曲線公式分為2類

1、曲線公式分為2類，一類是2D的，另外一類是3D的-希望吧友把你知道的，覺得非常有用，或非常經(jīng)典的曲線公式共享出來-帖子最好能附上：公式+公式形成的圖片Xt=(67.5+3.5*cos(t/.24)+0.03*sin(t/.24)*cos(t)Yt=(67.5+3.5*cos(t/.24)+0.03*sin(t/.24)*sin(t)Zt=20*cos(t/.24)t1=0t2=11.9999*PIXT=100*sin(t)*cos(pi/20*(cos(16*t)-1)YT=100*sin(t)*sin(pi/20*(cos(16*t)-1)ZT=100*cos(t)t1=0t2=piXt=5
