I'm looking for a Mesh2 file that uses all of the Mesh2 features. I am
playing around with writing a program to manipulate meshes and I'd like to
thoroughly check my parser code. Does anyone have a Mesh2 file like this on
a web site that I can download? Thanks.

Check this:
#version 3.5;
camera {
location <0.0, 0.5, -4.0>
direction 1.5*z
right x*image_width/image_height
look_at 0
}
light_source { <-30, 30, -30> color rgb 1 }
#local Texture1=texture{pigment{color green 1}}
mesh2{
vertex_vectors{
8
(x+z+y) (x-z+y) (-x-z+y) (-x+z+y)
(x+z-y) (x-z-y) (-x-z-y) (-x+z-y)
}
normal_vectors{
3
x y z
}
uv_vectors{
4
<0,0><0,1><1,1><1,0>

texture{pigment{color rgb 1}}

scale .5
}

Thanks, but I was actually looking for a good-sized Mesh2 (.inc?) file that
I can try to import into my program.

I don't understand what's wrong with my example? Just remove other components
like light and camera and write mesh2 to include file. I don't understand word
"good-sized". Showed mesh2 is completly right according to mesh2 specification
at http://www.povray.org/working-docs/id000165.html#6_5_2_4 .

There is nothing wrong with your example. I'm just not expressing myself
clearly enough. Ideally what I would like to find is a mesh2 (preferably
closed, but not necessarily) of some recognizable shape and with a triangle
count of at least 500. Something like an ice cream cone, or a hammer, or a
tree, or an apple, or a ... :-)
I have already created my own small meshes to test my import code. Now I'd
like to try importing someone else's large mesh.

... two flying rectangles ? ;-)

But how my example works with your parser ?

Have you checked http://www.stmuc.com/thbaier/products.html and some large free
models from net libraries ?

Here's a simple little 'cherry' for you to play with 595 faces and UV

Hi Cris,
You're not writing the same kind of program as I am, are you? I thought I
could patent my idea and fill a gap in everyones POV experience.. Well.. At
least I'm struggling with math these days, reading and thinking, to get up
on the level I need for my things to work.. I'm interested in knowing what
you are trying to make? Maybe we could cooperate. Though, for now my plans
are secret, in case I do have something unique in mind, that I can develop.
Regards,
Hugo

You are aware that software patents are one of the purest forms of evil,
right?
