calculate_dispatch_size()

std::array< uint32_t, 3 > MayaFlux::Yantra::TextureExecutionContext::calculate_dispatch_size ( size_t  total_elements, const DataStructureInfo &  structure_info  ) const

inlineoverrideprotectedvirtual

Derives dispatch size from the staged container dimensions when available; falls back to element-count dispatch otherwise.

Reimplemented from MayaFlux::Yantra::GpuDispatchCore.
