The meaning of VECTOR PRODUCT is a vector c whose length is the product of the lengths of two vectors a and b and the sine of their included angle, whose direction is perpendicular to their plane, and whose direction is that in which a right-handed screw

在Unity3D中,Vector3.Dot表示求两个向量的点积;Vector3.Cross表示求两个向量的叉积。 点积计算的结果为数值,而叉积计算的结果为向量。两者要注意差别开来。 在几何数学中: 1.点积 点积的计算方式为: a·b=|a|·|b|cos<a,b
Vector3类详解,作者:隨意的風 一、向量、点乘、叉乘的介绍在数学中,几何向量(也称为欧几里得向量,通常简称向量、矢量),指具有大小(magnitude)和方向的量。向量可以形象化地表示为带箭头的线段。箭头所指:代表向量的方向;线段长度:代表向量的大小。向量向量
The meaning of AREA VECTOR is the vector of a plane surface whose magnitude is the area of the figure and whose direction is that of a perpendicular to the plane of the figure.
性质1: c⊥a,c⊥b,即向量c垂直与向量a,b所在的平面 。 性质2: 模长|c|=|a||b|sin<a,b> 性质3: 满足右手法则 。从这点我们有axb ≠ bxa,而axb = – bxa。所以我们可以使用叉积的正负值来判断向量a,b的相对位置,即向量b是处于向量a的顺时针方向还是逆时针方向。
Cross:向量叉乘 Dot:向量点乘Lerp(v(from),v(to),t):两个向量之间的线性插值。按照数字t在from到to之间插值。MoveTowards(v,v,speed);当前的地点移向目标。RotateTowards(v,v,r,m);当前的向量转向目标。Max(v,v),Min(v,v);向量的最大值,最小值 ...
