Arch + Blender + SmallLuxGPU

Just something I have been messing with in Blender 2.5 Beta. Rendered on SmallLuxGPU using stochastic progressive photon mapping entirely on the GPU (OpenCL).

English please ...
And can I have one in blue? Would that mean you have to re-render everything?

mrunion · 2010-07-28 13:32:01

Looks good! I can't wait to play with that stuff myself!

Labello · 2010-07-28 14:43:37

wtf!?

how did u get this working? :-(

i was not able to compile SmallLuxGPU on my installation... could you please point out which packages are needed? i got nvidia here :-)

btw: it is not computed on GPU entirely since i think it just uses the GPU for interesection-calculus :-)

It's a new algorithm for tracing light moving through and around a scene. Works extremely well with caustics (glass) and is much faster than using something like Path Tracing. I am really just learning about all the different algorithms myself.

And yes, it would mean I would have to re-render it, which is about 10 hours to get to wallpaper size. Maybe another day, but I don't really feel like eating up my cycles with another version now.

The only package that I needed above what Blender needed (I compile that from the SVN every night) was opencl. It looks for the OpenCL library (libOpenCL.so), which I am pretty sure I got from the AUR. The package is called opencl-headers.

I don't know about the intersection-calculus, Dade is the person to ask that over on the Luxrender forums.

Yeah, I JUST saw your post in the topic over there. lol.

I tried to make my first PKGBUILD!

could anyone please verify that this works? i do not know what to enter in source=() since the source is fetched from the server. this is somehow confusing to me :-(

this PKGBUILD is based upon the luxrender-hg PGKBUILD

pkgname=luxrays-hg
pkgver=2356
pkgrel=1
pkgdesc="Rendering system for physically correct, unbiased image synthesis using your graphics card"
arch=('i686' 'x86_64')
url="http://www.luxrender.net/"
license=('GPL')
depends=('libgl' 'boost-libs' 'freeimage' 'freeglut' 'opencl-headers')
makedepends=('mercurial' 'cmake' 'boost')
source=(??)


_hgroot="http://src.luxrender.net"
_hgrepo="luxrays"

build() {
  cd "$srcdir"
  msg "Connecting to $_hgrepo Mercurial server......."
  if [ -d $_hgrepo ]; then
    cd "$srcdir"/$_hgrepo
    hg pull -u
    cd "$srcdir"
  else
    hg clone -b default $_hgroot/$_hgrepo $_hgrepo || return 1
  fi  

  msg "Mercurial checkout done or server timeout"
  msg "Starting make..."

  if [ -e "$srcdir"/$_hgrepo-build ]; then
    rm -rf "$srcdir"/$_hgrepo-build
  fi
  cp -r "$srcdir"/lux "$srcdir"/$_hgrepo-build
  cd "$srcdir"/$_hgrepo-build  

  cmake -DCMAKE_INSTALL_PREFIX=/usr .
  make || return 1
}

package() {
  cd "$srcdir"/$_hgrepo-build
  make DESTDIR="$pkgdir" install

  # fix library path on x86_64
  [ "$CARCH" = "x86_64" ] && mv "$pkgdir"/usr/lib64 "$pkgdir"/usr/lib 
}

How did you get SLG to work on Arch? I tried the binary distribution, but it fails because the boost libs are new.

Dade uses Ubuntu, so yeah, you can't use the binary distribution that he releases. I download the source from the server and compile it myself with cmake. Really easy to do.

Labello · 2010-08-25 16:01:26

a PKGBUILD would be cool. :-) i tried but did anyone test it? :3

May you be persuaded to give us a walk-through on building SLG? Pretty please.

Labello · 2010-08-25 19:37:56

well it is quite straightforward. there is a wikipage on the luxrender site that outlines the dependencies and build process:
http://www.luxrender.net/wiki/index.php … g_on_Linux

foxbunny · 2010-08-25 20:15:43

Thanks for that. I missed that page.

I have subscribed to this post when it got posted, it's not because I use Blender but because I was waiting for someone to ask this question "What's that object in the image?" (I would feel shamed if I ask that question)

But no one has asked that question, I guess I am the only one who couldn't figure out what that object is. So, please kindly tell me what's that object in the image?

foxbunny · 2010-08-25 23:21:08

Hehe, I was actually wondering the same, but the fact that SLG works on Arch was priority.

lifeafter2am · 2010-08-25 23:39:18

It's just a glass abstract sculpture. I mainly made it to test out using the new SPPM rendering since it handles caustics so well.

Ah.. now I see, a sculpture. It's art!

cesura · 2010-08-26 00:36:10

Nice work!

Note: This is why I program. I'm not much of an artist.

goplexian · 2010-09-04 09:10:47

I just thought I'd mention that there is now a package build for SmallLuxGPU for Blender-2.5

Actually SmallLuxGPU was just a demo project, the real name is Luxrays. So the package is called Luxrays, not SmallLuxGPU.

The package can be found on Aur of course.

And I just explained how to get started over on my blog if you are interested.

this rocks so hard! thanks man!

i am wondering whether you added nvidia-utils as dependency? ati afaik does also support luxray. i know that most devs of luxrender use ati. so this should work too.

did anyone test this package with ati? :-) /me hat nvidia too.
