New examples of LuxRender features in Wiki

[Daniel Scott Matthews]

Tim has been churning out features for LuxRenderer, we now have a full
Sun and Sky system with accurate positioning! New materials Metal and
Glass. But most impressive is the EXR based Environment Lighting.

http://www.k-3d.org/wiki/User:Dsmatthews/LuxRender/materials/Lux_Metal


Given LuxRender works so well on a network, I'd like to see what can
be done by somebody with access to a corporate or university network.
You should now be able accurately animate the sunlight and shading of
an architectural model throughout the day, or the months of the year.
Adding all your frames together will give you a HDR accumulated
isolation map which is also useful for landscaping near structures.

At the moment I have only got access to a max of 8 CPU cores, so I'd
like to hear from anyone else who can help with testing and example
image/animation production.

In the mean time my daughter and I are off to the train museum for
some industrial inspiration, and the circus train activities. :-)

Looks great! One minor gripe: it seems the normals on the objects are
per-face normals, where per-vertex normals would look smoother. Are
the normals calculated by Lux, or are they passed on by K-3D?

The LuxRender output is far from complete, but it did not even exist a
week ago so I'm very impressed with the progress.

Here are the specs:

I just realized that this is in XML, not standard LuxRender format,
sorry about that.

We aren't passing normals to LuxRender yet.

They are now, Tim has added the required modules.

Thanks Tim, the adipose endowed fellow is now looking more normal,

As a tiny suggestion: you could prepare something for the front page.
The magician girl probably has the right hand a bit tired. :-D

LOL, yes, but we still don't have UV mapping sorted out for meshes,
perhaps when the toolset is a little more complete we can collaborate
on a few demonstration images.

Daniel, could you record some video tutorial showing how you made that
image or something similar with Luxrender?
Right now I am not able to make more K-3D tutorials and I would like to
upload something to the K-3D youtube channel.

Cheers!

There is no Luxrender functionality in any of the built releases, only
in the code repositories, perhaps it is better to wait until the next
release, which hopefully will be more complete and have some level of
UV assignment, if not complete editing. Then people will not get
disappointed when they find they can't emulate the technique in the
video's without learning how to build the application from source
code.

Tim, Bart: let me know about a week before the next release and I will
do a few video demos, actually let me know a month before so we can
test everything and iron out and app crashing bugs first.

No rush, I'd just like to know, when you know, so I can do my bit.

In the mean time, behold the stealth cow!
