详细描述

CPU-side builder for GPU-driven indirect draws (stage 1).

Collects (instance, mesh, material, pipeline) tuples, sorts them by a 64-bit key (pipeline > material > mesh, stable by instance sequence), then merges consecutive equal buckets into one GpuIndirectCommand per bucket.

The caller writes the instance buffer in sortedInstanceOrder() so every bucket is a contiguous range; each command's firstInstance points at the bucket start in that buffer.

成员函数说明

◆ add()

void eve::graphics::IndirectBuilder::add ( uint32_t  seq,
uint32_t  meshId,
uint32_t  materialId,
uint32_t  pipelineId 
)

seq = monotonic instance sequence (stable order tiebreak).

在文件 IndirectBuilder.cpp 第 11 行定义.

◆ build()

uint32_t eve::graphics::IndirectBuilder::build ( const std::vector< GpuMeshRecord > &  meshTable)

Sort + merge. meshTable supplies indexCount/firstIndex/vertexBase.

返回
number of indirect draws produced.

在文件 IndirectBuilder.cpp 第 17 行定义.

引用了 a, b, idx, eve::graphics::GpuIndirectCommand::indexCount , 以及 m.
