LuxRender v0.1 Release Candidate 3 available

[ckbrd]

Hi Radiance

Do you have an idea when you would have
shaders for fabric/velvet and SSS/silicon
in LuxRender?

Hy, sorry for delay..
Here you can find pkg that install luxrender gui application and luxconsole
http://www.simplyjust.it/lux/LuxRender0.1RC3.zip
and here for only gui application

Just got back from the land of no internets, and glad to see the OS X version is here! I'll get to testing it right away.

Slight snag on that testing - Both the pkg and the GUI-only app copy/install fine, but the application does not open. No error message or anything, just nothing happens.

Macbook Pro, Intel dual-core, OS X 10.4.

Still having problems (although something has changed) with the old cornell scene here.
CVS version on linux Debian Etch, compiled with icc, latest luxblend, intel core2 duo, MLT, random sampler.

Hi, I've just committed a patch for correct sampling of complex, non-planar area-lights.
Here's how that cornell scene is being rendered now:

radiance the metal shaders, are those measured NK datas, or self created?

I'm the author of the original metal material. The data comes from measurements found in the public domain. The original data was sampled at discrete wavelengths, so they had to be integrated using the CIE RGB color matching functions (since pbrt just happens to use RGB internally). I've planned on making the material perform the integration at creation time, so that one could use other measurements more easily and so that it naturally supports sampling at more than 3 wavelengths.

As for the RC3, there seems to be a few issues. Since I'm quite new here I don't know if these are known:

- Using MTL generates "weird" exr files. Looks almost like a LDR image, except very washed out and bland. Tonemapped LDR images look good tho, which is weird imho.
- Renderer fails to write out image when finished.
- There seems to be a normalization issue with progressive rendering. HDR output gets VERY bright if left alone for a long time. I'll try to narrow this one down a bit, find a good test scene etc.

I have the same problem. I have tested it on two PPC Macs so far (both 10.4) and it installed, but it didn't open.
I will test it on an intel mac soon as well.

- There seems to be a normalization issue with progressive rendering. HDR output gets VERY bright if left alone for a long time. I'll try to narrow this one down a bit, find a good test scene etc.

Well, it's not the progressive part, nor the MultiImage, it has to do with samples per pixel. Above a certain amount, artifacts starts to appear. Are NaN samples handled differently in Lux compared to pbrt? How about infitine samples? Because I consistently get a few NaN samples in pbrt when using a high sample/pixel count.

I've upped a test scene here: http://www.dump.no/files/673a3053d3b8/testscene.zip
It uses the cropping window so that the rendering should only take a few secs, even at high samples/pixel count.

Here's what it looks like on my machine.

Hi radiance
I get that diagonal line bug. I wont post a pic as it happens on everything i render. (let me know if you want one anyway)

2GB 800MHz DDR2 RAM

Q6600 Intel Core2Due Quad core 2.4GHz

ASUS P5K-SE (no overclocking of any kind)

PALIT 8600GTS 1GB GDDR3

For all the people with problems on MAC OS X,
The forum member who made the package (neo1975)
is currently moving houses with no internet connection,
so don't expect him to provide help anytime soon.

unfortunateley no other developers have access to a Mac OS X machine currently,
so if anyone with a Mac and some Unix knowledge would like to see what the problem is,
please be my guest

Thnx!,
radiance
