Many thanks!
I am going to update!
Damn, a "bug"!!! :(
I noticed that the "real" labels for each mesh were lost in the final file I
posted!
I'm sorry because this makes the changes a bit more complicated.. I have to fix
it in the next items!
thanks!
G.

Done!
The new file is INC
But you have to remove the comment slashes at the end of the file, so you can to
see the preview!

thanks.  a nice car.  one (minor) gripe - the mesh resolution is very/too low, I
see "corners" even with the 'smooth_triangle's; attached.


regards, jr.

yes, I know, I use these objects to complete architectural landscapes and
usually I try to keep them light and fast. This one, however, as I wrote, was a
simple
conversion test by my tools of a web file by Sketchup, I didn't do anything
except eliminating wrong faces with zero area ... it is a small file
BR !

Even the finish is just basic, wanting to perfect it

Maybe I tell you things you know, but if you want to improve the mesh, which is
clean (and it's an advantage) you can use MeshLab, without going crazy by hand.
It has many remesh options, most of the time unsuccessful, some options can
work...
Mesh step Mesh otherwise you lose the colors

I like the cars, and so do the people. My expectation was not that I would be
able to zoom in properly. For reasonable scenes, you simply need many different
models, and the BMW in particular does really well.

The BMW, is that the final version?

I wanted to work on it somewhen in the next few days, split the meshes, change
Color and so on. This costs several hours, and I would not like to do it several
times for the same model.

Unfortunately, I don't know how to model, so I don't have any mesh products to
show. For me, everything consists of cylinders, boxes, spheres, with very lousy
textures around them.
We have to be that honest.

But my programming works fantastically ;)

Greetings, and I hope for more Cars and Persons.
Ma

Yes, you are right, it is a final version, because I have other cars and people
that I want to improve, and the BMW, although simple, is clean. Tomorrow I will
try to see if I can increase the polygons while maintaining the colors, in a few
automatic steps ... but I cannot guarantee, many transformations must be
crossed. I will let you know soon.
BR!

Unfortunately as I feared I tried with MeshLab to increase the resolution, but
it introduces errors.
As I thought it loses the border between the colors and also inverts (!!) some
faces.
This is the reason why I always work with my tools. I have an idea, in the next
few days I will implement a new feature. It takes the object and extracts the
files divided by color. In this way you can improve the parts that need it and
then it is easy to join them!
See you soon!
G.

I just had a look at what installing MeshLab would entail, but the above changed
my mind :-).

still, it's true when you write "...but if you want to improve the mesh, which
is clean (and it's an advantage)...", therefore I suggest:

> This is the reason why I always work with my tools.

if you can export a mesh to a GNU/GTS, that library has loads of tools to work
with clean (and not so clean :-)) meshes.

and this is where I cannot "follow", why "by color" ?  why not "by component",
and leave texture/colourising for when the object is used ?
