Thank you, Janek. May I know where can I find the marching cube algorithm in
YADE? And how is it used? I'm really curious (one reason is i've spent days
looking for the marching cube algorithm). Although I'm still a novice, but I
hope soon, I'll be a 'pro'. If I am able to think of a shape that can be
specified by an equation, and marching cube is available, it will save me a lot
of trouble thinking of how to plot it. Thanks~
Really grateful,
CW Boon
