What version of Windows are you using?

What version of directX is installed?

What kind of video card do you have on your system?

Hello, my previous problem is solved, thanks, now I have six cameras and working properly calibrated and the calibration of the skeleton made. I have also created a rigid object, from a model you have in the software arena, but now I want to create another set that is not how I do it? What should I consider?

Thank you very much

Hi, another question, What is the option Export BVH and C3D? With what program can I run?

Thank you very much

bvh is a file format used by many 3d packages, such as Poser, 3ds max, Maya, etc. It basically tells the software how to move the character. It is skeleton based (for example, arm, leg, etc)

c3d is a different type of mocap format, marker based, for use in programs such as Autodesk Motionbuilder...

Yes, you would create a second rigid body the same way, just have an asymetrical marker configuration, that is different than the first, and rename it within the wizard itself.

Hi, I wonder if there is a minimum distance to place the marks to create a rigid body, I would also like to know that once you have created, this remains in the soil, and is not on marks where I've created.

Thank you

Rigid Body Sizing
The physical arrangement of the markers should not be too small and should not have markers too close together. Markers closer than 6 millimeters can result in the following issues :

* Markers are more likely to overlap or occlude one another when seen from a camera, resulting in incorrect 3D position data or markers failing to be tracked.

* If the point cloud tracking residual value is too high, or the calibration is poor, then rays for adjacent markers could be grouped together incorrectly resulting in misidentified marker locations and/or falsely reported markers.
