Hi!

I was playing with sponza atrium recently.
Each picture was rendered with megapov 1.1 in about 2 hours.
They were not post processed.
I though it is worth sharing...

Regards,

Jerome

Beautifull!
Very nice modelling and textures. I can hardly guess what is a modelled
detail and what is an image mapped texture.
The only thing which is is not perfect is depth of field effect, which has
too much noise for me.
By the way - has anybody tried to make an post-processed DOF with MegaPov
new features? I mean to create depth map first and then to use it for
blurring original image?

Awesome!
*gathers jaw from floor*

Is the source available somewhere? (A quick google showed that this seems to
be a model used to compare lighting algorithms)

Hum... thanks but... :-)
See : http://hdri.cgtechniques.com/~sponza/
the Atrium was modelled and textured by Marko Dabrovic.

The picture is noisy indeed but it is just a preliminary work.

Beautiful! What is "Sponza Atrium"? Google to the rescue!

Przemek,

The attached image was made using POV-Ray 3.6 and the Gimp (image 
editor). Three files were used to make it: one to make a depth_map of 
the geometry, one to render the sharp image, and one to put the first 
two images together to make the fake depth-of-field effect.

The effect is far from perfect. I had to blur the depth map with the 
Gimp so that the edges wouldn't remain sharp.

I can post the files with basic instructions if you are interested.

-Sam

Beautiful!

Btw, how about (all of us) posting own images with a small banner 
containing

1) PovRAY 3.6 bleh,bleh..
2) (C) 2004 by...
3) WWW page

this way we can promote PovRAY, and also ourselfs :)

Cool, but why to promote it with wrong shape of the name?

Whell... even the WWW should be change btw ;)


Oh, I see it is (redirection to povray).

Hi Sam!
Yes, this is what I was asking for. I've managed to make a similliar effect
with the Gimp. Upper two are the original images rendered with MegaPov,
lower left is the final image with faked DOF, and lower right is depth-map
corrected by making difference with gray, to shift focal point to the
middle.
My only question to you is about applying blur: Is there any way to apply an
effect selectively relative to gray map? In my image I've made layer mask
and then converted it to selection - Is it the right way?

Still I am investigating possibility of making this effect directly in
MegaPov in a similar way like "convolution_matrix" macro works, but with
creating new matrix for each point. It will be probably very slow, but
maybe faster then original DOF procedure.

Greetings!
Przemek
