Introduction
On this page we show a number of predefined marker setups for our VIVE Pro target. optical marker target. These files have been created using our automatic calibration algorithm or data from the manufacturer and are a very close approximation of an ideal configuration.
For each setup we provide a corresponding body calibration file that can be loaded into ART DTrack. After loading the file, please do a re-calibration (using the recalibration functionality of DTrack’s body setup dialog). The body should now be accurately adjusted to provide a perfectly realistic VR impression to the user.
