Member Function Documentation

◆ GetKeyBufferUAV()

FRHIUnorderedAccessView * FParticleSortBuffers::GetKeyBufferUAV ( int32  BufferIndex)
inline

Retrieve the UAV for writing particle sort keys.

◆ GetSize()

int32 FParticleSortBuffers::GetSize ( )
inline

Get the size allocated for sorted vertex buffers.

◆ GetSortBuffers()

FGPUSortBuffers FParticleSortBuffers::GetSortBuffers ( )

Retrieve buffers needed to sort on the GPU.

◆ GetSortedVertexBufferRHI()

FRHIBuffer * FParticleSortBuffers::GetSortedVertexBufferRHI ( int32  BufferIndex)
inline

Retrieve the sorted vertex buffer that results will always be located at.

◆ InitRHI()
