My first bathtub is going in the trash.  It is a superellipsoid 
differenced with another superellipsoid.

Strange artifacts are afoot.

The first picture, ttbo1030, I don't get what that weird shadow is on 
the sides near the middle of the tub.

The second pic, ttbo1040, I lower into the tub and the top of the tub 
gets all strange. It looks like the left wall is over the tub, and on 
the right side you can see white door under the top of the tub.

Oh well, boxes and cylinders for me.

On the plus side, I'm trying to push too much water through the faucet, 
so it bubbles up like a fountain.  It's broken physics but I really like 
the fountain effect, I think I'm going to keep it. :)

No idea.  Maybe look FROM that area TO the light and see what's there.

That almost looks to me like you differenced out a superellipsoid that's too
short and you have a very thin lip folding over the edge of the tub.
Can you visualize it by adding in the differenced SE with transparency or just
re-render it as a union (with different colored SE's)?

> Oh well, boxes and cylinders for me.
Or rounded_box objects in FL's shapesN.inc (which are the same thing, but in
macros ;) )

I had a look at your latest full movie.  There are a lot of impressive things
that catch my eye as a povver.

I'll leave the many good things for a different post - but there are a few blips
where maybe the whole frame is black when something overlaps the camera?  Can
you fix those with an insidedness test?  Maybe just write that frame number to a
file and use the one before or after, just to maintain timing with the audio?

Amazing work so far.   You've been at this for a LONG time, my man.  SO many
things going on in there.

What? Where? Did I miss any (eye) candy?

Oh yeah. I wish I'd thought of that when doing the pink soap bottle.
Prolly won't work for the tub since I have to slope the sides.

I think you mean like where the camera goes in and out of the fishtank?

>  Can you fix those with an insidedness test?

um...

Never!  That just violates too many scripting rules.  I'd be more apt to 
fix it, if I knew what you were talking about.

Thanks.  5 years + 10 years off + 5 years.

I started in 1999, so over 20 years. (1998 was the haus model. I needed 
to visualize for my wife what the home office over garage addition would 
look like before she'd let me build it.)

 >  SO many things going on in there.

Thanks.  I try to build it to require multiple viewings to see all of 
what's going on.  My two big successes there were the mushroom cloud 
explosion, and the SpaceLoco launch (my favorite scene).

I rewrote some of it for the "rounded_box" modification I made for a tabletop.
Maybe just edit the macro so that you can have top and bottom be different
sizes.  Might be easier than writing the whole CSG from scratch.
Isn't there also some kind of rounded pyramid / prism...?

Yes - there was that.

I just rewatched the whole thing:
there's a blip when entering the train for a ride around the track
one or more during the nuke cloud
and then one at the beginning of the flashlight scene in the tank

> >  Can you fix those with an insidedness test?

Yeah - nevermind.  With what you've got going on it would be a nightmare.

Well, I liked the unexploding text at the beginning.

And the way he has the camera avoid so many things that are waving and bouncing
around.  That likely takes some skill.

The inset during the train liftoff is pretty cool too  :)

I'm not seeing this.  It may be an illusion because the camera moves 
pretty quick for a couple of frames. ?

> one or more during the nuke cloud

Huh. There is an unexpected black frame here. Wild that I never noticed 
it before. :) :(  (I mean, how many hundreds of times have I looked at 
these individual frames...)

> and then one at the beginning of the flashlight scene in the tank

This one's on purpose.  I assume you mean where the kid looks at the 
flashlight and then turns it on.  I put a piece of glass in front of the 
camera so it would "blind" the kid.
