If the last vertex is identical to the first vertex, it is a closed form and the polyline forms a polygon. 如果最后的顶点与最初的顶点重合,它就是闭合的,也就形成了一个多边形。
To define the first triangle, we therefore provide vertex indices 0, 1 and 4. 定义第一个三角形,然后设置顶点索引0,1,4。
First, this algorithm assembles task vertex with similar attribute to form a bigger new task vertex based on K-means clustering, and then partitions hardware / software based on simulated annealing algorithm. 算法首先将有相似属性的任务节点通过K均值聚类算法组成一个大的任务节点,而后使用模拟退火算法划分由大的任务节点组成的系统。
First, calculate the vector between the vertex in it's world position and the light position. 首先,计算顶点在世界位置及光源位置之间的矢量。
First, the model is transformed into a vertex design by means of a transformation, and a simple variable matrix and a variable function are given. 首先通过一个变换,将模型转换成一个顶点设计问题,从而构造一个简化了的方差矩阵,求得方差函数。
