How do I use POV-Ray

[Risbinroch]

aaglo: you help is really appreciated here. Why didn't the clipped_by statement work well? Can't understand why the shape looks like that?

 

[Gogf]

Thanks . I don't really understand the intersection, but by the time I need to, I probably will.

 

[aaglo]

the clipped_by -function does just that. It does not make a new surface to the cutted object - it makes the cutted object like... hollow.

See the image
#1 union of three spheres modified with clipped_by -function

#2 merge of three spheres modified with clipped_by -function

#3 union of thee spheres modified with intersection -function. Notice, that the result of using intersection on unions and merges are identical.

Thanks, alot, guess it can be useful in other circumstances, for instance a ships hull or something.

I like this program thanks to whoever posted the link earlier in the topic. BTW what do you think of my first non-tutorial work:

 

[Gogf]

It's good.

I dont really understand how to make these checkered floors, but it must be in a later tutorial.

 

[The Slayer]

no, you write something like

pigment { checker color Red, color Green }

 

[Risbinroch]

Anyone btw, tried Wings 3D, free program, that exports to pov-ray with a plug-in...?

I tried it out for some hours, quite easy actually, allthough I guess you must export to povray for texturing and such at least?

 

[Gogf]

I tried Moray (must be somewhat similar to Wings 3D) a long time ago, and it was pretty easy. I would rather be able to edit the raw code though.

@Slayer: Where do I put that to make it the floor (I doubt I will use it, but I might)? I assume you can also make a pure red floor, for example.

You need to make a plane at y=0 or something like that

Treads:

Im getting the hang of this:

For those who want to see my pov file here you go:

 

[Risbinroch]

Here is what I use now:

plane {
y, 0
pigment { checker color Magenta, color Green scale 10 }
}

And I think it has to be included, you would have to have a plane if you want the future-unit-to-be to cast shadows at least...

How did you make the tracks? I looked through the file put I couldn't find how you did it.

Wow, very nicce vbraun! How do you make the treads?

 

[vbraun]

Try this:

#declare insidet = difference{ box {
  <0, 0, 0>  // one corner position <X1 Y1 Z1>
  < 10,  2,  2>  // other corner position <X2 Y2 Z2>
}
// Capped Cylinder, closed [or open ended]
// cylinder { <END1>, <END2>, RADIUS [open] }
//  END1 = coord of one end of cylinder
//  END2 = coord of other end
// RADIUS = size of cylinder
// open = if present, cylinder is hollow, else capped
cylinder {
  <1,1,-0.1>,  <1,1,2.1>,  .9
  // open
}cylinder {
  <9,1,-0.1>,  <9,1,2.1>,  .9
  // open
}box {<1,.05,-1> <9,1.95, 3>}   }

#declare outsidet = union{cylinder {
  <1,1,-0.1>,  <1,1,2.1>,  1
  // open
}cylinder {
  <9,1,-0.1>,  <9,1,2.1>,  1
  // open
}box {<1,0,-1> <9,2, 3>} }

#declare tread =  
intersection{
object {outsidet}
object{insidet} 
}

Nice, did you do it with a box with sphere cut outs?

 

[the mormegil]

My first attempt:

What do you think?

 

[the mormegil]

AARRRRGHHHH! The dreaded red cross!

I'll try again:
