(...) You take the cross product of two of the sides of the triangle, this will give the vector perpendicular to the triangle plane: (URL) will point either upwars or downwards. Unless your triangle is in a known winding state there's no way to (...) (19 years ago, 28-Nov-05, to lugnet.cad)

I get the same error when I try to click on the voting page: (URL) It might dissapear when some entries are added... Btw, the guidelines of MOTM say that we should send in ldr, mpd or dats, and you will render them from three different angles.. Is (...) (19 years ago, 29-Nov-05, to lugnet.cad.dev.org.ldraw, FTX)

(...) Hi Niels, There isn't really a meaningful way to get an angle out of a plane defined by three points. What would the angle mean? The xyz, angle formula in MLCad just says rotate the vector angle degrees around the vector xyz but in the case of (...) (19 years ago, 29-Nov-05, to lugnet.cad)

(...) Heh, probably ;-) Well, perhaps I got the math part, and definition process a bit mixed up: I'd just like to have a program that, from a three coordinates on a plane, can give me a rotation vector+angle that I can enter in MLCad... And I'm a (...) (19 years ago, 29-Nov-05, to lugnet.cad, FTX)
