Hi,
I'm Daniel Ngu from New Zealand. I'm a new user of POVRay and I'm a huge
fan. It opened up new doors for me and let me in to a whole new universe.
I just spent these couple of days going through the tutorials in the help
menu, trying to learn to use POVRay and its language. I'm also checking
out other free raytracing programs out there, one that I'm also very
interested in is Virtualight. Since I'm a new comer, would you please let
me know if you had tried out Virtualight as well and what you think of it
and how it differs from POVRay. This is not meant to be critical, just
educational and from analytical standpoint.
I have been going through the Virtualight's manual, one note I'll like to
make is how similar its language is to POVRay. I could interchange the
source file between the two renderer pretty well. However, there are times
that I found Virtualight do provide features that are more readily
available,
such as the use of sunlight as a light source. How do I achieve the same
effect in POVRay?
Daniel.

Since I never played with VirtuaLight I can say only from my point of view which
is POV focused:
- I do not see link to sources on VirtualLight homepage
- I do not see binaries for other platforms on their site
- I know that some of their planned features are already available in POV as
patches (HDRI, support for shader scripts, motion blur, post-processing) since
times of POV 3.1 and earlier
- looking at the gallery I do not see any image which coould be not faked with
POV-Ray by some of the POV artists I know
- it wasn't used in Soyuz ;-)
But I'm sure there are reasons why this tool has three different forums and so
pretty fast development. That's good there is an alternative to raytracing.

Hello and welcome,
i have never tried Virtualight myself but from the features description it
does not supply any features that are not available in POV-Ray (unless you
count scanline rendering abilities) while there are a lot of advantages of
POV-Ray on the other hand, for example:
- free usage even for commencial purposes
- availability of source code
- availability for non-Windows platforms
- powerful scene description language
- suitability for large scenes (i have not seen any complicatred scene
made with virtualight until now)

Do you have a link to this product? I could only find a web-design company
by this name. Ta.

It almost looks like the authors tried to implement everything that is useful
in POV-Ray. I wonder what their source code looks like...

Thanks everyone for your views, all of which are good and solid reasonings.
BTW, is there a good repository to get photorealistic povray files to test
out?
Daniel.

I'm not really sure what kind of repository you are looking for but perhaps this
link can give you some applicable set of url:

The main sources for Pov-Ray scene files (photorealistic or not) are:
- the "advanced" directory of the official Pov-Ray distribution
- the two "scene-files" (text and binaries) groups in this forum
- the www.irtc.org site (many Pov-Ray images are given with a more or less
functional scene code)
Users' sites often contain full scenes :
Jaime Vives Piqueres' http://www.ignorancia.org/galleries.php
My own site : http://www.oyonale.com/ressources/english/ (scroll down to
"macros and sources")
See also a (far from exhaustive, still in the process to be completed) list
of such sites here:

Welcome Daniel.
I have not tried Virtual Light, but POV-Ray is an extensive language with 11
years background. Many people have contributed to POV-Ray over the years. It
has a large fan-base.

Some features may be readily available in Virtual Light, but when you get to
know POV-Ray, there are a lot of "plugins" that I think it will turn around
the picture for you. They are usually called "include files" or "macros".
Regarding your sunlight question, I'll need a bit more information before
I'm sure what you're after. But if you want to use "real" objects or skies
as light sources, try radiosity (for diffuse reflections) and the
"reflection" keyword on objects where you want specular reflection from the
sun.
Regards,
Hugo
