表面的法线 meaning in English
normal to a surface
Examples
- Also make sure the surface normals are pointing outwards
也确定表面的法线指向外面。 - Note 2 : there is a specific case where coplanar / parallel surfaces ( that are very close to each other ) are acceptable , and that ' s when they have opposite orientations
注意2 ：只有在共面表面或近距离平行表面的法线方向不同时，才可以在模型中使用。 - Since displacement mapping is applied to the geometry of a surface , rather than to its shading , the normals of a displaced surface must be perturbed in tandem with the actual displacement in order for things to look correct in the render
因为置换贴图是赋予到一个表面的几何体上，强于赋到它的材质上，显示表面的法线必须用实际的置换来扰乱，为了在渲染时校正正确的外观。
