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 pStrides  parameter from IDeviceContext::SetVertexBuffers(). Strides are now defined through vertex layout.
• API Changes:
  • 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
  • Added NumViewports  member to GraphicsPipelineDesc structure
• Samples:
  • Added fullscreen mode selection dialog box
  • Implemented fullscreen mode toggle on UWP with shift + enter
  • Implemented fullscreen window toggle on Win32 with alt + enter
  • Added Tutorial 09 – Quads

v2.2.a

• Enabled Win32 build targeting Windows 8.1 SDK
• Enabled build customization through custom build config file
• Implemented PSO compatibility
• Fixed the following issues:
  • Messy #include structure?
  • Move GetEngineFactoryXXXType and LoadGraphicsEngineXXX to Diligent namespace
  • Customizable build scripts
  • Win32FileSystem related functions should use wchar_t (UTF-16)

v2.2

Added MacOS and iOS support

v2.1.b

• Removed legacy Visual Studio solution and project files
• Added API reference
• Added tutorials 1-8

v2.1.a

• Refactored build system to use CMake and Gradle for Android
• Added support for Linux platform

v2.1

• Core
  • Interoperability with native API
  • Accessing internal objects and handles
  • Createing diligent engine buffers/textures from native resources
  • Attaching to existing D3D11/D3D12 device or GL context
  • Resource state and command queue synchronization for D3D12
• Integraion with Unity
• Geometry shader support
• Tessellation support
• Performance optimizations
• HLSL->GLSL converter
  • Support for structured buffers
  • HLSL->GLSL conversion is now a two-stage process:
    • Creating conversion stream
    • Creating GLSL source from the stream
  • Geometry shader support
  • Tessellation control and tessellation evaluation shader support
  • Support for non-void shader functions
  • Allowing structs as input parameters for shader functions

v2.0 (alpha)

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

• Pipeline State Object encompasses all coarse-grain state objects like Depth-Stencil State, Blend State, Rasterizer State, shader states etc.
• 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
