这个曲线与之前的数学图形(2.7)sphere sine wave很相似.而且个人觉得从其公式上看sphere sine wave更应该叫做球面正弦曲线.当然从渲染的曲线图上看,它是非常明显的贴在球上的正弦曲线. #http://www.mathcurve.com/courbes3d/sinusoidespherique/sinusoidespherique.shtml vertices = t = to (*PI) a = n = rand2() k = rand2() w = a/sqrt(…
查了半天也没搜到其具体的定义,先把脚本代码和截图发下. #http://www.mathcurve.com/courbes3d/cycloidspheric/cycloidspheric.shtml vertices = t = to (*PI) a = q = rand2() w = rand2(PI*0.1, PI*0.9) s = sin(w) c = cos(w) x = a*[(q - c)*cos(t) + c*cos(t)*cos(q*t) + sin(t)*sin(q*t)] z…
