- Use Matrix4x4 type directly instead of float[16]
- Remove wrapper functions (IdentityMatrix, TranslationMatrix, PerspectiveMatrix, LookAtMatrix, MultiplyMatrix, TransposeMatrix)
- Direct use of Matrix4x4::Identity(), Matrix4x4::Translation(), Matrix4x4::Perspective()
- Transpose matrices before uploading to GPU to match HLSL column-major
- Update Math module Perspective and Orthographic to left-handed coordinate system
- Update math unit tests for new matrix values
- Enable depth write mask (D3D12_DEPTH_WRITE_MASK_ALL) to fix rendering artifacts
- Change texture address mode from Wrap to Clamp to fix UV seam tearing
- Remove V coordinate flip in shader to fix upside-down texture
- Add ground truth screenshot (GT.ppm) for testing
- 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
