Diligent Engine - v2.4

• Added explicit resource state transitions
• API Changes
  • Added RESOURCE_STATE enum that defines the resource state
  • Added RESOURCE_STATE_TRANSITION_MODE enum that controls resource state transition mode
  • Added DRAW_FLAGS enum that controls state validation performed by Draw command

  • Added IBuffer::SetState(), IBuffer::GetState(), ITexture::SetState(), ITexture::GetState() methods
  • Added IShaderResourceBinding::InitializeStaticResources() to explicitly initialize static resources and
    avoid problems in multi-threaded environments
  • Added InitStaticResources parameter to IPipelineState::CreateShaderResourceBinding() method to allow immediate initialization of static resources in a SRB
  • Removed default SRB object
  • Renamed/moved IBuffer::UpdateData() to IDeviceContext::UpdateBuffer()
  • Renamed/moved IBuffer::CopyData() to IDeviceContext::CopyBuffer()
  • Renamed/moved IBuffer::Map() to IDeviceContext::MapBuffer()

Diligent Engine - v2.3.b

• 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

Diligent Engine - 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:
