Refactored AssetHandlerRegistry to a static class and updated all usages. Replaced the docking-based EngineEditorWindow with a new grid/panel layout, adding modern toolbar, menu bar, and status bar. Introduced new divider styles and improved UI details. Removed obsolete and unused files, updated project references, and made minor code and UI/UX improvements.
Add runtime AssetManager and AssetHandlerRegistrationGenerator source generator.
Update editor asset handler types and services to work with new registration
mechanism and asset catalog. Remove legacy contracts ICloneable and IReleasable.
Files added:
- src/Runtime/Ghost.Engine/AssetManager.cs
- src/Runtime/Ghost.Generator/AssetHandlerRegistrationGenerator.cs
Major edits:
- Editor asset handler classes and services (Asset*, Texture*, Registry)
- Runtime Handle.cs and project files
- Render graph executor and tests updated accordingly
This commit introduces the foundation for the modern asset pipeline
including generated registration of asset handlers and a centralized
runtime AssetManager that will drive asset lifecycle.
Refactored asset management to use a persistent, thread-safe SQLite-backed AssetCatalog, replacing in-memory dictionaries.
Added AssetHandlerRegistry for O(1) handler lookup, ImportCoordinator for async background importing, and robust AssetMeta/AssetMetaIO for JSON-based metadata and settings.
Refactored AssetRegistry to integrate these components and support auto-import via file system watcher.
Updated IImportableAssetHandler for handler-specific settings and polymorphic serialization.
Added comprehensive unit tests for all new systems.
Removed obsolete code and legacy integration tests.
BREAKING CHANGE: Asset system APIs and storage format have changed; migration required for existing projects.
Added a new `code-executor` agent with strict TDD and performance focus. Refactored `TextureProcessor` and `TextureAssetHandler` to use `Magick.NET` for image processing. Enhanced `GPUScene` with `InstanceCounterBuffer` and improved instance management. Introduced a compute shader for GPU scene updates. Updated `GhostRenderPipeline` to handle add/remove instance buffers.
BREAKING CHANGE: Removed `x86` platform support and replaced `CachesFolderPath` with `LibraryFolderPath`. Updated project dependencies and removed unused utility classes.
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.
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.
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 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.
