gaurav Posted February 5, 2012 Share Posted February 5, 2012 Hello Folks, How about mobius bands ? As usual most simple and obvious methods comes to me easily,this time 2 of them. How would you approach continues, Twisted surfaces in sop land ?? All ideas are welcome and your help is appreciated for my ambitious "10 year longterm plan" to master sops. Yes, Control over number of twists would be desirable. Quote Link to comment Share on other sites More sharing options...
Macha Posted February 5, 2012 Share Posted February 5, 2012 Oh oh, that shouldn't take 10 years! Try rotating vectors on a circle (uv texture it and use u) and then copy paste lines and skin them. That will give you a shitty version of a moebius band (the twist isn't so clean) but you should be able to fix that with a little thought in less than 10 years!

Time to rethink the strategy. I am moving on to the escher knots and staircases from next week.

Macha Posted February 6, 2012 Share Posted February 6, 2012 Another less useful but fun way to do is by creating a grid with uv coords. Fit u to 0..2*pi and v to -1..1 Now scatter points and use uv as parameters to calculate x,y,z according to x: (1+0.5*v*cos(u/2))*cos(u) y: (1+0.5*v*cos(u/2))*sin(u) z: 0.5*v*sin(u/2) You get a mobius shaded point cloud.

rdg Posted February 6, 2012 Share Posted February 6, 2012 Macha beat me to it. But if in doubt you can always refer to Paul Bourke: http://paulbourke.net/geometry/mobius/ Not sure what the hip contains, but I tried it once and it kind of worked. There's a movie somewhere, but I lost it. Quote Link to comment Share on other sites More sharing options...
