View Full Version : Y Position different than 3.0

01-24-2012, 02:01 PM
Hi All,

Did anybody experience any differences in Y positioning when going from Vizard 3.0 to 4.0?

We are using an intersense I-900, and although the position outputs the same, the viewpoint seems to be a couple of meters lower in the few scripts I have tested so far. I have tried experimenting with the eyeheight but it doesn't seem to change anything. It only happens when tracking is enabled. Anybody have this issue?

Are you linking the sensor to the viewpoint? In 3.0, the eyeheight would be added to the Y value of the link source, unless the viz.LINK_POS_RAW flag was used. In Vizard 4.0, this is not the case and the eyeheight is ignored when linking.

I was linking and that seems to be the issue. Would the best way to modify old scripts be a postTrans on the link position, adding default eyeheight to the Y position?

Yes, you can use either the postTrans or setOffset commands to add an offset to the Y position.
