  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
 
(...) 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
 
(...) 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)
 
  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
 
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)

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 (...)

  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)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) L3P automatically moves the camera further away, please see (URL) is currently the way to go. I placed the "//orthographic" line in the camera setting only as a convenience if you want to experiment with that camera - you will have to adjust (...)

  Re: 2 Methods of Making CG Animations (was Re: LEGO animation software)
 
(...) I got this from Rolando (creator of LD4DModler) who is having trouble posting to LUGNET right now. Hello, for some reason I can't post in the newsgroup anymore. It nags about invalid newsgroups when I try to send a replay. Anyway I'am working (...) (21 years ago, 24-Jan-04, to lugnet.animation, lugnet.cad.ray, FTX)
 
  2 Methods of Making CG Animations (was Re: LEGO animation software)
 
--snip-- (...) Nope. =( It will render the animation in a movie file format (..mpg, .avi, etc..) when you are done. LD4DModler does not go the route of frame-by-frame animation as POV-Ray does, it uses 3D modeling. (The following text comes from a (...)

  Re: Simple POV-Ray Question - Perspective
 
(...) Here's what I use when I'm rendering parts: camera { orthographic sky -y right -4/3*x location <100,-60,100>*100 look_at <0,20,0> angle 1 } Change the location and look_at to suit your tastes. Note that I multiply the location by 100. I work (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) If you just do a straight "L3P model.dat," then you're right; the whole model fits very nicely in the camera's view (though a little fish-eyed, I find). But if you switch the view to orthographic, the model can appear a bit off-center and (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) As long as you let L3P calculate the camera distance, the whole model should be visible, and (mostly) fill the frame. I just copied the L3P auto-camera algorithm into LDView, and it works consistently for me with camera angles ranging from 0.1 (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: LEGO animation software
 
(...) Ahui showed me that site just the other day; that guy is wonderful. My brain hurts. I'd be very, very interested in seeing some tutorials on your animations, Steve. I watched your entire Brickshelf animation collection a couple days ago and (...) (21 years ago, 23-Jan-04, to lugnet.animation, lugnet.cad.ray)
 
  Re: LEGO animation software
 
(...) Hello I dont have much experience with writing programs. But I am working on writing a tutorial on how to make animations with povray using the clock, transform, and rotate commands. Maybe a couple of weeks. For now this is the best site I (...) (21 years ago, 23-Jan-04, to lugnet.animation, lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) I've run into this problem, and my caveman-sophistication led me simply to translate the object a little to put it back in line with the look_at coordinates. Even so, I often have to change the "PCT" value to 5 or 10 to accommodate all of my (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) Don't you then have to move the camera a ways back to get all your objects in the image compared to larger camera angles? This is what I tend to do, long ways away, small canera angle (anaogous to "telephoto" in real photogs, the images there (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) Using orthographic does not always work. You can get the same effect by seeing the camera angle to 0.1 Kevin (21 years ago, 23-Jan-04, to lugnet.cad.ray)
 
  Re: Simple POV-Ray Question - Perspective
 
(...) Just add the word orthographic. You may have to adjust the location. camera { orthographic location <708.303,-747.057,-563.561> sky -y right -4/3*x look_at <176.812,4.58475,-32.0701> angle 67.3801 rotate <0,1e-5,0> } Steve (21 years ago, 23-Jan-04, to lugnet.cad.ray)
