Normals are assumed to be associated with the front faces of a mesh primitive.
法线按假设是与网状结构基本型别的正面相关联。
Because normals are required and the array may have not been created before, there is always the possibility of a memory allocation problem.
因为法线是必须的但是有可能还未被创建，那里可能会产生内存分配问题。
If normals are not specified, their generation depends on whether the developer has specified triangle indices for the mesh.
如果未指定法线，则它们的生成将取决于开发人员是否为网格指定了三角形索引。
Also make sure the surface normals are pointing outwards.
也确定表面的法线指向外面。
A subgroup of 6 normals and 5 patients with a stable chronic cough had repeat automated measurements at least 3 months apart.
6名健康受试者和5名稳定的慢性咳嗽患者，间隔至少3个月后做LCM的重复测量。
Results: Compared with the normals in Beijing, the mandibles of the subjects were positioned more backward and rotated inferior posteriorly.
结果：同北京正常相比较，广东省双颌前突患者下颌骨位置相对后缩，向后下旋转。
Calculating local normals of vertex and polygons in an object and positioning another object according to it.
获取一个物体的顶点和多边形面的自身法线，并据此放置其他物体。
Do not weld vertices after you have updated the normals or smoothing groups of your objects, or the smoothing groups will be messed up.
更新完对象的法线方向或平滑组后，不要再合并顶点，这样会导致平滑组错误。
Faces also have normals ( perpendicular to it's plane) which is pointed in a direction, from which face will be visible to camera.
那些指出方向的面也是可以正常的（垂直于它的平面），将从相机中看到那一个面。
The faces are defined in terms of the vertices and normals of the mesh .
平面是根据网格的顶点和法线来定义的。
In this research we developed a method of using surface normals to determine the approximate boundary of roof planes.
在本研究以分析法线方向群集性来概略定出来决定屋顶平面近似边界。
Second, normals and curvatures of vertices in the optimal neighborhood are estimated by covariance matrix analysis.
然后运用协方差矩阵分析的方法，在最优邻域内计算出各采样点的法向量和曲率；
Things to check are un-welded vertices, overlapping vertices and whether surface normals are facing the right way.
需要检查没有焊接的点、重叠的点以及是否面法线的朝向正确。
Disables normals. Use this option if the mesh is neither normal mapped nor affected by realtime lighting.
禁用法线。如果网格既不是法线映射也不受实时照明的影响，使用此选项。
The adrenals usually appear normals , but occasional hemorrhages may occur in the cortex and medulla.
肾上腺一般正常，但皮质部和髓质部中间偶而也出现血。
First of all, the normals of the mix points are estimated by principle of mirror reflection.
首先，根据镜面反射的原理求出混合点的法线。
Default option. Calculates tangents and binormals. This option is available only when normals are either imported or calculated.
默认选项。计算切线和副法线。此选项仅用于法线选项是导入或计算时。
Enables or disables automatic normalization of vertex normals .
启用或禁用顶点法线的自动规范化。
The particles are automatically aligned to the object's surface normals .
粒子自动和物体的法线对齐成一线。
Short of getting a human involved to look at the model, there are ways to check that the normals are pointing outwards.
除了让人来分辨这个模型的正误外，还有另外一种方法判断平面的法向量是否朝向外面。
