Hi all,

It actually worked!, i have beed trying to do this for ages now, anyhow the
attached image montage shows the lense flare, view without lenses, overall
view of scene, and close up of 'camera box' with side cut away so you can
see the lenses.

Modeled totally in Moray, each image rendered 320x240 with RAD, the image
with the lense flare took about 5 mins to render.

This is really nice to see. I like the montage to show the overall
arrangement of lenses and the scene.
Am I right that you used the standart POVRAY and not UVPOV?

Really interesting.

I forgot to mention, if you put a light inside the camera box behind the
lenses it makes a cracking good spotlight - real bright :)

    Wow. Looks good. So how's it done ? (source ? description ?) What's RAD
?

yeah, this is really cool -- i think we should try to do more REAL stuff with
pov instead of just simulating it -- it'd b interesting to see how many
different flares can be done with this method instead of with actual "flare
shapes"

Awesome!  Could you _PLEASE_ post the Moray and POV sources?!

Wow! I thought it was uvpov!

And that brings me to my point: With uvpov it would be better! POV cannot
handle caustics and real reflection very well, so the lens flare would
actually be more correct using uvpov, I think.

And one quiestion:
What kind of camera type did you use? It should be an isometric one (with
parallell rays) behind the lenses, because your camera really is in front of
the camera. You did not mention this, so I assume you have used the standard
pin-hole camera.

By all means! A great effort. Are there any docs on lenses and cameras
around the net?

Oh, one more thing: Why not use the dispersion patch. Using that, one should
even be able to simulate focal blur and such. Whee... Try it, TYRY IT!

Thanks for a great image!

I will sort out some source code to post at some point, but i am not totally
happy with it all yet..

I want to model a decent set of lenses before i go uvpov, however it will be
better.

Yes standard pov camera, and iso cam would be much better, but untill i have
sort out a better set of lenses and virtual camera assembly it may not may
much difference

No, i have search for hours - i am off to the local library today to find
some books with detailed real world lense sets in - but i dont fancy my
chances

Knock around here for a while. I has several images of real world
mirror, optics, and lens assemblies:
