Thank you very much everyone !

Sorry for not replying earlier.
(I've been out in the real world doing a lot of ray-catching
with my macro lens today.)

I guess I'll use radiosity a lot in the future. I love it !


To Christoph:
I have now had a look at your radiosity pages and I find 
them very informative. Thanks for making them.

To Kari:
Can you give any clues on what differences we might see
if POV-Ray becomes able to output 48 bit images ?

To David:
I'm not familiar with "Rivenesque".
Do you have any links to nice Rivenesque images ?

Ahh... So it's about a game; Riven. Those images are great ! 
(I guess they are raytraced with radiosity =)

Is the game equally great ?


Thanks Andy.

I'm not sure which software they used on this.. maybe their own 'in-house'
code. I think they used Strata for Riven's predecessor.. 'Myst'.

You either love it or hate it, I think. Personally I really liked it.. very
atmospheric.. it's a puzzle-solving game really. My favourite aspect was
that although the game is mainly still images, occasionally parts of these
images are animated.. fireflies buzz around in dark caves etc.

You're welcome.

The game, pictures, music, and the mind behind them all is great.
So if someone calls your work "Rivenesque", take it for the 
compliment that it is.

Now you made me hope I that get the chance to try
these games one day.

Thanks, i'm already planning to add some new things, but don't know when i
have time to make them.

You have more possibilities to adjust contrast etc. after rendering
without too much loss of quality.  For example your picture whould still
contain enough diversity in the areas totally white in the 24 bit output.
Although most graphic output devices do not have those capabilities, this
would mean a much higher contrast ratio in the actual data.

What I don't understand is the problem itself, AFAIK Povray can generate
48 bit png files.

I plan to experiment with different post processing algorithms,
dynamic range compression etc., which take images with high dynamic
range and optimise them for monitor viewing. This requires the 48 bits.
The images should look more like photographs than CG. That's the short
version.

I haven't found a single program that can read those pngs and convert
them to raw or 48bit tiff for Photoshop and Matlab. Even some converter
program from the png group reported them as invalid.

But libpng obviously supports them (otherwise Povray could not write
them).  As the Delphi component i use for reading and writing png's works
fine with grayscale 16 bit i suppose it also works with 48 bit:

It should not be very difficult to write a conversion program, but it
would be better to directly write it with Povray, IIRC Povray 3.5 will add
tiff output.
