HLSL++ math, Graphics API optimizations, automated static code analysis, unit-tests code coverage, code improvements and extensive refactoring were done in this release:

  • Samples and tutorials:
    • Migrated tutorials and samples from CML to HLSL++ vector math library with SIMD intrinsics acceleration for CPU. Removed explicit alignment of uniform structure fields, which is not required anymore for HLSL++ types, since they already use 16-bytes aligned data storage.
    • Asteroids sample was optimized with up to 50% FPS increase:
      • Uniforms buffer size was reduced by reusing scene view-projection matrix in shaders (+7% FPS)
      • Uniforms buffer data transfer is made asynchronously with draw commands encoding (+20% FPS)
      • Disabled repeated retaining of the bound resources in command list draw calls (+30% FPS)
      • Disabled automatic resource barriers setup during parallel asteroids rendering to take advantage of automatic state propagation from Common state.
      • Got rid of excessive program binding calls in DirectX as a result of using Frame-Constant argument accessors in program bindings.
  • Documentation updates:
  • Common libraries:
    • Primitives library extended with error handling (closed #74):
      • Methane/Exceptions.hpp was added with common exception type defintions
      • Methane/Checks.hpp was added with error checking macro definitions aka META_CHECK*
      • META_LOG macros has been updated to make string formatting using FMT library inside of the macro using variadic arguments
  • Data libraries
    • RawVector template class was added as a replacement of cml::vector for dense-packed components storage used in vertex attributes.
    • Point template class now use underlying HLSL++ vector and unifies 2D and 3D implementations.
    • Rect and RectSize, Volume and VolumeSize classes were refactored. Made class fields private, available through accessors.
    • Constants template class was added with math constants.
  • Platform libraries
    • Platform App library was updated with unified error handling logic in AppBase class, moved from platform specific classes
  • Graphics libraries
    • Graphics Core changes:
      • Program binding improvements:
        • Program::Argument and Program::ArgumentAccessor (previously Program::ArgumentDesc) were refactored from struct to class style with field accesor functions. Program::Argument::Modifiers bit-mask was replaced with Program::ArgumentAccessor::Type enum.
        • New program argument accessor type was added for frame-constant arguments Program::ArgumentAccessor::Type::FrameConstant to reduce number of excessive argument binding setup calls. Frame-constant bindings are properly supported by DX descriptor table layout.
        • Frame-buffer index was added to ProgramBindings::Create function as an optional argument to support frame-constant bindings.
        • Applying of DirectX resource states and root parameter bindings was reworked in ProgramBindingsDX.
      • Resource upload and state synchronization improvements:
        • COPY comamnd queue is now used by default for BlitCommandList execution in DirectX (instead of DIRECT command queue used before). So the resources upload is also done with a COPY queue in DX now. It can be switched back to using DIRECT queue with RenderContext::Settings::options_mask bit-mask flag Context::Options::BlitWithDirectQueueOnWindows.
        • Resource::SetData method is extended with an optional argument of command queue for resource state synchronization. Command queue where resource is actually used should be passed whenever possible.
        • Resource barriers setup was moved from the Resource::SetData method implementations to the SetProgramBindings, SetVertexBuffer and SetIndexBuffer calls, while setup resource barriers are still cached inside Resource object.
        • Resource::State and Resource::Barriers types were moved to the public header files and split from Resource interface definition.
      • CommandKit interface was added to Graphics Core to provide unified access from Context::GetDefaultCommandKit to the command queue, command lists, command list set and synchronization fences made for working together with the same CommandList::Type. This interface allowed to replace methods Context::GetUploadCommandQueue, Context::GetUploadCommandList, Context::GetUploadCommandListSet and RenderContext::GetRenderCommandQueue with Context::GetDefaultCommandKit.
      • CommandList changes:
        • CommandList::SetResourceBarriers(...) call was added to the public interface (was private before).
      • RenderCommandList changes:
        • RenderCommandList::ResetWithStateOnce method was added additionally to ResetWithState to skip command list reset when it is already in Encoding state with the same RenderState already applied.
        • RenderCommandList::SetIndexBuffers method was adedd, index buffer is now set separately from DrawIndexed call.
        • RenderCommandList::Set[Index|Vertex]Buffers methods were exnteded with an optional argument which allows to disable setting resource barriers automatically.
      • ParallelRenderCommandList changes:
        • Child render command lists are now committed in parallel.
      • ImageLoader now initializes texture names inside Load functions.
      • Changed ResourceBase derived classes hierarchy based on template implementation of Resource[DX|MT|VK]<ResourceBaseType> which is replacing ResourceNT alias class
      • Removed almost all Native platform alias headers
      • Fixed some memory leaks in Metal implementation on MacOS
      • Fixed const correctness for Device and Context references passed to core interface factory functions
    • Graphics::App template class implementation was split to Graphics::AppBase to reduce template code and speedup compilation
    • Color template class was rewritten from scratch and now can use both integer and floating point components via underlying HLSL++ vector storage
    • ArcBallCamera unit-tests were improved and uncovered some issues in tested class implementation. Issues were fixed
    • SphereMesh generation was simplified with matrix-free implementation
    • Fixed missing debug names of graphics resources (regression of previous refactoring)
    • Fixed mip-levels count in depth texture descriptor for DirectX12

    • Enabled naming of Tracy GPU contexts
  • User Interface libraries
    • Unified UnitType derived classes implementation within one template class
    • Fixed bug in Text mesh generation with multiple zero characters at the end of the string
    • Text rendering is now calling ResetWithStateOnce instead of ResetWithState to minimize rendering state resets in sequence of several text blocks
  • Unit-tests coverage was expanded from 5.7% to 13%:
    • RawVector, Point new template classes were covered with unit-tests.
    • Rect and RectSize, Volume and VolumeSize existing template classes were covered with unit-tests.

  • Global code changes:
    • Replaced CML math library with HLSL++ to improve math performance with SIMD instructions (close #78).
    • Debug logging was extended for resource barriers synchronization, render and view state parameters and cleaned up: properly used magic_enum, removed manual enum to string conversion functions, fixed logs formatting.
    • Properly implemented or enabled default generation of assignment operators, copy and move constructors for all applicable types
    • Used MagicEnum library extensively to remove enum code bloat and improve type safety with enum class types:
      • Uses enum class types for bit-masks instead of raw enum types to improve type safety.
      • Generating string names of enum values with a single line of code
      • Iterating over enum values and getting values count
    • All modules updated with fixes of static code analysis issues from SonarCloud (closed #73):

      • Throw undefined enum value exception in default branches of all switch blocks to fix repeated analysis issue
      • Replaced std::function usage with template arguments wherever possible to improve performance
      • Used fmt::format(...) for string formatting wherever possible project wide
      • Used magic_enum library to replace raw enum types of bit-masks to enum class types, use enum names and counts generated in compile time.
