This movie is a tool for augmenting presentations.  The quality of audio
visual aids in presentations has been enhanced with computers and user
friendly software.  POVRAY renderings can be impressive backup for anything
to do with marketing.

The model was built in Pro-Engineer, saved as 3dPaint (obj), I translated
most of the parts to with my own converter, but to uv map the logos it was
imported into Ultimate Unwrap 3d where it was exported as a pov smooth mesh
(the I could not acquire high resolution bitmaps for the logos as you will
see).

437 frames at 20frames/sec (200 megaHerz), rendered about 30/frame.   I am
still new at this, I haven't had the time to put a proper scenery in the
back ground.  I need to search the archives for time saving with radiosity.

It is long, so let the downloader beware (3.8 meg)

Please feel free to critique (like I'd have a choice anyway)

Hi,

It's a nice model. As you noted yourself, the background needs to be
improved. The sky is okay but the white ground is unpleasant for my eyes.
The logos may not be high resolution, but they look more jerky than I would
expect. Have you added "interpolate 2" in the  .. hmm how to say this, let
me show you:

pigment { image_map { tga "something.tga" interpolate 2 } }

If you already have this, I'd say a bigger logo resolution could do wonders
to the overall quality. Also, if you want a more realistic look of the
object, you could add more texture to it, such as bump-map, a bit of
reflection and a metallic pigment image.

You seem to have put a lot of time into converting the model to POV, but
regarding the UV mapping, in this case you only need cylindrical mapping
which is available natively in POV. You don't need UV mapping for this, even
on a mesh.

Radiosity is probably no help in your scene. If you decide to use it, I
suggest you add it as the last step, when you already have the rest in place
(the enviroment, ground, background)..

But, nice work.. Keep us updated.  ;o)

Regards,
Hugo

I'm not familiar with the interpolate 2  or what it does, I'll look at the
docs try and understand it and apply it.

The parts where already made in Pro Engineer, so that was irrelavant.
Finding a process to convert the files and put the uv mapping on was the
painful part.  Now that I understand the processes it doesn't take too long.

I'll try it that way.
