Member Function Documentation

◆ GetMaxSize()

static constexpr uint32 FD3D11ConstantBuffer::GetMaxSize ( )
inlinestaticconstexpr

◆ InitRHI()

void FD3D11ConstantBuffer::InitRHI ( FRHICommandListBase &  RHICmdList)
overridevirtual

Creates a constant buffer on the device

Reimplemented from FRenderResource.

Reimplemented in FWinD3D11ConstantBuffer.

◆ ReleaseRHI()

void FD3D11ConstantBuffer::ReleaseRHI ( )
overridevirtual

Releases the RHI resources used by this resource. Called when leaving the state where both the resource and the RHI have been initialized. This is only called by the rendering thread.

Reimplemented from FRenderResource.

Reimplemented in FWinD3D11ConstantBuffer.

◆ UpdateConstant()

void FD3D11ConstantBuffer::UpdateConstant ( const uint8 *  Data,
uint16  Offset,
uint16  InSize 
)
inline

Updates a variable in the constant buffer.

Parameters
Data- The data to copy into the constant buffer
Offset- The offset in the constant buffer to place the data at
InSize- The size of the data being copied

Member Data Documentation

◆ CurrentUpdateSize

uint32 FD3D11ConstantBuffer::CurrentUpdateSize = 0
protected

Size of all constants that has been updated since the last call to Commit.

◆ D3DRHI
