Re: interesting announcement - autodesk to buy SoftImage..

There are still Rhino and Cinema4D left. Rhino is dirt cheap and Cinema4D known for very good work flow. Since Cinema4D from Maxon belongs to Nemetschek ( a player in the CAD market too)I guess here will be no possibility to buy that one.

Re: Through the Looking Glass

Did you implement adaptive sampling ? Doesn't make sense to sample on materials that don't need it. Maxwell really takes a lot time to render and you often still see noise in the final image. What is pretty nice with maxwell is that you can reposition the lights after the calculation so it is pretty...

Re: Through the Looking Glass

Great work Squeen. What have you done in the meantime feature- or performance wise ? We have finally implemented clustering with load balancing and this is real nice thing. Next steps is to get ahold of a nehalem system. One of our customers has access to preproduction hardware and reported a speed ...

Re: Through the Looking Glass

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOHOOOOOOOOOOOOOOOOOO :shock: :shock: :shock: :shock: :shock: I'd like to use so many cores really, but we are also working on finding bottlenecks. Our small tracer currently trains to run on 8 machines with 8 cores to drive a full hd display (1920x1080). At the moment we ...

Re: Through the Looking Glass

Very interesting. Can you give me the raw render time (without loading file and building the kd-tree) ? Typically it should be better to build blocks instead of scanlines, because neighbouring rays touch nearly equal segments of memory. Of course this is only valid for primary rays ... remember prim...

Re: Through the Looking Glass

The image looks real great. What do you think is your biggest bottleneck ? What kind of network topology are you using ? We have found out that standard gigabit ethernet on the master does not make much sense anymore when you are passing a certain number of slaves (thus reaching a certain speed). Yo...

Re: when ray-tracing will be done in real time ?

Well a very interesting topic. It all depends on what you want to achieve with raytracing. Do you only want some nice reflections and refractions then there are already some solutions (we are doing that already). But the raytracing algorithm automaticaly tends to implement more features that increas...

@Squeen

Are you still alive or been sucked away by the fan arrays of your cluster :lol:

Re: Through the Looking Glass

I'm kinda excited because I may be able to run our little ray tracer on a 2500 core cluster next week. Hope you have enough time to work on the efficiency. We are currently implementing computation clustering as well and there are all kind of strange things to be aware of (bandwidth issues, latency...

Re: Learning OpenGL

Take the O2 (and put some more ram and maybe a 300mhz r5k processor inside) and use NeHe's OpenGL Tutorials ( http://nehe.gamedev.net/ )

Good luck and enjoy the journey

Re: Through the Looking Glass

You've probably heard the saying if it looks like computer graphics, then it's bad computer graphics. Well those shots definitely don't look like computer graphics. In particular, I like the top of the car in the black & white airport image---how the glare from the window shield and roof merge ...

Re: Through the Looking Glass

Thanx for the compliments. There are still things to tweak like minor bugs within the model itself and still hundreds of features to implement, but its really a rocking trip with something happening everyday. The next image will be one from a real photographic artist. He made me speechless last week...

Re: Through the Looking Glass

OK, I shouldn't have used PNG files, have replaced them with smaller jpegs (smaller than those rescaled png files), so nobody is hurt ;)

Re: Through the Looking Glass

naa not these days but I promise more images as soon as we are allowed to. In the meantime we had to return back the 32core machine. Really a nice screamer (did I say LOUD ?). We got some 6-8 fps on 1megapixel resolutions, scaling efficiency was around 85% (getting a 27 times speedup compared to a s...
