This is a first draft of an image created using a macro I created, based
heavily on Glenn McCarter's interlace code from his Winseat image in the
previous IRTC round. The space image was created with Chris Colefax's galaxy
include. The planet is my own.
The image depicts an image received from a satellite that will be sent out
in the future. It took years for the images to get to earth. But now it is
obvious that it was worth the wait...
Please let me know if you have any ideas on how to improve the image, be it
from the space image point of view, or the TV interlacing effect. I realize
that it is quite likely that by the time these images would get back to us,
we would no longer be using TVs so the interlacing effect may well be
eliminated but humor me on this. :)

Wonderful love the interlace affect.. I also would like to know how this was
done...?

How would we replace Americas fav. pastime VR? Or little TV Glasses...

From an astronomical point of view, the light source ought to be much
further from the planet. I'd suggest a distance of about 10000 planetary
diameters. With shorter distances, it's clear that the light rays
reaching the top and bottom of the planet are not parallel.
As regards the TV interlacing, it looks a bit harsh at the moment. I'd
suggest a bit of external post-processing (unless you consider such
things to be beneath you) to perform a slight vertical smoothing. It may
not be easy to find such a facility in an image post-processing program,
but if you have one that allows you to create your own image filters you
can set up one that looks like:-
0 1 0
0 4 0
0 1 0
[In Paintshop Pro 6 use Image:User_Defined_Filters and set up one with
that pattern in the centre and zeroes all round. Set the Division Factor
to 6 and the Bias to zero.]
The strength of the smoothing can be decreased by increasing the number
in the centre, (in Paintshop Pro, adjust the Division Factor to be the
sum of all the values).

Fabulous! Looks very much like a snapshot of a TV screen to me. I'm seeing
it here on a 19" monitor with .28 dp at 1600x1200 res. right now so it could
vary a lot on others knowing how lines change so much.
Real believeable anyhow, I love it. Thanks for showing it.

I've had a bit of a play with the TV interlacing code aswell,
I'm thinking of doing a shop full of TVs but having the
interlacing effect over the whole scene.
The space side of it looks good.

Same thing here, yes, it does look realistic.

The interlacing was done using a macro I created, based heavily on Glen's
code. I plan on sharing it once I get a couple fo things worked out to make
it more configurable. I've gotten some ideas from Glen on how I might go
about doing this, but I haven't had alot of time lately. This image has been
sitting on my hard drive for weeks before I got a chance to post it.
Hopefully it won't be weeks before I can post the macro.

Nope. Macro. I hope to be able to post it soon. When I do, I'll post a
message to thos thread.

Point taken, I'll have to fix that.

I don't have PSP6, or at least not yet. But for the most part I like to try
ot do thing completely within POV, not so much because I'm a purist as much
as because I like to see what I can do with it. Thanks just the same for the
suggestion. I may use it yet.
