Wow! You've certainly been busy. I especially like the playful-looking smoke
from the train's engine, AND the clever way you made the rocket (er, train)
exhaust as it launches and lifts into the sky. Your animated patterned-sphere
technique is looking better and better.

Well done!

(BTW, the video didn't come up immediately-- it was taking it's time loading or
something-- but on my 2nd try, I waited patiently and it finally showed up.)

I love this scene! I thought the locomotive would travel along the 
tracks but this is better. Well done. Cannot wait to discover the 
destination.

Thanks. I like that too. I hadn't thought of the term "playful-looking" 
but that's a good description. It is a bug that caused it to sputter, 
but I really liked that. (I underestimated MaxThrusts).

It is getting there. I think I need logarithmic curve for the 
fade-to-clear. .999 becomes .9999 becomes .99999 etc.

Very small km?

On the other side of that, I think it is 10km and hasn't even cleared 
the strongback.

I was worried you spacegeeks would freak out about that. :)

In my defense, in some reality, the SpaceLoco is being carried by the 
kid and is really no higher than an outstretched arm, 4 feet up. :)

The speedometer/tachometer sweep is what I used to see going from 0-100 
mph (in 6 seconds) on my CB650sc. Other than that I didn't put a lot of 
control into the numbers. I wasn't sure where they'd end up.  I will 
figure out what I want those numbers to be and backport the increments 
to fit. -- I just watched yesterday's SpaceX launch; I need to really 
dial back the altitude and increase the speed. :)


Major math disaster strikes!

So I have this 16:43 long song/movie.  I break out a scene of a couple 
of verses, between 1 and 2 minutes, and work on that.
The problem is, each scene can not end exactly on a frame, because I 
support 23.976 and 30 fps, and because I was a little sloppy. Each scene 
is +-0.5 frames off, which added up over the scenes. Even worse, in the 
movie, I have different start times for this scene depending on frame 
rate. :(  I am off by 0.126 seconds from where I think I am, which is 
horrible when trying to time it to music.

This is a cumulative problem, and I never really noticed it because most 
music cues happen on the peak of a sin curve, so if it is off by a 
little it's not really noticeable.  But, this scene, the countdown, 
monitor2 on and monitor3 on all need to nail the timing.  And in this 
scene as presented here, they do.  But, when I pasted it into the full 
movie, it is off by 0.126 seconds and they look horrible.  Even worse, 
this is 30 fps, and the 23.976 fps edition has a different amount of 
off-ness. [1]
So I have to do this scene in two different lengths. In the ini I pass
Declare=__FPS__=30
and adjust the duration and start time of the scene accordingly. :) :(
And, the Thrusts and camera2/3 images are handled by Java [2] and *it* 
needs to know the different scene durations and start times.  Just ugh.

At least at the end of this scene, my two timelines are resynced back up.


Math, and time, are most unforgiving mistresses.

I'm not real sure.  Do I go into space? Do I fly around the room? both?
I cut the next scene at 2:13, which is my longest scene, and I'm not 
sure what to do with it. :)

Just ignore them. No imagination at all. ;-)

In fact I think it is a brilliant feature. It throws people into 
confusion as they are caught by the action and forget the /reality/ of 
the playground. I was caught myself...

Of course!

Or not. There is a real nice feeling about going into space at a 
comfortable 40 km/h.

I guess the number or grey hairs on your head are increasing (or falling 
out instead) exponentially. :-)

I am sure all will be clarified in due time. I have full confidence on 
the issue.

Hmm, I used to drive Zürich to Basel at 140 km/h, so that number is 
significant to me, and it's 3 digits. So, that's my target. Thanks! :)
(Or maybe I'll stick to the posted speed limit of 120 ;) )

>> Math, and time, are most unforgiving mistresses.

Now that I've straightened this out, I wish I had done it sooner. The 
solution is separate ini files and different times for each edition 
(frame rate).  A tiny bit more tedious to set up, but way easier to 
manage and infinitely more accurate.

My Slovak stock is blessed with perdurable hair. And being blond, you 
can't even see the grey. :)

This is interesting (to me). For the first 5 years (1999-2003) I 
finished 1.2 minutes of animation a year.  The last 2.5 years since I 
picked this back up, my throughput is 2.1 minutes of animation a year. 
I have 5.5 minutes left to do.  If I can keep up this pace, I am 
targeting a Christmas 2020 finish date. :)

As a nitpicking realism fanboy, I advocate paying attention that the
altitude increases properly in accordance with the speed. Dunno if
that's currently the case for your video, just putting it out there.
