Re: Calibration 18 cameras v100 R2

lying on your back and waving the marker above you, can help quit a bit with the single marker calibration, as an example.

Re: Custom Skeleton Setup - Motion Builder streaming

<t>Quite a few. It's all about placement and number of cameras. I usually start with chest markers. And I often have some facial markers as well. <br/> <br/> I've been experimenting with alternative hand marker sets. <br/> <br/> There is room on the thighs and shins. <br/> <br/> I sometimes do an ex...

Re: .net wrappers for c++ SDK

<r>Just a note: I'm putting thought into how best to update the wrappers and keep them up to date more easily.

Re: Custom Skeleton Setup - Motion Builder streaming

<t>If you augment the standard skeleton with xtra markers, you can select only the markers from the standard set and the auto fit will work based on the selection. <br/> <br/> Much like you can select three markers for the t square to force it to align the volume. <br/> <br/> This way, You can marke...

residual in "w" ordinal of c3d files

<t>Any chance you all could populate the "w" value of a point in c3d, with the residual, as per the c3d spec?<br/> <br/> Since systems can have more than 8 cameras, I think the camera coverage section of that value is not so useful. Though it would be really nice to be able to get the number of cons...

c3d format compliance

<t>Not exactly a request. More informational.<br/> <br/> The c3d file you guys dump out of Arena is not really compliant to the spec.<br/> <br/> It has no Analog or Force Plate parameters.<br/> <br/> The spec is pretty clear that these should be there, even if there is no analog or force plate data....

Re: Units of SetExposure method

Also, keep in mind: There are specific types of lighting that are designed to work with high frequency shutters. They are typically used in film making.

Specifically: HMI lights and Kino Flo lights. Kino Flo in particular is primarily designed to deal with shutter issues.
