API to use QueryTextureExtraction/QueryBufferExtraction with explicit handles and flags. Removed IRenderer and D3D12Renderer, moving RenderContext to RenderPipeline. Improved mesh loading, resource management, and updated test shader conventions. Updated project references, build settings, and added launchSettings.json for tooling.
BREAKING CHANGE: Native wrapper APIs now use ReadOnlySpan<T> instead of pointers. RenderGraphBuilder resource extraction API has changed. IRenderer and D3D12Renderer have been removed.
Refactored Vertex to use float3 position/normal, float2 uv, float4 tangent, and Color128 color, updating all mesh generation and HLSL code accordingly. Added MeshUtility for loading .obj/.fbx meshes with deduplication and normal/tangent computation. Updated GraphicsTestWindow to use the new loader and improved resource management. Fixed D3D12ResourceAllocator resource creation logic, improved camera projection math, and simplified RenderingLayerMask. Updated package references and app display name.
BREAKING CHANGE: Vertex struct layout changed; all mesh code and shaders must use the new format.
Refactored all graphics resource handles to use Handle<GPUTexture> and Handle<GPUBuffer> instead of Handle<Texture> and Handle<GraphicsBuffer>. Updated all APIs, interfaces, and implementations to use the new types, including ICommandBuffer, IResourceAllocator, ISwapChain, IRenderOutput, IRenderGraphBuilder, and related classes. Introduced TempJobAllocator for frame-latency-aware allocations. Updated ResourceHandleExtensions for new conversions. Performed minor code cleanups and removed the empty ClusterLod.cs file.
BREAKING CHANGE: All usages of Handle<Texture> and Handle<GraphicsBuffer> are replaced with Handle<GPUTexture> and Handle<GPUBuffer>. This affects all APIs and resource management code. Callers must update their code to use the new handle types.
Refactored ProjectBrowser to use GridView instead of ItemsView for file display, updated selection logic, and set a minimum grid height. FloatingWindow now manages DockingLayout cleanup on close to prevent resource leaks. Simplified DockDocument and DockGroup instantiations in EngineEditorWindow. Updated GetDirectoryNameConverter to use Path.GetDirectoryName directly. App shutdown now calls EditorApplication.Shutdown(). Added Ghost.Engine reference in ActivationHandler.
- Add DockLength property to DockModule to track star weights
- Add SyncLengths() to DockPanel to capture current Grid weights
- Update DockPanel.UpdateLayoutStructure to use DockLength
- Update DockingLayout.SplitGroup to distribute weights when splitting
Refactored DockGroup to only remove obsolete TabViewItems and restore tab selection more reliably. Updated DockGroup.xaml to enable tab reordering and add-tab button. Switched to CommunityToolkit.WinUI.Controls for GridSplitter and added a style for it. Made DockPanel, DockRegionHighlight, and DockingLayout partial classes. In App.xaml.cs, wrapped initialization in a try-catch to exit on error, and ensured process exit on window close. Improved ProjectBrowser scrollbar behavior and layout settings.
- Throw ArgumentException in DockContainer.ReplaceChild if newChild is already in the container to avoid index shifting bugs.
- Add comment in DockPanel.CheckCleanup explaining the asymmetric root panel collapse behavior.
