Argh, I'm gonna hate numbers... quad, triangolo and norm are very...

Hello Christoph! I'm going to have a look at megapov soon... it looks so 
darn cool.

Here's my plan:
finished model + some simple and fair textures + HDR background + 
megapov = boring photorealistic pic...

unless I have some more original ideas.

Oh hey.  That looks really great.  I should know, I happen to have that
particular Transformers toy.  I played with it so much when I was young,
all the joints wore down.

But yeah, it looks great.  Thanks for bringing back some memories.

Absolutely stunning! As I said you've got a talent for handling numbers,
though a headache is no surprise... :-)

The thing I've recently learned about rounded edges is, on a model this
complex, they will only be visible at high resolution or close-up shots.
Also, they may be almost invisible once you've added textures. That is,
assuming those textures are hand-made to somehow pronounce the edges, as
seems to be the usual case in proffessional work.

I must confess that I have changed my own strategy for modelling since I
found the freeware polygon-modeller Wings3D. I used to hate modellers for
their clumsy interfaces but this application is very intuitive and changed
my mind. So I model most objects there and take them into POV-Ray.

Hugo

JRG,
    Yeah, that was my favorite toy when I was a kid.  I brought it to
show and tell in elementary school at least three times.  And then it
broke.  It's very cool to see that it still exists in this world.  And
now we can do cool stuff with it in 3D.  Rule.  That's some nice
modeling, too.  I can't wait to see it completed.

Glad to see your making images again. This model is ***sick***. I've 
tried complex CSGs, but always abandon the projects due to long render 
times. What is the render time on this?

Hi Shay.
With radiosity and AA turned off it takes 40 s to render at 768x1024 on 
a humble 1 GHz machine.

It's a matter of avoiding unnecessary "difference", "intersection" and the
like. For example, imagine this model: A large box with 100 holes. In this
case you need CSG "difference" but the rendering will be slow, unless you
split up the large box into 100 smaller boxes, each with one hole in them.
If you don't do that, meaning if you stick with one large box with 100
holes, the bounding box of each hole will expand to fill the entire box. In
other words you are rendering 101 objects on top of each other, all over the
large box. Instead of having to render only 2 objects at a time .. small box
with a hole.

This kind of bounding troubles also arise when you nest objects by using
"merge" instead of "union".. And it's dangerous to nest several layers of
"difference" of course. My rule of thumb is to avoid boolean operations when
possible. This will make even complex CSG render just as fast as a mesh -
provided you stick with old fashioned primitives, not sphere_sweeps, iso's
etc...

Hugo
