Diligent Engine - v2.4.g

API Changes

• Enabled ray tracing (API Version 240080)

• Added IDeviceContext::GetFrameNumber method (API Version 240079)

• Added ShaderResourceQueries device feature and EngineGLCreateInfo::ForceNonSeparablePrograms parameter (API Version 240078)

• Renamed USAGE_STATIC to USAGE_IMMUTABLE (API Version 240077)

• Renamed static samplers into immutable samplers (API Version 240076)

  • Renamed StaticSamplerDesc -> ImmutableSamplerDesc
  • Renamed PipelineResourceLayoutDesc::NumStaticSamplers -> PipelineResourceLayoutDesc::NumImmutableSamplers
  • Renamed PipelineResourceLayoutDesc::StaticSamplers -> PipelineResourceLayoutDesc::ImmutableSamplers

• Refactored pipeline state creation (API Version 240075)

  • Replaced PipelineStateCreateInfo with GraphicsPipelineStateCreateInfo and ComputePipelineStateCreateInfo
  • Replaced IRenderDevice::CreatePipelineState with IRenderDevice::CreateGraphicsPipelineState and IRenderDevice::CreateComputePipelineState
  • pVS, pGS, pHS, pDS, pPS, pAS, pMS were moved from GraphicsPipelineDesc to GraphicsPipelineStateCreateInfo
  • GraphicsPipelineDesc GraphicsPipeline was moved from PipelineStateDesc to GraphicsPipelineStateCreateInfo
  • pCS is now a member of ComputePipelineStateCreateInfo, ComputePipelineDesc was removed
  • Added IPipelineState::GetGraphicsPipelineDesc method

  Old API for graphics pipeline initialization:

  PipelineStateCreateInfo PSOCreateInfo;
  PipelineStateDesc&      PSODesc = PSOCreateInfo.PSODesc;
  
  PSODesc.GraphicsPipeline.pVS = pVS;
  PSODesc.GraphicsPipeline.pPS = pVS;
  // ...
  Device->CreatePipelineState(PSOCreateInfo, &pPSO);

  New API for graphics pipeline initialization:

  GraphicsPipelineStateCreateInfo PSOCreateInfo;
  // ...
  PSOCreateInfo.pVS = pVS;
  PSOCreateInfo.pPS = pVS;
  Device->CreateGraphicsPipelineState(PSOCreateInfo, &pPSO);

  Old API for compute pipeline initialization:

  PipelineStateCreateInfo PSOCreateInfo;
  PipelineStateDesc&      PSODesc = PSOCreateInfo.PSODesc;
  
  PSODesc.ComputePipeline.pCS = pCS;
  // ...
  Device->CreatePipelineState(PSOCreateInfo, &pPSO);

  New API for compute pipeline initialization:

  ComputePipelineStateCreateInfo PSOCreateInfo;
  
  PSOCreateInfo.pCS = pCS;
  Device->CreateComputePipelineState(PSOCreateInfo, &pPSO);

• Added ShaderInt8, ResourceBuffer8BitAccess, and UniformBuffer8BitAccess device features. (API Version 240074)

• Added ShaderFloat16, ResourceBuffer16BitAccess, UniformBuffer16BitAccess, and ShaderInputOutput16 device features. (API Version 240073)
