Summary

Methane Kit v0.8.1 update modernizes the project with a switch to the C++20 standard, introducing features like designated initializers, concepts, span, ranges and simplified implementation of comparison operators. Comprehensive unit tests were added for all "Graphics RHI" classes, increasing code coverage of the core modules. Build with Visual Studio 2019 is no longer supported, CMake build configurations were removed for VS2019.

Common changes

• Upgraded project code and switch to the C++20 standard (close #141 ):
  • Use designated initializers for RHI settings;
  • Use concepts instead of SFINAE in templates;
  • Use std::span in RHI interfaces extensively, instead of references to std::vector;
  • Get rid of stdext::checked_array_iterator in favor of std::span;
  • Reduce enums verbosity across all code with help of using enum;
  • Use std::numbers instead of Methane::Data::Constants;
  • Use default implementations of the three-way comparison or equality operators wherever possible and remove manually defined comparison operators, which can be auto-generated now;
  • Use range-based algorithms.
• Used hidden friend pattern for binary operators.
• Increased minimum CMake version up to 3.24.

Graphics libraries

• Added ObjectRegistry PIMPL wrapper to simplify registry use.
• Fixed multithreaded access violation in Base::RenderPass.
• Removed excessive parameter id from IResourceBarriers::Add method.
• Added GetRenderPass() method to class ParallelRenderCommandList.
• Added GetComputeCommandKit() method to class RenderContext.
• Refactored method ITexture::GetTextureView to return TextureView instead of ResourceView.

Data libraries

• Used lambdas instead std::function in Animation classes

Tests

• Added unit-tests to cover all classes of the "Graphics RHI" layer (close #122):
  • System tests were added.
  • Device tests were added.
  • RenderContext tests were added.
  • RenderState tests were added.
  • RenderPattern tests were added.
  • RenderPass tests were added.
  • RenderCommandList tests were added.
  • ParallelRenderCommandList tests were added.
  • CommandListSet tests were added.
  • ResourceBarriers tests were added.
• Added unit-tests for all template classes of the "Graphics Mesh" library.
