[Chimera-users] Fwd: Chimera 3-D viewing

[Daniel Gurnon]

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.

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.
