| Hey all! I asked a similar question a couple of days ago, but I messed up the question so bad that even I didn't know how to answer it ^^ Anyway.. given the X,Y position of a sphere, how would you compute the rotations of this object if you were to move it around the x-y axis? I use this expression for figuring out how much to rotate it if I move it in just the X or Y, but both at the same time messes up the rotation. RotateX = sin(SphereX/(2*pi*radius))*360 RotateY = sin(SphereY/(2*pi*radius))*360 Anyone? |

| like this? http://www.blitzbasic.com/codearcs/codearcs.php?code=255 |

| There's ball rolling code in the code archives. And I think you mean XZ plane. :-) |
| ||
| yeah I probably mean that ^^ I get confused after working with 3DSMax for a while! ^^ I'll check it out, but I swear I scanned the whole code arcs.. :/ |

| Isn't a football a different shape than that of a normal ball? In this particular case, the only course of action would be to...er...go on a quest to...er...never mind. I quit. |
| ||
| that's the first thing I thought too,... then I realised I was being a silly American thinking football meant Football! :) |
| ||
| nope, this isn't what Im looking for.. I have to turn the ball in whole 360 degrees before I can "snap" i back into original rotation.. and yeah, its Soccer football not silly american football :) oh wait.. all football is sucky! Keep in mind I only need the actual rotation expressions as Im going to use it in 3DStudio Max.. |
| ||
| Well we have oval shaped American footy, and we have Oval shaped Aussie Rules Footy. I think you are outnumbered 2 to 1 :-) No help at all to your question but !! (:-( |
| ||
| hehe well thanks anyway for clearing that up ^^ |
