Stereo 3D Users: I tested out the Samsung Syncmaster 2233RZ / NVIDIA 3D Vision bundle today ($599 for a 120 Hz LCD display with one pair of glasses). Unfortunately, the 2233RZ display is clearly not yet a drop-in replacement for your stereo-3D-capable CRT: The display is very nice, and the stereo quality is excellent (as good as a CRT!), but only provided that you: 1. Run Microsoft Vista. 2. Install a high-end GeForce 3D card (9800 GT or similar). 3. Have DirectX-based software than has been modified to support nVidia's "consumer-grade" stereo API. 4. Use nVidia's 3D Vision glasses and sync emitter (a USB-based device). In other words, despite the high stereo image quality, this is not yet a servicable stereo 3D solution for professional use. Rats! I was very much hoping that this new display would nevertheless also work with existing nVidia Quadro-based Mac or Linux systems with existing emitters and glasses running existing OpenGL software. Sadly, this does not seem to be the case due at least in part to the fact that the phase of the sync signal coming out of the Quadro card does not match the update phase of the LCD display. In addition, light from the display itself seems to corrupt the sync signal for StereoGraphics glasses. So, in summary, it seems we are out of luck until nVidia does a bit more work. Reportedly, there is a driver update coming that will target use of nVidia's 3D vision glasses with Quadro-based graphics cards, so stay tuned. Cheers, Warren |

Just in case anyone wants to track this, here is the source I found of that report: "Quad Buffered Stereo will be supported with the NVIDIA GeForce 3D vision glasses in upcoming driver release by spring 2009." <http://www.nvidia.com/object/quadro_stereo_technology.html> -- Thanks, Donnie Donnie Berkholz Developer, Gentoo Linux Blog: http://dberkholz.wordpress.com |

I am particularly curious whether this works on Linux, or whether it needs some sort of USB driver stubs so that Linux knows what to do with these devices. It comes with a stereo-DIN cable so it seems like it could work, provided the emitter can get power via USB and the glasses can charge via USB. If the new glasses can work with a CRT, then at least we could buy stereo bundles now and use all of the parts of them in some sort of Frankenstein setup pending support for LCD stereo. -- Thanks, Donnie Donnie Berkholz Developer, Gentoo Linux Blog: http://dberkholz.wordpress.com |

I have three questions I'm hoping someone can help with. 1. Does anyone have, or can anyone point me to a program that will generate a nice pdb file that contains 50 or so base pairs of random sequence B form DNA with hydrogen bonds between the bases or no H bonds? I need to be able to scultp the DNA and have one strand react to the pulling of the other strand. I also want to show the union of the AT and GC via H bonds. The H bonds can be regular bonds (and probably will have to be if I'm going to be sculpting). I can make the h bonds and make them real bonds for the sculpting, I'm just wondering of anyone has already done it or has a script around.... 2. When showing a cartoon of DNA the ribose ring in the backbone is always there no matter which setting you choose. How can I make the phosphates and the ribose rings show as a backbone cartoon "tube" and keep just the bases as filled sticks with rinngs? 3. Rings on DNA and RNA can be filled, in cartoon mode. But I can't get the rings to fill in on selected amino acids (H, W, Y, F) in a protein of that same file. Is there a fill amino acid ring setting? Thanks in advance for anything you can offer, Adam -- _______________________________________ H.

Hello You can look into 3DNA out of Rutgers (http://rutchem.rutgers.edu/~xiangjun/3DNA/). To make the image you describe you will also need to use Raster3D. 3DNA has some basic scripts for this but you will need to write your own to get the image you describe.
