A few recent posts got me to thinking of this (again) and so I made a quick
little animation showing a fast trip from vicinity of Earth to the Sun.  It's
not much, needs a space craft or other diversions + about 1000 more frames to
be anything worthwhile.  Mercury and Venus are there someplace but are lost in
it all so don't even look for them.
I better explain some of it.  The Sun is a media filled sphere almost a POV
unit across, complete with flares and corona, but nothing science-fact.
Especially the journey at a speed I'd rather not calculate.  The camera starts
off slow and speeds up, although that doesn't really show in this.  I used the
equation out of C.C.'s  ClockMod include file to do acceleration of the
camera.
Enjoy the ride.

It's simple to find the speed.  The animation is three seconds long  and the
distance between the Earth and the Sun is 93 million miles.  Divide the distance
by the time and you get 31 million miles per second.  This is greater than c, the
speed of light, which is at 186,282 miles per second.  We were going backwards in
time.

As an afterthought, antimatter can be thought of as matter going backwards in
time, so did we get turned into antipeople?

Sure, but my brain is unwilling to think that out and my calculator is in the
other room.  Seriously though, I hadn't thought what the 60 frames at 24 per
second came out to exactly so I didn't bother.
I've made it easy on myself now and uploaded 240 frames of this to my
animations web page at:
http://members.aol.com/persistenceofv/anims.htm
so please have a look at it too, only about 50 times the speed of light now
and you can glimpse Mercury (or Venus, haven't figured out which yet)
streaking past at upper right at about the halfway point.
For the record, this was all just thrown together today from scratch while
trying a Venus and Mercury transit to check scales with reality.

Another reason to never time-travel.

I tried to view  solar ride  on you web page but it was only 27 kb.  Maybe it's
the sample image with the wrong extension.

Drat it all, okay, it's completely there now.  Apparently something went wrong
when using the AOL FTP, no surprise there.  To close the FTP I either hit
Continue to keep uploading other things or Cancel to stop and it must've still
been processing in the background when I quit the FTP.  Sorry.  You should be
able to D/L now.

Just to let you know that I looked at it. I didn't comment before because I
didn't feel there was much to say. Higher resolution and frame count would
help. Nice sun.

Have you have a chance to check out country_grass2?

Hey, thanks for watching it, "it" being the 10 second version at the web space
instead of this all too fast one here I hope.  Although there just isn't much
to it even if it were more frames than is now.  Could get boring without
something else added.

| Have you have a chance to check out country_grass2?

Seen it and rendered the tester2.pov.  Wish I had remembered to use the -UR
switch before I tried the "overkill" out.  I decided not to see it yet and
took a while to regain the memory back and even longer for the message stream
to repeat how it was removing unnecessary bounds.
That's about all I've done, read the script some and rendered a couple
examples to see it in action.  I don't know yet what Gilles Tran's or rather
Mick Hazelgrove's does as far as placement on things.  Haven't seen any of the
pov script.

Hmm, light travels to sun 8 minutes = 480 seconds, in your movie it
travels in 3 seconds, so speed is 480/3 = 160 c. Pretty impressive, I'd
say.

The last one I animated and uploaded (470KB now) to my web space:
http://hometown.aol.com/persistenceofv/solaride.mpg
 is 480 frames at 24fps but it plays here in MS Media Player just 14 seconds,
not 20 as I had expected.  Anyway, it's now about 36 * c average (starts slow
and ends fast) travelling a distance of 155.5 million kilometers.  If this
were to play for 20 seconds like it was supposed to then that would make 26 *
c instead.  Although, I'm not certain of this "average" speed due to the
acceleration involved.
That's still incredibly fast, but I have to admit the animation is getting
boring.
