Blender Adds Raytracing
rastachops writes "Blender, the Open Source 3D modelling tool has recently added Raytracing to its extensive list of features. 'Believe it or not, but Ton has integrated the raytracer from Blender's predecessor, Traces into Blender. He said "the algorithm has been optimized and is now ten times faster. Combine that with a PC that's forty times faster than in the early 1990's and raytracing is almost usable". For a comparison checkout the before and after screenshots.'"
Your raytracing example appears to be using a point light source and not modelling any atmospheric effects, so naturally it looks rather basic. If you use a proper extended light source and set up your raytracer to model the atmosphere properly then it will look much better. If your raytracing program can't do that it's a limitation of that particular program, not raytracing in general. /lot/ more CPU time...
Of course, proper accurate raytracing as I've described will take a

As a blender user and foundation member I've watched as the features, inovations, and rate of development have gone up since it went open source and GPL last year. We have tons of new python scripts, a new gui that continues to evolve, better rendering...
It's not Maya, but it's on par with anything in the low-mid range for windows, and it's getting better by leaps and bounds
Give Blender a couple years and we might Hollywood contributing code. Hollywood lves Gimp, and I could see this becoming a real player in 3D.
What an odd comment. Even in the relatively early days (I personally started with rev 1.76) Blender has always rendered faster under Linux than Windows. Editing performance was a bit of a problem, since most gfx cards did not support Hardware acceleration under linux. (DRI was a fairly new addition to XFree86 at that time.) Blender is rather 3D graffics hardware intensive (are any 3D apps not?) as it was born under Irix on SGI boxes. However, things have changed. Two of the major vendors of high-end 3D gfx cards now have very good accelerated support either through their own driver (NVidia) or the DRI module (ATI). With the former, performance between Windows and Linux is nearly identical. For ATI users Linux performance can often be better, due to the fact that ATI's Windows drivers are much more painful to configure than DRl (you probably could get better performance from Window's drivers if you spent many many hours tweaking the ATI driver settings). Those two brands of card probably cover 95% of all serious 3D users. Blender is ment to be a proffessional application, not a toy. It has a way to go to be on par with Maya or LW, but even now, as an 80% ready application at 0% cost, it is an excelent tool for beginers, and even many professionals who don't regularly need many of the advanced (and expensive) features of the high end packages. I'll even risk being /.'s http://www.soylent-green.com to see some of my blender work. And I'm not even a power user.

If you guys like blender, you might be interested in another project called Art of Illusion. It is a poly-based modeller and renderer and I have seen some amazing results. It's completely open source (GPL I think) and achieves great performance being written completely in Java. Check it out, and also the other work Nate has done.
