<div class="textblock"><p>SDF 到三角网格的转换 </p>
<p>使用 Marching Cubes 算法将隐式曲面（SDF）转换为显式三角网格。</p>
<h2><a class="anchor" id="autotoc_md30"></a>
Marching Cubes 算法</h2>
<p>在指定的包围盒内以固定分辨率采样 SDF 场，通过查表确定每个体素内的等值面三角形配置。</p>
<p><b>流程:</b></p><ol type="1">
<li>在 <code>[bmin, bmax]</code> 范围内构建分辨率 <code>res³</code> 的三维规则网格</li>
<li>在每个网格点求值 SDF</li>
<li>利用 Marching Cubes 查找表在等值面处生成三角形</li>
<li>返回包含顶点和三角形索引的 MCMesh</li>
</ol>
<h2><a class="anchor" id="autotoc_md31"></a>
注意事项</h2>
<ul>
<li>分辨率越高网格越精细，但计算量按 O(res³) 增长</li>
<li>推荐分辨率 64~256，取决于几何复杂度</li>
<li>结果网格需在 Marching Cubes 模块中定义（vde::mesh::MCMesh） </li>
</ul>
<p class="definition">在文件 <a class="el" href="sdf__to__mesh_8h_source.html">sdf_to_mesh.h</a> 中定义.</p>
