Copy full snippet

namespace FComputeShaderUtils {     FRDGBufferRef FComputeShaderUtils&58;&58;AddIndirectArgsSetupCsPass1D     &40;         FRDGBuilder & GraphBuilder,         ERHIFeatureLevel::Type FeatureLevel,         FRDGBufferRef & InputCountBuffer,         const TCHAR &42; OutputBufferName,         uint32 Divisor,         uint32 InputCountOffset,         uint32 Multiplier     &41; }

Remarks

Create and set up an 1D indirect dispatch argument from some GPU-side integer in a buffer (InputCountBuffer). Sets up a group count as (InputCountBuffer[InputCountOffset] * Multiplier + Divisor - 1U) / Divisor; Commonly use Divisor <=> number of threads per group.
