Accordingly, if you want to map the lower left corner (-1, -1) of the cube's front face to the texture's lower left corner, you must assign the texture coordinates (0, 1) to vertex 0.
相应地，如果您需要将立方体正面的左下角映射到纹理的左下角，必须将纹理坐标(0,1)指派给顶点0。
Each face is an equilateral triangle and three faces meet at each vertex.
每一个面是正三角形并且于每一个顶点处有三个面相交。
This paper describes the error in focimeters, the principle of selection on curvature of inside face for vertex power of standard lenses and the method for measuring them.
本文叙述了焦度计的误差，顶焦度标准镜片内表面弯度的选择原则，以及标准镜片的测量方法等。
First we construct a generic face mesh which vertex number, vertex distribution, mesh topology and 2D parameterization are very suitable for the film visual effect field;
本文首先构造一个顶点数目、顶点分布、拓扑结构、二维参数化纹理坐标都非常适合影视特效中使用的三维人脸基本网格；
For a triangle in a given 3-d mesh, the order in which the triangle's vertex positions are specified determines whether the triangle face is a front or back face.
如果是指定的3 - d网状结构中的三角形，三角形顶点位置的指定顺序会决定三角形表面是正对面或背对面。
