Unless you chose otherwise at the time of setting up POV, running a .pov
file activates POV-Ray and opens the file. Then the macro program will push
<render>.

    We spent most of yesterday at Port Sebastian watching the edge of the
Hurricane. One of the reasons I asked this question was because I wondered
how far away you can see clouds from... turns out that it is quite far.
Using a correctly scaled earth and correctly located points on the earth, I
was able to see 10 mile spheres from over 150 miles away.

    Using reality to simulate POV I went to the beach. The edge of hurricane
Dennis was clearly visible, but without the knowledge that it was -possible-
to see it I would have just assumed that there were some clouds between me
and it. Having been raised in Florida I can tell when a hurricane is in the
area and for some time before we really felt the wind I was sure I was
seeing the storm.

    I am a hurricane lover and even now that I own property I would rather
have a hurricane than have safety. In fact I have been known to offend
people by expressing the opinion that if a big enough one came we would be
rid of all the condos and might even have a new port down in south Cocoa
Beach.... about where A1A comes back together....>8-}

One possibility would be to create response file, which contains
carriage return /newline and direct it as input to time command. I.e.
create text file nl.txt, which contains single newline. Now invoke:
time <nl.txt >time

BTW, if You have NT, then it has /T option, which just ouputs time:
C:\>time /T
16:15

 Sometime around 1978/79 I was setting up mobile homes in Colorado and
Wyoming. One early afternoon on a hill over looking Cheyenne Wyoming I
saw what looked like a column of smoke rising on the other side of town.
We were setting up a new 65' double wide mobile home on a custom lot.
As we watch another column of smoke dropped out of the clouds !!?
We watched as 5 more columns of smoke dropped out of the sky in a
matter of 4 minuets time with 7 all told visible at once.
 They were of course tornados forming from a major hail storm system
parked right over the town. I looked over at my co worker and pointed
out that we were on an exposed ridge, setting up large 15 ton empty
unanchored boxes, and that I was getting the heck out of there. He
agreed and we drove 50 miles south to where we lived and called it a
day. On the way home we ran through two hail storms the worst of which
had hail a bit larger that golf balls and it was like trying to drive
on a road covered with marbles of that size. I thought we were going
off the road a couple of times.
  Upon returning the next day we did not have to worry about finishing
the set up as the two halves of the trailers were scattered across 4
acres of field and smashed about as flat as if they had been run over
by a freight train. I can truely appreciate the power of major storm
systems but I'm also smart enough to get out of their way despite my
own fascination with them. I hope you too are as smart as I have been
and know when to run like heck when the time comes : )

    Sorry to disappoint you, I am one of those nuts who hide from the
evacuation cops. I've tried to surf in 115 mph winds (never did make it out
past the break). Me and my Lovely Wife sat out the last one on Cocoa Beach
when she was 7 months pregnant. We lived on Orlando Ave (which is two blocks
from the beach) and got 100 mph winds.

    I have also been known to chase tornados.

Chasing tornados is one thing. Having them chase you is an altogether
different story !

To keep it on topic I have tried modelling a tornado and have as yet not
even come close to getting it right. Even made an animation of one once
but it is difficult to control the shape and not have it look artificial.
Anyone else try this and have success ? I could post the anim if anyone
is interested.

    Oooo...  Tornado modeling......

    It's no wonder I never get anything done, I keep stopping to try
something else!

This works:

echo | more | time | find "Current"

I didn't invent this one myself; I picked it up from some "101 hints
for Windoze" article many years ago.

Okay, something that might help (seems all right) is being posted at
the p.t.s-f group, thanks to Ron P. for his command line to retrieve
"current" time. I had forgotten all about that little gem gleamed from
the masses of DOS stuff I have.

    Thanks! That works. I modified the batch file to self exit and called it
from the pov ini file and am now almost completely automated.

    If only the rest of the process worked as well...

Post a reply to this message

Well, I haven't had much luck calling POV-Ray to render and then
render a second time without error. Something about running
pvengine.exe (Win) instead of povray.exe (DOS) I think. A Ini file
can't be included on the command-line apparently. I was going to do it
all by using the batch file via Task Scheduler, which it does so fine
on one run only and using what Ini was previously set already, then it
does nothing on the second run. Other than that I've got a expensive
looking PC clock checker.
