- Add RHITestFixture with RHI_BACKEND env var support for backend selection
- Add unit tests for: Device, Buffer, Texture, SwapChain, CommandList, CommandQueue, Shader, Fence, Sampler
- Tests can run against D3D12 or OpenGL backends via RHI_BACKEND env var
- Add integration folder placeholder for future integration tests
- Add VertexAttributeType and VertexAttributeNormalized enums in OpenGLVertexArray.h
- Add ToGLAttributeType() converter in OpenGLVertexArray.cpp
- Remove glActiveTexture() call from quad test (already handled by texture.Bind())
- Remove #include <glad/glad.h> from triangle test
- Update unit tests to use encapsulated enums
All three OpenGL integration tests (minimal, triangle, quad) pass with 0% pixel difference.
The band index was incorrectly calculated using pointer arithmetic on a
local parameter address, which is meaningless. Now uses the band index
passed as a parameter instead.
- Add Component class documentation with lifecycle methods
- Add GameObject class documentation with component system
- Add TransformComponent documentation with transform methods
- Add Scene class documentation with GameObject management
- Add SceneManager singleton documentation with scene loading
- Update components.md overview with all component classes
- Update main.md navigation with Scene module
- Implement ParseWAVData and ParseWAVHeader in AudioLoader to properly
parse WAV file headers (sample rate, channels, bits per sample, duration)
- Modify Load() to call ParseWAVData for WAV files during loading
- Add DecodeAudioData() to AudioSourceComponent to decode PCM bytes to float
- Update SetClip() to trigger audio decoding
- Fix ProcessAudio() to read from decoded data instead of empty output buffer
- Add WAV parsing unit tests (ParseWAV_Mono44100_16bit, ParseWAV_Stereo48000_16bit)
Fixes issues:
- AudioLoader::ParseWAVData was a stub returning true without parsing
- AudioLoader::Load didn't extract audio metadata from WAV headers
- AudioSourceComponent::ProcessAudio read from empty m_outputBuffer
All 167 tests pass.
- Replace glViewport() with commandList.SetViewport()
- Replace glClearColor()+glClear() with commandList.Clear()
- Add OpenGLCommandList include and instance
- Create TEST_SPEC.md with OpenGL test hierarchy and specifications
- Add section and inline comments to main.cpp explaining:
- Window size calculation with AdjustWindowRect
- glFinish before screenshot for GPU sync
- Target frame count warm-up period
- Shutdown order (reverse of initialization)
- OpenGLSwapChain::Initialize now uses AdjustWindowRect before SetWindowPos
- This ensures window client area matches expected size (1280x720)
- Previously SetWindowPos was given client area size instead of full window size
- Removed debug fprintf statements from OpenGLDevice
- Updated minimal integration test to use cleaner code
- Simplify OpenGL integration test structure
- Enable CTest registration for OpenGL tests
- Refactor test fixtures and device enumeration
- Minor code cleanup and improvements
- Add triangle test with vertex buffer and custom pipeline state
- Add triangle.hlsl shader with position and color per vertex
- Fix cull mode (NONE) and disable depth test for correct rendering
- Register D3D12_Triangle_Integration CTest
- Add GT.ppm golden image
- 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 OpenGL_Minimal integration test using Win32 native API + glad
- Copy run_integration_test.py and compare_ppm.py from D3D12
- Create minimal/main.cpp with red clear color (matching D3D12)
- Generate GT.ppm golden template for 1280x720 red window
- Add VertexArray_Bind_MultipleAttributes unit test
- Update integration/CMakeLists.txt to build OpenGL_Minimal target
