<p>its about $3.5k, about $3k more than a s3D monitor. It is an open question for me to get it working, and it only works on windows. Compared to the $4M microscopes, nothing ventured, nothing gained...<br>

</p>
<p>If I can getting it working, I plan to have it in the conference room for general access. <br>

<p>If zspace does not go with HDMI 1.4 or 2.0, I do not see it making big penetration into the market. <br>

<p>head tracking is nice and pen interaction has benefits; but they may be marginal for operational work.<br>

<p>With all the USB-HID I am doing, a 3DTV may be the affordable ticket. <br>

<p>This looks interesting for $950. </p>

<div>Hi Matt,
<div class=""><br class="">
</div>
<div class=""> Peter Ullman of zSpace visited our lab and showed us the device in October of 2012. We thought it was neat but too expensive (I think it was $3000 for a display, glasses and stylus), meaning few Chimera users would buy one so we did not add
support for it in Chimera. I suspect the situation is the same now. I can’t find the price online — you only see secret prices for goods that are expensive niche products. I saw an April 2013 post that said it was $4000 but they expected it to be under
$1000 within 18-24 months, which would be now. Even at $1000 I would not expect more than 10 total Chimera users of the device worldwide if we supported it.</div>

<div class="">You could also try turning on the Camera's experimental autoFocus capability:<br class="">
<br class="">
chimera.viewer.camera.autoFocus = True<br class="">
<br class="">
It tries to maintain the focal plane at the same relative position between the hither and yon planes. I don't recall why it is off, it must have interacted badly with some other feature. But it might work for you :-)<br class="">

<div class="">Hi Matt,
<div class=""><br class="">
</div>
<div class=""> Here’s some Python that will update the focal plane position to always lie midway between near and far clip planes.</div>
<div class=""><br class="">
</div>
<div class=""> If you zoom by moving a map or molecule closer to you (z translation) then visually the map should move from behind the screen to be in front of the screen so it looks like it is coming closer. In other words the map moves forward and the
focal plane that defines the position of the screen stays fixed. That is normal Chimera behavior. The above script will defeat that. You will move the map closer to you in z, but what you will see in stereo is that the map gets bigger, but no closer. It
instead feels like a magical scaling of the map, rather than getting closer to it. This isn’t natural, but I understand that because of the limited 3d depth with stereo viewing it is necessary to do something to avoid uncomfortable stereo where the models
are too far in front of the screen. An optimal solution is more subtle than the above script. In fact the above script won’t prevent getting the front surface of the map too close for stereo viewing because it keeps the focal plane at the map midpoint in
z. The front of the map can still get close to your eye and the stereo will not work. Basically you want to avoid having the front visible part of the models from getting too close to your eye where the stereo glasses don’t work (because the display screen
is not wide enough). We have not worked on techniques to avoid stereo interactive viewing limitations. But the normal Chimera zoom uses scale factor, not z-translation, so that is the main way this problem is avoided. But you are using z-translation instead
of the normal Chimera zooming and that is why you encounter this problem.</div>
