  A different simple question
 
Hello all you super-smart PoV-Rayers out there, I've been fooling around with some simple animation the past few days and for some reason I can't seemt o be able to do what I want. I have a bowl-ish shape (thanks Michael L. for the generator in (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray, FTX)

(...) Can you make the .ini file you are using available as well? -Orion (21 years ago, 29-Jan-04, to lugnet.cad.ray)
 
  Re: A different simple question
 
In lugnet.cad.ray, Orion Pobursky asked: (...) Sure. I was simply modifying the main .ini file, so here's what I put in it: Initial_Frame = 1 Final_Frame = 402 Cyclic_Animation = on Initial_Clock = 0.0 Final_Clock = 1.0 All that appended to the end (...)

  Re: A different simple question
 
Hi I think that this is caused by the fact that the original MLCAD model is not centered in the virtual space. If you move it so that it's center is at 0,0,0, the camera will rotate around it. /Not 100% sure but I did replicate the above using a (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray, FTX)
 
  Re: A different simple question
 
(...) Hello Mike Glad to see someone starting into animation. Here are some changes I made to your file. first translate the bowl: translate<-400,0,-400> this will put it at 0,0,0. Second I simplified your Camera definition. Much easier to use. (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)
 
  Re: A different simple question
 
(...) You are rotating the camera around the y-axis! You would like to rotate it around the vertical axis through the bowl's center. Translate the model center to origo, rotate, and translate back again: translate -<400,-54,400> rotate (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)

(...) I am most definitely leaving myself out of that category. Especially after I see the stupid questions I'm going to have to ask here. (...) I thought that was what I was supposed to do...? (...) Right. I thought that's what rotating through the (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)
 
  Re: A different simple question
 
(...) I'll try to explain it, but it's kind of a difficult concept to explain without pictures. Note that my explanation isn't based on POV, it's based on 3D computer graphics in general. In the real world, when you rotate something, you rotate it (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)
 
  Re: A different simple question
 
(...) [Lightbulb pops on] Aaaahhhh!! :) Now it all makes sense. So when the original model was created, it must not have been at <0,0,0> in MLCAD. With that in mind I checked out the coords and you all are absolutely right. I picked out one of the (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)
