Matt covered pretty much everything, but note that for active glasses plus a 120Hz LCD (number 2 below), you'll want a Quadro card instead of a Geforce card; Chimera works in windowed mode with Nvidia 3D vision and a Quadro card. The advantage over the crystal eyes setup is that because Nvidia 3D vision uses a usb-connected emitter, the Quadro card need not be equipped with an onboard stereo port, so you can buy a cheap ($120) model like the FX380. <br>
<br>I also have a setup that uses a cheaper projector capable of 85Hz sequential projection, a FX4500 Quadro card I bought used for $500, and 30pr of relatively cheap active eyewear (the $100 edimensional glasses). But honestly, active eyewear is a bad idea for large audiences. Bad. I covet Matt's passive setup with the infocus projector. <br>

<br>
It turns out it is a complicated answer depending on various factors. I will outline some of the issues.<br>
<br>
If you are doing a workstation only, that is not supporting a projector for a lot of users, the cheapest route is row interleave; zalman makes a display for $300, and uses cheap glasses ($1-$15) the same used in most movie theaters; no additional hardware. The downside is you loose half your vertical resolution.<br>
<br>
If you are doing a workstation only and want maximum vertical resolution you will need to go with active glasses.<br>
There are several ways to make this happen:<br>
1) crystal eyes glasses ($300), quadro card ($1800), emitter ($100), CRT ($200-500); <a href="http://stereographics.com" target="_blank">stereographics.com</a>. NuVision offers cheaper glasses. Someday someone might offer a 120HZ compatible LCD display, this is not a technical problem.<br>
2) active glasses ($150), Gforce card ($300), LCD 120 HZ monitor ($300), emitter ($50); only works on MS Windows, not sure if chimera supports this. <a href="http://nvidia.com" target="_blank">nvidia.com</a> Nothing is compatible with #1). someday may work with linux and mac.<br>
<br>
If you are doing a workstation and want to support a projector, you got two options, passive and active using an in-focus projector ($5-6k).<br>
You get full vertical resolution even if you are doing passive. If you do passive you will need a polarizer ($5k) and cheap glasses ($1-15) same used in the most movie theaters. If you do active you need a theater emitter ($500-1000) and active glasses ($200-300). Either way you are going to need a quadro card ($1800) in your workstation.<br>
<br>
In my lab we use all the methods except the polarizer, which is on order. I find the Zalman approach the least hassle and most recyclable, but for conference room setting with a number of people the polarizer is most economical, what the movie theaters are gravitating to, and has less operational failures.<br>
<br>

Hi Eric:<br>
<br>
I am looking into getting a new workstation for Chimera. In the past, we have gotten CRT displays in order to do 3-D visualization. Could you recommend other display options that are available now and that users have been happy with? Is a CRT still the best option?<br>
<br>
Thanks for the help.<br>
<br>
Ed<br>
