LuxRender Linux CVS build of 09-11-2009

[SATtva]

Hi guys!

In order to return back to the schedule of Sunday posts I'll provide this semi-weekly batch of builds. :) Though only five days have passed since the last "weekly builds", this one is definitely not feature-free. First, these builds include the new experimental Qt GUI for LuxRender, see the luxrenderqt executable in the archives. My tests has shown it to be very promising, but it would be better for you to try it yourself and share your thoughts and findings. By the way, Qt libs were linked dynamically with the luxrenderqt binary, so make sure your system has Qt-Core, Qt-GUI, and Qt-OpenGL libraries installed. I've used version 4.5.3, but I think any 4.5.x would suffice.

Second, Dade has introduced the new Dynamic Epsilon feature which aims to get rid of self-shadowing artifacts on very large models. Try it out. Third, Lord Crc has fixed a couple of bugs in TGA and alpha channel outputs. Last, but not least, Tomb updated the LuxBlend script in terms of infinitesample environment support and exphotonmap integrator advanced options support (see this thread to find out their meaning) as well as applied the patch for proper particles export. Of course, there was many other improvements and fixes, see the changelog below for a full list.

Be aware that these builds aren't betas nor alphas. These are just testing builds of the latest development snapshot for people to play with and report their early results and findings. Please don't expect these builds to be bug-free, but don't hesitate to report about something you think is wrong.

Here are archives with all Lux tools built for corresponding platforms and CPU SIMD instructions. Grab the one most suitable for your hardware. 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 you think there should be additional builds for other SIMD sets, just let me know. I can't afford to build every possible combination, but will expand the list if there is enough interest in a particular set.)

Thanks a lot SATva, you're a lean mean building machine

[SATtva]

Haha :D
Now it takes only half an hour to compile everything, so, hey, not a problem really! ;)

[psor]

Awesome, thank you!

If you've some spare time left it would be very nice if you could write about how to setup such a system to build all the stuff.
Maybe you could use the wiki for it. I think a lot of people would find this very useful too. This has no priority but as I said,
maybe when you've some spare time. I would appreciate it a lot. ;o))



take care

Okay, thanks for the idea. The methodology mostly comes from jromang's Linux static building guide, just adopted for GCC and consolidated in a number of ad hoc scripts making all the process (aside from patching CMakeLists.txt) fully automatic. I will publish the scripts themselves and instructions on how to use them.

Thanks for the build!
This one seems to work (the one from 4th novmeber was damn slow, there must have been a problem with it). THere is just one thing, and that is transparency. I keep on reading that these new builds are solving alpha-issues, but the opposite seems to be the case, at least for me.
I need to have planes with just a logo on it, the rest to be transparent. With 0.6 this is not a problem (at least with mlt/bidir), however with every recent build i tried (both on linux and OSX) the transparency is NOT fully transparent but has a dark color, with a transparency of, i would say, 80%). I noticed that in both, the render and the material-preview in luxblend. I tried with MLT/BiDir and other integrators.
Any idea on that?

Cheers!

Sebastian

Hi,

Please report issues in the Mantis bug tracker otherwise they could be forgotten. Regressions should be set with a high priority.

Hi sebastian_k,

I keep on reading that these new builds are solving alpha-issues, but the opposite seems to be the case, at least for me.

If you're referring to the problem you have reported here, then this is unrelated to the alpha-channel problem Lord Crc has solved. That resolved problem was related to the alpha-channel of the output image in RGBA format. See here for more details. But your particular problem is related to the null material transparency, so it's something new.

Jeanphi, I'm getting the following error with bidir+infinitesample combo:

Severe error: 14] Unimplemented Light::Sample_L

With path tracing infinitesample works correctly. If this is a known issue, I'd prefer not to clutter Mantis. :) Otherwise I can create a task.

Jeanphi, I'm getting the following error with bidir+infinitesample combo:

Severe error: 14] Unimplemented Light::Sample_L

With path tracing infinitesample works correctly. If this is a known issue, I'd prefer not to clutter Mantis. Otherwise I can create a task.

My first idea was of a method left out of the dynamic epsilon patch but it looks like infinitesample is really missing the implementation on one Sample_L method
