这是一个项目时使用到的“三维空间向量/点”类及相关函数,使用它们可以定义一个空间向量/点,实现向量的平移,缩放和旋转等,使用相关函数还可以实现两向量的叉乘,得到一个向量的绝对长度,将一个向量单位化,得到一个三点决定的平面的垂直向量(经过单位化),得到空间中两点的距离,得到两向量的点积,得到两向量的夹角等操作,为方便用户的使用,每个函数都有详细的注释,希望对大家有所用处. -This is a project to use to the " three-dimensional space

这是一整套数学库，包含了向量、矩阵及二维距离、三维距离、二维相交、三维相交的若干问题。-This is a set of math library, contains a vector, matrix, and two-dimensional distance, three-dimensional distance, two-dimensional intersection, three-dimensional intersection of a number of issues.

Calculate the distance of a given point P from a triangle TRI. Point P is a row vector of the form 1x3. The triangle is a matrix formed by three rows of points TRI = [P1 P2 P3] each of size 1x3. dist = pointTriangleDistance(TRI,P) returns the distanc

三维图形的处理，包括简单的叉积，点积，以及向量的旋转，对称和反射，点到面距离，投影，等等。-Processing of three-dimensional graphics, including simple cross product, dot product, as well as vector rotation, symmetry and reflection, point to surface distance, projection, and so on.
