LuxRender 0.8-dev Linux build of 12-12-2010

[SATtva]

Hello everybody,

This week we have a few fixes and a nice new addition. Jeanphi has fixed a regression in roughglass material which made it too dark. LordCrc's new experimental feature (outlier rejection dealing with fireflies) now works better in scenes with high intensity lightsources (like sun).

Jeanphi has also brought to us a great new toy -- a band texture similar to colorbands in Blender Internal Renderer. Read here for details (and here are some astonishing tests by neo2068).

Lux 0.8-dev branch (without OpenCL):
32-bit, SSE only
32-bit, SSE, SSE2
64-bit, SSE, SSE2
64-bit, SSE, SSE2, SSE3
(If you get "Illegal instruction" error when starting the program, make sure your CPU supports SSE instructions set this particular build was compiled for.)

Lux 0.8-dev branch (with OpenCL):
32-bit, SSE only
32-bit, SSE, SSE2
64-bit, SSE, SSE2
64-bit, SSE, SSE2, SSE3
(If you get "Illegal instruction" error when starting the program, make sure your CPU supports SSE instructions set this particular build was compiled for. If the program won't start because of libOpenCL missing, make sure you have ATI Stream SDK installed.)
(If you receive "/usr/lib/nvidia-current/libOpenCL.so: no version information available (required by ./luxrender)" warning, ignore it -- everything should work correctly nevertheless.)

Changes in LuxRender since the last weeklies included in these builds:

Code: Select all

18 hours ago    Asbjørn Heid    Added error output from ply loader. Made ply loader accept crlf line endings for header.
22 hours ago    Tom Bech    Added Thomas Ludwig (aka lyc/lycium) to authors list - better late than never I guess
2 days ago    Asbjørn Heid    Fixed access violation bug in infinitesample.
2 days ago    Jean-Philippe Grimaldi    Fix "band" texture parameters parsing.
3 days ago    Jean-Philippe Grimaldi    Fix a typo in photon map loading code.
4 days ago    Jean-Philippe Grimaldi    Small improvements to the band texture.
4 days ago    Jean-Philippe Grimaldi    Make sure roughglass roughness is within acceptable bounds.
4 days ago    Jean-Philippe Grimaldi    Fix roughglass (actually microfacet transmission) material after latest core changes.
5 days ago    Jean-Philippe Grimaldi    Add a new "band" texture to enable complex gradients.
5 days ago    dougal2    Added the actual decoder embedded_filedata
5 days ago    dougal2    Starting 'embedded_filedata' branch, with initial implementation embedded_filedata
6 days ago    Asbjørn Heid    Tweaked outlier rejection to improve results in high intensity scenes (ie sunsky).
8 days ago    David Bucciarelli    Fixed few GCC warnings


Changes in LuxBlend (for Blender 2.49b) since the last weeklies:

Code: Select all

4 hours ago    Jean-Philippe Grimaldi    Very basic band texture interface.
27 hours ago    Doug Hammond    Add string photonmaps file parameter to exphotonmap advanced settings.


[Oberon]

thx SATtva. Really appreciate your weeklys. Even more since I couldn't compile it by myself anymore.

[mib2berlin]

Same as Oberon, never get it to build by myself, and i tried often .

Thank you SATtva, cheers, mib

I wonder why OpenCL builds are 64-bit only?

[SATtva]

I have GCC constantly crashing on LuxRays compilation and virtually no spare time to figure out the problem. As nobody have much interest in those builds (judging by the lack of comments), I've just dropped them. I'll better invest my time (when I have some) in preparing my compilation scripts for the wider audience, so I don't have to make testing builds to fit even the most exotic environments.

[The Verb]

When do you think 0.8 will get a working SPPM intergrator?

[SATtva]

When Dade has some spare time to implement the missing parts, I guess.

[jeanphi]

Hi,

It's coming, Dade has just made another code drop to add the eye pass.

SATtva, we really need the 32-bit build! Please, one per month - is it real to do? I'm working with one, built in october
Thank you for your work!

[SATtva]

I've added 32-bit OpenCL builds. These are compiled with GCC 4.4.5.
