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)?

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?

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.)

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

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.

Right - the tendency to "read through" stuff like that due to [over]familiarity
is why they always say to have someone else proofread your stuff for you.


> This one's on purpose.

There's a jarring "blip" around 9:18 where the eel kinda hits the water surface.
 I watched it in Media Player, but I remember seeing another very dark frame or
two in the weeds when I watched it with VLC.   Maybe it's more pronounced in one
than the other.  I'll have to see if I can watch it in 1/2 - 1/4 speed, or step
through it frame by frame.

It would be interesting to have an output statistic in POV-Ray which summed all
the RGB values of the pixels and then divided by the number of pixels to give an
overall "brightness" value.  It probably wouldn't add much to the render time
since it's rendering pixel by pixel anyway...

On this web page (That's all in french, but I 'try' to give explanations in
english below):
http://povray.free.fr/quatre/index4.html

Take a look at this part of the page at the bottom :






Here the author of this page says that if two materials (here, the mint syrup
and the glass) have some surfaces in common there will be black, gray or white
stains that will appear, the solution there is to apply a scale with the value
of 0.99 , 0.999 or something like that, to separate the materials. In your
example (the bathtub), you can apply that scale value of 0.999 and that 'should'
work. I'm not sure that this is the problem you're facing, but who knows ?

PS: I read the in between posts , but didn't find the above solution, so in case
that helps. ;-D

That would be the infamous "coincident surfaces" problem - but I doubt that
applies here.

There may be some other strange thing going on, but of course, without code, or
a detailed look at the rest of the scene - it's hard to know.

I'd isolate the bathtub and the light source in a separate [include] file and
render it in an animation with the camera looking at the tub, and going around
it in a circle.
