  • Implemented Vulkan backend
  • Implemented PSO compatibility: if two pipeline states share the same shader resource layout, they can use SRB objects interchangeably.
  • Added IPipelineState::IsCompatibleWith(const IPipelineState *pPSO) method that returns true if two pipeline states are compatible.
  • 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.

v2.2

  • Added MacOS and iOS support
  • Improved GLSL2HLSL converter to fix multiple issues on GLES

v2.1.b

  • Removed legacy Visual Studio solution and project files
  • Added API reference

v2.1.a

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

v2.1

New Features

Core

  • Interoperability with native API
    • Accessing internal objects and handles
    • Creating diligent engine buffers/textures from native resources
    • Attaching to existing D3D11/D3D12 device or GL context
    • Resource state and command queue synchronization for D3D12
  • Integration 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
