  Re: Are the illustrations for the modeler's book series created with Ldraw compatible software?
 
(...) LGEO does have textured slopes, not mapped but calculated on the fly by POV. The effect is similar to that of the pics in the books. (...) I'm not sure what you mean by this (?) Here is more odd stuff: In "Lego City, The Ultimate Sticker (...) (22 years ago, 13-Feb-03, to lugnet.cad.ray)
 
  What's in a name... (was: Fog yourself)
 
Jan-Albert van Ree is of course called Jan-Albert and NOT Albert-Jan van Ree. Sorry Jan-Albert :-( (...) (22 years ago, 13-Feb-03, to lugnet.cad.ray)

(...) I don't think they used LDraw -- unless LGEO has textures mapped on sloped parts. Also, the tiles are grooved, LDraw's tiles weren't grooved in 1999. Steve (22 years ago, 13-Feb-03, to lugnet.cad.ray)
 
  Re: Are the illustrations for the modeler's book series created with Ldraw compatible software?
 
I must say that now I have the book in hand, the images are deffinately rendered. You can, like you said, cleary make that out from the shadows. I doubt though the used LDraw, for the book I have (Animals) dates back to 1999. One other possibility (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Level B Simplification - LDraw Boxer
 
(...) Clever idea. I don't know if you are interest by optimization. I suppose a brick is (xmin,xmax,ymin,ymax...min,zmax). I guess the most efficient data structure is octree. Octrees can be implmented as binary trees. On the first level you sort (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Level B Simplification - LDraw Boxer
 
(...) Thank you. Even if I were the only lugnut to benefit from the LDBoxer project, I'd still find it worth the effort. (...) Not the way you expect, I can tell! :o) I've made a pile of .nfo files to be copied into the Parts\B directory. For (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Fog yourself
 
(...) You are right off course. But the goal was to understand POV-Ray's fog. As I wrote in my PS: if you want real looking fog also include atmospheric media. (...) Thanx! Jeroen (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Level B Simplification - LDraw Boxer
 
(...) Just so you don't interpret the paucity of responses to indicate a lack of interest, let me say for the record that this sounds like a fantastic utility! I haven't had time to download and install it yet, but I will try to do so when I get (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Are the illustrations for the modeler's book series created with Ldraw compatible software?
 
(...) Hi Tim, One tell-tale sign is that the shadows on the ballerina are classic ray-traced shadows with sharp edges. Most 3D artists would actually not choose raytracing as their first option because a) it takes a lot more time than other shading (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
 
  Re: Fog yourself
 
I'm no expert so take my advice at face value, which = zero. I was taking a look at your ground fog renders and noticed something that I felt was odd. I would figure that if you were in a fog environment, then you would get no shadows or very faint (...) (22 years ago, 12-Feb-03, to lugnet.cad.ray)
