Testing OpenCL path tracing with SmallptGPU & SmallLuxGPU (to become LuxRenderGPU)

#24

Installing the Blender plug-in is very simple, you just extract the plug-in into the scripts/io directory. The more difficult part is making sure you have working OpenCL and compatible display drivers installed properly for your graphics cards and are able to run David’s SmallLuxGPU demo directly. Right now, if you are not technical at all, then it may not be appropriate for you just yet; this is a test phase, OpenCL is in it’s early days, and this is not yet a one-click install solution.

Edit: classroom test render with previous version:

By the way, David is adding blurred reflections / metal material to his test program, and it appears to come without a cost to render times! See below example renders made with SmallLuxGPU v1.4beta2 dev. preview:

OK many thanks , i will try to od it :).

Good blendering then hehehee

David has put up a video showing SmallLuxGPU v1.4 in interactive “low latency” mode on a PC with one GPU as well as a couple of short batch renders done on a PC with two GPUs. Scenes were all prepared with and exported from Blender.

This will give you a good idea of the performance of SmallLuxGPU in interactive mode.

Keep in mind that these scenes are all high poly scenes (from 100K to 1M polygons).

Note that this is all brute force path tracing rendering! (it’s a little crazy)

see the video: SmallLuxGPU v1.4 (OpenCL) (Vimeo)

FYI David has released v1.4beta2 of SmallLuxGPU with several new features, including metal/blurred reflections support and texture mapping as well. See Luxrender forums, GPU acceleration (member’s) section.
A new version of my Blender 2.5 plug-in is also available to match…

David continues progress on SmallLuxGPUv1.4, coming up for beta3: HDR lighting and camera depth of field (as well as other features such as saving render results in OpenEXR format). Some SmallLuxGPU render samples:

Sweet! these are great looking results so far, keep up the good work on this. :slight_smile:

Is the render engine can be used on other 3d program (I use 3ds max) or is it just for blender only?

#31

Looking very nice.

#32

I’s an external engine not specific to blender,
so yeah, it should work with max too,
but I’m unsure if theres a working exporter yet.

#33

Hi, a max exporter is available at luxrender forum.
You have to signed in to read this part of the forum.

SmallLuxGPU has been advancing significantly. It’s now at version 1.5beta3, and boasts many new features.

I’ve created a short animation using Blender 2.5 and rendered with SmallLuxGPU v1.5:

For more information (and demonstration videos) goto: SmallLuxGPU (SLG) wiki page

#35

LOOKS GOOD , excuse me

How long does the animation take ?.

Yoy know i’m gonna use luxrender for my animation :stuck_out_tongue: .

#36

You mean to render? Varied from 10 to 30 seconds per frame, depending on complexity of the frame, I’m guessing average was around 20 seconds per frame.

edit: note that with SmallLuxGPU you can render (and navigate it) in real-time, but to get a clean rendered image without grain, you want to let it cook a little, which is what I did. For the animation I simply requested SLG to render a mimimum number of samples per frame (I picked a number).

#37

Oh that really fast :).

 THANKS for the information  my friend
#38

Looks great Sphere, in what GPU did you rendered it? the CPU was also in calculations?

#39

I have ATI 4890 and yes CPU is an i7 920.

BTW…

Here’s Another animation showing off SmallLuxGPU’s new camera motion blur and sun and sky features. Fixed 20 seconds per frame render time, over 1.75 million triangles in scene:

Another quick SmallLuxGPU test animation with camera depth of field, motion blur, textures, HDRI lighting (20 seconds per frame render time):

#41

One more silly animation rendered using SmallLuxGPU v1.5… (100 samples per pixel, 14 to 48 seconds per (HD!) frame. HDRI lighting with camera depth of field.

i Sphere♥ looks really good your videos :P.

But you can make a vimeo tutorial how to use SmallLuxGPU .

I hope you can do it :wink:

#43

OpenCL (multi CPU+GPU) accelerated SmallLuxGPU (SLG) / LuxRays testbed renderer progress continues… faster Path tracing and new features including: SPPM rendering, real-time editing of rendering scenes from inside Blender, instancing, etc. and David Bucciarelli is now in the process of implementing even faster OpenCL rendering kernel on the GPU (reached 157 Megarays/sec.).

Check out a neat new video showing off some of the real-time editing features of SmallLuxGPU rendering scenes using Blender 2.5 (as well as instancing):
