I thought it would be worth copying this up from the advanced camera discussions - I am now making QTVR's from 1 Lightwave image made with the advanced camera.

I have chosen the environment near Saturn for one of my first experiments. One above the rings and one below.

I'm quite pleased with it - though the stars are a a bit too big / bright. Star positions are accurate, but I have not tried to align the star field with Saturn's polar axis. Anyway, here are links to 2 scenes - you will need Quicktime installed to view them.

When I am sure I am doing this the best way, I plan to put together a tutorial on exactly how I did it, but the very short version is:

1) render an image in equirectangular panorama format, 360 wide by 180 high.
2) Put it through the free panocube software.
3) Watch in the Quicktime viewer!

Each file is less than 1 megabyte in size.

Feedback welcome - and suggestions or other good subjects!

Cheers,
Nick

That's pretty nice, especially for that size. I'm going to have to play with that.

Thanks Guys - I did make some changes from the defaults, Mainly in terms of the compression quality, where I set quality higher. Like I said when I am sure I know what I am up to, I will knock up a tutorial.

In the meantime is anyone wants the advanced camera preset, drop me a line.

Wow, I haven't played with the advanced camera much and those settings are rather intimidating. A tute for this technique is definitely a good idea.

OK, here are 2 more, one of my soviet style space station, one of the area near Jupiter and Europa.

I think part of the trick is to use a really big input image - the ones used for this were 4000x2000 pixels. Which if you think about it is only 500 pixels for a 45 degree field of view...

OK, the tutorial will take me a while, so here's something to get you started.

I've put the advanced camera preset on my downloads page:
http://www.starbase1.co.uk/downloads.htm

Set the image size to twice as wide as high, and go for a big image 2000x1000 minimum, 4000x2000 is better,

Keep the camera level - no pitch or roll. (It will work, but it will look ugly!)

Render it out, and feed the image into Panocube, (it's a simple drag and drop). Get the free version here:
http://www.panoshow.com/panocube.htm

(Panocube has instructions for downloading a free stitcher program it hooks into).

Panocube has a config file, I changed it for higher quality, less compression, and a bigger output image. It's not difficult.

Cheers,
Nick

Cool :D
The space station one is fun..
One question though, with the first two of saturn and it's rings .. is there two sets of shadows from the rings falling on the planet? It looks kinda strange..

Nope, the inner parts of the ring system are rather dark, (the ring data is very accurate here), and what you are seeing is the shadow of the rings on the planet THROUGH the ring system. Hence the crossed curves.

It can get a bit complex out there... Take a look at the real thing:
