  Perhaps you are talking about polygons?
  Putting polygons on the x-y-plane and using an ortographic camera in the
-z axis looking at the origin should get a completely 2D-look.

Either that or 'image_map {tga "file.tga" map_type 0}'.
However, as Nieminen said, a 'orthographic' camera can rid any scene of a perspective
distortion.

  A little work with the scale function will flatten almost any object
you can make into a near 2d object. A box can even be specified as
a 2d object if your interested.

box {<-1,-1,0>,<1,1,0>}

A cone can be scale near flat like so

cone{<0,0,0>,1,<0,1,0>,0 scale <1,1,.001>}

  Other objects can be specified in a similar fashion to achieve
your "2D" objects.

  I am not saying that using the scale function is the perfect solution
but it does come close enough for the kind of work I do :)

Be careful of odd effects when scaling things very small or large or possibly even
thin
too. This last thing I have yet to see any problems with but you just never know, so I
thought I would mention this here.

  The same potential problems can be also be used for some interesting
special effects. I once used a mesh of a woman and gave it totaly
unrealistic porportions using the scale function. The distortion caused
by this was a very comical image when done. Someday I am going to make
a postable image exploiting this seldom used technique and you'll see
how magnificint it can be.

   Well let me just say that I believe many women are proportioned
very nicely, bless their little hearts, while others could benefit
from some serious rescaling efforts ;^ }

Thanks to all those who replied to my 2D question (and others)...
I'm certain, among all those great replies, I can find my answer !

 -----------------------------------------------------------------

  Here is my  M E S H  question:

  I haven't tried a "mesh object" yet... which seems to be able to
render any non-regular shape defined by...ummm... by what though ?  :)

  I'm assuming you need to write in the basic points defining  your
object... AND... tell it how smoothly or roughly to fill the spaces
in-between these defining points... am I close ?  

  I will look more carefully at the manual...but so far haven't seen
how these factors would be written in.

A mesh is simply a way of storing many triangles more efficiently.
Instead of #declaring a union of triangles, and having each copy use as
much memory as is needed to store the triangles(which can mean a lot of
memory with many triangles) you #declare a mesh, and copies of that mesh
only use enough memory to refer to that mesh.
In other words, a mesh is simply a union customized for storing large
numbers of triangles.

Agreed, my wife for one, a scale of <1.15,1.15,1.15> would make her
about 5' 6 1/4"
And yes, I did mean a uniform scale. [i.e the proportions are actually
fine until you place her next to other nearby
objects^H^H^H^H^H^H^Hpeople.]

And then there's Christine, who could really use a <0.3,1,0.3>...

Have Fun
