NP TrackClip Pivot

[GoogleCodeExporter]

I'm curious where the NP TrackClip pivot is located. When a location is 
returned from the tracker, where does that point lie relative to the three 
tracking markers?

Thanks for your help.

Hi,

I'm not sure if I'll be answering the question you ask, but I assume you are 
talking about the relation between TrackClip and the point that is being 
returned as the [tx,ty,tz]...

The idea is this: the point that is returned is assumed to be the pivot point 
around which the head rotates. The aim is to have this point stable when you 
rotate your head.

Position of this point is influenced by the model fine-tuning sliders and to 
get the numeric value, you have to take a peek at your linuxtrack1.conf file 
(in ~/.config/linuxtrack) - look for Head-X, Head-Y and Head-Z values. These 
are offsets from the model's reference point (for TrackClip it is directly 
below the high marker on the level of the low markers, for TrackClip Pro it is 
the middle point). For exact points, see the pref_global.c source, and look for 
functions setup_cap and setup_clip.

Kind regards,

Michal
