I know, just tried to use an isosurface for my ice floes, cancelled the first
render... Of course that's extreme because of Rune's quite complicated
construction.

I'm envious.  That was going to be my 4th guess (I'm lying).  Just now going
to get a cable modem and quit the satellite TV.  That wireless stuff will
probably be available soon after I get familiar with cable. Sarcasm
intended.

I put another animation at http://members.xoom.com/omniverse/mtnlakes.mpg
and it's just a tiny 180x90 res., but 320 frames.  The odd resolution is
incompatible with CMpeg (or my media players) so it's rough around the edges
but a good file size at 704KB.  Would have been 950KB posted here so I
thought it best to upload to the web space.
Things to note about it:  a mysterious lake depth change occurs near the
beginning.  Only the texture is scaled but neither the plane that makes the
water surface nor the isosurface has a scale in it themselves.  Not a clue
as to why this is.
This animation is doing a time-lapse sort of thing with snow and vegetation
changes which might not be too noticeable at first.  I've got to get a
spline path put in!  The camera is not moving too well yet.
Enjoy it for what it's worth.

Looks great, esp. the last part.

For showing the change of ice/vegetation, a sequence with stationary camera
would be good.

I gave up on that idea.  Always moving along to the next thing  :-)

A true pioneer work back in 2000... and today, 16.5 years later I would 
like to ask you whether I may convert it in a way that my Commodore 64 
and/or Atari 1040 STFM would be able to display it! At a mere 160 by 96, 
I would even have to scale it *up* to have it fitting into the C 64's 
multicolor mode, as my pre-GEOS C 64 does not have any window manager 
(and I have no experience yet in interrupt demo programming). Currently 
I am not sure whether the C 64's floppy drive actually would be able to 
stream it in full length - I probably would have to add a second VC 1541 
floppy drive (or go for the fabulous 1-megabyte SFD-1001, but the chance 
of finding one seems next to zero...).

However, on the Atari ST with its 720 kilobyte diskettes, it probably 
would run nicely in a TOS window, be it in monochrome, 4-color or 
16-color mode.

Regardless of all these pre-considerations, I firstly would simply 
convert it to color depths that just look like those native classic 
computer modes, but run on a modern-day PC, so I might publish it 
directly here without having it to video from the C 64's or Atari ST's 
screen...

See you in Khyberspace (which might also incarnate in an "AtariSTan" or 
even "Amig(h)anistan" version)!

Ahhh nostalgia... that sure is going back in time. Go ahead and good luck!

I tried to find the file that creates the animation to give you and I have a
ridged multifractal mountains and lakes scene from the following year. I had
added a flying car.

There's a problem with it. MegaPOV 0.7 was used and it refuses to render the way
it is now with MegaPOV 1.2.1.
I probably have the older versions archived away, no idea where though.

If I knew how to correct the reflection and slope texture_map statements I would
know for certain if this was the file.

I will go ahead and post it to the binaries scene-files group anyway. Maybe it
can be used somehow. It requires Chris Colefax's Clockmod.inc, too.

A wild ride in POV-Ray air over the mountains and lakes.

The original (or close to it) is now partially updated to POV-Ray 3.7, this low
resolution short animation is from the latest file posted at
binaries.scene-files:

http://news.povray.org/web.589c7136c3d0ae5d9c5d6c810%40news.povray.org

Be sure to read the other messages there, camera view is erratic due to what I
guess was my attempt to show multiple camera angles. Took 50 minutes to render
150 frames at 320x240 with my i5 processor @ 3.4GHz.

New and improved, and maybe that's saying too much. LOL

Too large a file for here, almost 7 MB.

https://youtu.be/aLwYm9aBQ80

Still a wild ride because of a crumbling natural bridge fly-thru, and my sloppy
attempt at slowing the flight at that point in the animation. I messed up the
cubic spline path there, it was supposed to move slowly past the natural bridge.
Timed it wrong.

No worries, you can retry it yourself. Posting the updated scene file at
binaries.scene-files once again. Better clouds in motion and casting shadows.
Although parameters are minimal quality, for isosurface too, for faster frame
rendering.

At least I got rid of the annoying camera discontinuities caused by adding
different vectors together from one clock range to the next, see previous SDL.

This particular animation, 320X240 and 600 frames with default antialiasing,
took about 10 hours on a i5 processor @ 3.4GHz.
