Release v.2.3.b is out with Vulkan support on Linux and other improvements

Release v2.3.b notes:

• Enabled Vulkan backend on Linux
• API Changes
  • Implemented separate texture samplers:
    • Added

      UseCombinedTextureSamplers

        and

      CombinedSamplerSuffix

        members to

      ShaderCreationAttribs

       structure.
      When separate samplers are used (

      UseCombinedTextureSamplers == false

      ), samplers are set in the same way as other shader variables via shader or SRB objects.
    • Removed

      BIND_SHADER_RESOURCES_RESET_BINDINGS

       flag, renamed

      BIND_SHADER_RESOURCES_KEEP_EXISTING

       to

      BIND_SHADER_RESOURCES_KEEP_EXISTING

      .
    • Added

      BIND_SHADER_RESOURCES_UPDATE_STATIC

      ,

      BIND_SHADER_RESOURCES_UPDATE_MUTABLE

      ,

      BIND_SHADER_RESOURCES_UPDATE_DYNAMIC

      , and 

      BIND_SHADER_RESOURCES_UPDATE_ALL

        flags
• Using glslang to compile HLSL to SPIRV in Vulkan backend instead of relying on HLSL->GLSL converter
• Bug fixes

Previous release history

v2.3.a

• Core
  • Added

    IFence

      interface and

    IDeviceContext::SignalFence()

      method to enable CPU-GPU synchronization
  • Added

    BUFFER_MODE_RAW

      mode allowing raw buffer views in D3D11/D3D12.
  • Moved Format member from

    BufferDesc

      to

    BufferViewDesc

  • Removed

    IsIndirect

      member from

    DrawAttrbis

      as setting

    pIndirectDrawAttribs

      to a non-null buffer already indicates indirect rendering
• Samples:
  • Added Tutorial 10 – Data Streaming
  • Added Tutorial 11 – Resource Updates

v2.3

• Core:
  • Implemented Vulkan backend
  • Implemented hardware adapter & display mode enumeration in D3D11 and D3D12 modes
  • Implemented initialization in fullscreen mode as well as toggling between fullscreen and windowed modes in run time
  • Added sync interval parameter to

    ISwapChain::Present()

  • API Changes
    • Added

      NumViewports

        member to

      GraphicsPipelineDesc

       struct
    • Removed

      PRIMITIVE_TOPOLOGY_TYPE

       type
    • Replaced

      PRIMITIVE_TOPOLOGY_TYPE GraphicsPipelineDesc::PrimitiveTopologyType

        with

      PRIMITIVE_TOPOLOGY GraphicsPipelineDesc::PrimitiveTopology

      
      Removed

      DrawAttribs::Topology

      
      Removed

  • Math library functions

    SetNearFarClipPlanes()

     ,

    GetNearFarPlaneFromProjMatrix()

     ,

    Projection()

     ,

    OrthoOffCenter()

     , and

    Ortho()

      take

    bIsGL

      flag instead of

    bIsDirectX

  • Vertex buffer strides are now defined by the pipeline state as part of the input layout description (

    LayoutElement::Stride

    )
  • Added

    COMMIT_SHADER_RESOURCES_FLAG_VERIFY_STATES

      flag

v2.0 (alpha)

Alpha release of Diligent Engine 2.0. The engine has been updated to take advantages of Direct3D12:

• New shader resource binding model implemented to leverage Direct3D12
• OpenGL and Direct3D11 backends
• Alpha release is only available on Windows platform
• Direct3D11 backend is very thoroughly optimized and has very low overhead compared to native D3D11 implementation
• Direct3D12 implementation is preliminary and not yet optimized

v1.0.0

Initial release
