1.start from line polygon clipping,从最开始来说,应该是一条边(线)的两边有不同的处理方法,因此我们先从一条线开始分析。 首先是基于世界空间的计算: 这里要用dot product来计算,因为我们这里是2D vector,而cross product需要两个3D vector。 首先我们有两个点p0p1构成了一条线段,并生成 line dirction和line...
It'sthedotproductbetween thenormalvectorofaplaneandthevectoralongtheline. 这是平面法向量,和沿直线向量的点积。 open.163.com 4. AndIcanrewritethisinvectorformasthegradientdotproducttheamountbywhich thepositionvectorhaschanged. 可以把这些用向量形式重新写下来,就是梯度向量和位置改变量的点积。
The use of each term is determined mainly by its context. We say that vectors are orthogonal and lines are perpendicular. The term normal is used most often when measuring the angle made with a plane or other surface. Example: identifying orthagonal vectors Determine whether p=⟨1,0,5⟩...
In this article I describe an art-based procedure with a gradual sequence of drawing tasks that guides an art therapy client through graphic stages from point, to line, to plane. The client begins by making random dots, connecting them one to another with an unbroken line that reaches all ...
