Thanks. Meanwhile, I actually applied many changes, with the effect that
scene parsing ends with an error. I tried to incorporate all advises,
but still miss something.

I am going to post the changed scene code at the very end of this
thread, to keep you all updated.

Do the changes one at a time and test if they work before going on to 
the next. Otherwise it is like trying to find two matching ends in a 
plate of spaghetti. :)

I like that description, and spaghetti.

I didn't get any errors after making sure all lines of SDL are commented, mostly
the several

//
--------------------------------------------

however, that's with my own image/bump file.
Probably need to use forward slashes, not back slashes since those are also
escape characters.

Rendering with a more distant camera I see the parachute piece again, that's
because in the LowerBalloonShape the cylinder being differenced away from the
sphere doesn't encompass the entire upper half.
Which is why I used:

 cylinder { < 0.0, 0.0, 0.0 >, < 0.0, MyRadius+0.001, 0.0 >, MyRadius+0.001 }

instead of 175.001 for y.

Only my opinion but I still think the torus balloon top has a better look if
making it
scale <1, 0.75, 1> instead of the flattened <1, 0.5, 1>
but that's all up to you.
Although, if doing like I did, those bump_map entries are required to be either
0.175*1.5 or the equivalent of just 0.2625.

Anyway, I'm sure you get the idea how to rescale the gradient if making any
changes to the object scale.

And once again, I'll say the widest part of the balloon gets smooth with this
way of going about using a map_type 0 (planar) mapping. But to do it with
map_type 1 (spherical) you need an entirely different image, one that isn't
patterned radially. Something with vertical features.

It should never be too late. Any sort of version control is better than 
none.


I assume you pressed the wrong button

BTW Put more tobacco in them. ;)

Yoiks! Forgot to say what I was going to tell about before starting to write
that last reply.
I blame Stephen for making me lose my train of thought with that perfect
metaphor about finding errors.  LOL

Sooo... bump_size 0.1, apparently that's too much. I tried 0.01 instead and
think it looks better. I realized the scale in the normal statement being
MyRadius*2 is probably the equivalent of bump_size 4 even if starting with 0.01.

Don't want to go into all that here but I recall many discussions long ago about
attempts to keep things such as normal and media from scaling up or down with
object sizes after placing the texture. Or just to be aware of the possible
ramifications when scaling.

That aside, please be sure to read my previous reply about the other things.

Ho, can you publish here the entire scene code of your version of the
scene? That would help me better to see the differences and to understand.

I admit, another problem I have, is based on the English language. Yes,
i understand it well, I even live in an English-speaking country now.
But I am not natively English-speaking. Reading all that English here,
causes a concentration problem for me, and I am always missing a lot of
things, not capturing them somehow. That is why I want to ask you all
here, to be patient with me. :-)
