<div class="textblock"><p>SDF 布尔运算、修饰算子与域变形 </p>
<p>本文件提供三类操作：</p>
<ol type="1">
<li><b>布尔运算（CSG）</b> — 在距离值上执行组合逻辑</li>
<li><b>修饰算子（Modifiers）</b> — 对距离值做数值变换</li>
<li><b>域变形（Domain Deformation）</b> — 对采样点空间做几何变换</li>
</ol>
<p>所有操作遵循 SDF 惯例：对采样点或其距离值做变换后，保持 f&lt;0=内部、f&gt;0=外部的语义。 域变形算子应用到采样点（而非对象），因此位移/旋转方向与直觉相反（逆变换）。 </p>
