Saving the feature points with the Voodoo Camera Tracker generates one .pnt file for each input image.
Each line in this text file represents a 2D feature point:

x y manual type3d px py pz ident hasprev pcx pcy support
x : x position of 2D feature point in that image
y : y position of 2D feature point in that image
manual : manual feature point (1 yes, 0 no)
type3d : 0 for no 3D point, 1 for Spherical, 2 for Cartesian
px : x position of 3D feature point
py : y position of 3D feature point
pz : z position of 3D feature point
ident : unique identifier for a 3D feature point
hasprev : has a previous feature point (1 yes, 0 no)
pcx : x position of 2D feature point in the previous image
pcy : y position of 2D feature point in the previous image
support : inlier / outlier bitmask

If the feature points have the same ident in different .pnt files they are on a common track.
