LuxRender Windows CVS build of 25-08-2010

[Lord Crc]

Fresh new build! Ok not a lot changed, the two changes are that OpenGL support has been removed from the Qt GUI. This should help compatibility with intel graphics cards and such. Since we only use it for displaying/zooming, there shouldn't be a noticeable impact in performance.

Edit: Jeanphi pointed out something important that I had missed:

Scenes using rough materials (metal, roughglass, ...) should be reexported, the exponent computation has changed wih current development tree (it's approximately the square of the old value). The pool scene I often use for regression testing uses the metal material on the big sphere, and once the roughness is converted it works flawlessly, otherwise numerical inaccuracies when using too high exponents make it appear almost black.

The other nice news is that I've (hopefully) managed to do a SSE1 build of the Qt GUI. In order to cut down on my build directory I'm using the SSE1 build of Qt for both SSE1 and SSE2, again I don't think this should affect performance since we don't use any heavy functions in Qt.

Enjoy!

Added info from jeanphi about materials with roughness.

tnx Lord

Made a new build which hopefully should correct the Qt dependency for SSE1 (ie it should now work).

Still broken. Opened http://www.luxrender.net/mantis/view.php?id=833 in mantis.

When I try to run these I get a "side-by-side configuration error". Do these Windows development builds require the Microsoft VC++ 2008 runtime redistributable package to be installed?

I've done a fair bit of research to have them NOT require the redistributables. They do however require the dll's and the manifest file to be in the same directory.

Thanks.

I'm not sure which dlls and manifest files you are referring to?

I installed Visual Studio 2008 Express and all is welll now. I can run the VCS builds just fine. I hope I don't get as many fireflies with these new builds.

Since I have Visual Studio installed I just might as well try to compile LuxRender. I haven't coded C++ in a while but who knows, perhaps maybe soon I can contribute something back to the project!

The package (and directory with luxrender.exe) should contain

Code: Select all

msvcm90.dll
msvcp90.dll
msvcr90.dll
Microsoft.VC90.CRT.manifest

And the Qt dll's (QtCore4, QtGui4).
