Hello,

 this is something that I could use and I'm sure other people could too,

I have the problem of not being able to visualize where things are in
relation to 0,0,0
and other items.my idea is a object like a plane devided into a grid marked
in pov units,
with 0,0,0 also marked, for example:

object{ grid
-1.0 / / same as for plane
 y    / / same as for plane
pigment{.....} / / the base color
pigment{.....} / / the line color
}
 it would basicaly be a plane but permanetely and infinately devided into a
grid.
render with it until everything is where you want it, then remove and use
whatever plane you want- if any. this could be done with an image maped onto
a plane, but it would take a verry big image to make this an infinite grid,
and actualy you could never do it this way without adding onto the image
every time you moved past a certain point. this could be helpful to newusers
until they get used to the way the xyz system works, and how things are
placed.

is/could this be possible?
does anyone else think its a good idea?

In the past there have been posted grid-textures that can do what you want 
(can't locate them at the moment). So no need for a new object.

What about something like:

#macro Grid(Pig1,Pig2,Size)
  #local Pig3=pigment{
    gradient z
    pigment_map{
      [Size/2 Pig2]
      [Size/2 Pig1]
      [1-Size/2 Pig1]
      [1-Size/2 Pig2]
    }
  };
  plane{
    y, -1
    pigment{
      gradient x
      pigment_map{
        [Size/2 Pig2]
        [Size/2 Pig3]
        [1-Size/2 Pig3]
        [1-Size/2 Pig2]
      }
    }
  }
#end

Grid( pigment{rgb 1} , pigment{rgb 0}, 0.1}

Send your sig to povray.binaries.scene-files and we can help you :-)

Why didn't I think of that......
man do I feel stupid......

Ok, anyone know where I can get one of these textures?

Gary
(who still thinks it was a good idea in general.)

Perfect!! how did you do that so quick?

I'll send my sig over when I get it the way I like it (estimated 4000 more
lines :-) )

    I use such things a lot. I have graphpaper with macros to make different
number of divisions, simple three pointed arrows with unit markers along
their length. A thin box with a unit sized checker pattern on it and a grid
of florescent buoys that float in space when I am doing a space scene.

I simply pigment a plane with the checker pattern (with different
colors).  It's scaled by 100 in each direction, because I model with
one unit = 1 cm.

Everything else I do on paper.

Thanks, I've always wanted to do that but haven't.
I fooled around with three dimensional matrices
but they didn't work very well.

I think when your Grid macro is used it should be:

Grid( pigment{rgbf 1} , pigment{rgb 0}, 0.1)

adding that one letter makes a big difference :-)
(and I don't mean correcting the typo }   ;-)

When I used POV for my math project, I created a "real" grid out of small
cylinders.  Quite effective, and the prof liked it too :)
