详细描述

CPU preprocessor that builds a Nanite-style hierarchical cluster DAG from a triangle mesh:

  1. Meshletization (LOD0): greedily partition the mesh into connected clusters of ~maxTrianglesPerCluster triangles (cache-friendly).
  2. Hierarchical LOD: iteratively merge clusters into parents and simplify each parent with a Quadric Error Metric (QEM) edge-collapse, building a cluster DAG with per-cluster bounding spheres + geometric error.

Pure CPU, dependency-free, unit-testable.

成员函数说明

◆ build()

bool eve::virtualgeometry::VirtualGeometryBuilder::build ( const MeshInput &  in,
const Options &  opt,
VirtualGeometryAsset &  out 
)

Returns false on empty/invalid input.

在文件 Builder.cpp 第 337 行定义.

引用了 c, eve::virtualgeometry::VirtualGeometryAsset::clusters, error, eve::virtualgeometry::VirtualGeometryBuilder::MeshInput::indexCount, eve::virtualgeometry::VirtualGeometryBuilder::MeshInput::indices, eve::virtualgeometry::VgCluster::lodLevel, eve::virtualgeometry::VirtualGeometryBuilder::Options::lodTargetRatio, m, eve::virtualgeometry::VirtualGeometryBuilder::Options::mergeFactor, eve::virtualgeometry::VirtualGeometryBuilder::Options::minLodLevels, eve::virtualgeometry::VirtualGeometryBuilder::MeshInput::normals, eve::virtualgeometry::VirtualGeometryAsset::normals, parent, eve::virtualgeometry::VirtualGeometryBuilder::MeshInput::positions, eve::virtualgeometry::VirtualGeometryAsset::positions, eve::virtualgeometry::VirtualGeometryAsset::triangles, eve::virtualgeometry::VgCluster::triCount, eve::virtualgeometry::VgCluster::triStart, v, eve::virtualgeometry::VirtualGeometryBuilder::MeshInput::vertexCount , 以及 eve::virtualgeometry::VirtualGeometryAsset::vertexCount.

被这些函数引用 eve::virtualgeometry::VirtualGeometryRenderer::build().
