- Create unified RHIResourceView base interface with type-specific Initialize methods
- Implement D3D12ResourceView with RTV/DSV/SRV/UAV/CBV support
- Implement OpenGL ResourceView simulation layer using FBO, texture units, and UBO
- Add OpenGLTextureUnitAllocator for managing texture unit bindings
- Add OpenGLUniformBufferManager for UBO binding points
- Add OpenGLFramebuffer for FBO management
- Remove deprecated D3D12 view classes (RenderTargetView, DepthStencilView, etc.)
- Fix ExecuteCommandLists type confusion bug by adding GetNativeHandle to RHICommandList
- Fix test bug where Close() was called before ExecuteCommandLists
- Update all integration tests to use new D3D12ResourceView class
- All tests pass: 144 unit tests + 8 integration tests
- Remove IsSignaled() from RHIFence interface (semantic inconsistency)
- Remove Reset() from OpenGL implementation (no D3D12 counterpart)
- OpenGL Fence now uses single GLsync + CPU counters for timeline simulation
- OpenGL Fence Initialize() now accepts uint64_t initialValue (was bool)
- Add comprehensive timeline semantics tests for all backends:
- Signal increment/decrement scenarios
- Multiple signals
- Wait smaller than completed value
- GetCompletedValue stages verification
- Update documentation to reflect actual implementation
- Add m_boundRenderTargets and m_boundDepthStencil members to D3D12CommandList
- SetRenderTargetsHandle now saves bound RTV handles for later clear operations
- ClearRenderTargetView(ID3D12Resource*, ...) clears all bound render targets
- Reset() clears bound targets list
- Follows D3D12 best practice: RTV is bound via OMSetRenderTargets, then cleared
- CommandQueue::ExecuteCommandLists: fix type conversion from void** to ID3D12CommandList**, reset command list before execution, add null checks
- SwapChain::ShouldClose: add m_shouldClose member and implement getter/setter
- SwapChain::SetFullscreen: add m_fullscreen member to track state locally
- Add default value handling for sampleCount, mipLevels, depth in CreateTexture
- Add RTV descriptor heap to D3D12CommandList for future ClearRenderTarget implementation
- ClearRenderTarget remains stub (requires full D3D12 render pipeline state)
- Rename D3D12Enum.h to D3D12Enums.h for naming consistency
- Fix OpenGL unit test GLAD initialization by using gladLoadGL()
instead of gladLoadGLLoader(wglGetProcAddress) for fallback support
- Migrate remaining tests to use gtest_discover_tests for granular
test discovery (math, core, containers, memory, threading, debug,
components, scene, resources, input, opengl)
- Remove obsolete TEST_RESOURCES_DIR and copy_directory commands
from OpenGL unit test CMakeLists (minimal/Res doesn't exist)
- Update TEST_SPEC.md with performance metrics and per-module
build/test commands for faster development workflow
- Update CMake path references to use lowercase paths
- Fix TranslationMatrix to use correct indices (m12/m13/m14 for translation)
- Fix PerspectiveMatrix projection formula
- Enable depth testing (was disabled)
- Add texture sampling in pixel shader
- Adjust sphere radius to 1.0 and position to z=5
- Fix D3D12Buffer copy size calculation
- Add assert() bounds check to GetBackBuffer() to catch invalid indices
- Include <cassert> in D3D12SwapChain.cpp
- Update test_swap_chain.cpp to use reference return type
- Mark InvalidIndex test as DISABLED (assert aborts on invalid index)
- Update get-back-buffer.md documentation
- Add D3D12Screenshot::Capture(D3D12Device&, D3D12CommandQueue&, D3D12Texture&, const char*) wrapper overload
- Update minimal integration test to use encapsulated APIs
- Add DescriptorHeap wrapper unit tests
- Document minimal GetBuffer native call as known limitation in TEST_SPEC.md
- Add DepthStencilState and BlendState structs to RHICommandList
- Add SetPrimitiveTopology, SetDepthStencilState, SetStencilRef,
SetBlendState, SetBlendFactor virtual methods
- Implement new methods in OpenGL backend with full state control
- Implement stub methods in D3D12 backend (states controlled via PSO)
- D3D12Device no longer inherits from IRHIDevice interface
- Removed interface factory methods (CreateCommandQueue, CreateCommandList, etc.)
- Keep concrete D3D12-specific methods (Initialize, Shutdown, GetDevice, etc.)
- This is the first step to decouple RHI abstraction from D3D12 backend
