FRawIndexBuffer16or32::FRawIndexBuffer16or32 ( )
inline

Member Function Documentation

◆ CacheOptimize()

void FRawIndexBuffer16or32::CacheOptimize ( )

Orders a triangle list for better vertex cache coherency.

◆ ComputeIndexWidth()

void FRawIndexBuffer16or32::ComputeIndexWidth ( )

Computes whether index buffer should be 32 bit

◆ ForceUse32Bit()

void FRawIndexBuffer16or32::ForceUse32Bit ( bool  bIn32Bit)
inline

Forces (or not) usage of 32 bits indices. No validation is made as to whether Indices can all be stored in 16 bits indices (if bIn32Bit == false) or not : use only if you know the max value in Indices, otherwise, use ComputeIndexWidth

◆ InitRHI()

void FRawIndexBuffer16or32::InitRHI ( FRHICommandListBase &  RHICmdList)
overridevirtual

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

Reimplemented from FRenderResource.
