PFtrack problem

#1

I have a shot which the camera is stationary and I have some geometry I want to track (small buttons), but I’m not able to get any tracking at all, not even for a frame (both front and backwards).

Then I went on to matchimate it (hand tracked it with geometry), hoping that it would give me tracking data for each group (button).

I can see it in the perspective view and it looks fine there, but when I open the scene in maya, it’s just en empty group and no animation (althou it has keys on every frame, but there just in origo the entire time).

Is there a way to force “solve it?”.

It has a solution, but it seems not to be “solved”.

Are you using geometri tracking? You should, I think, it’s extremely fast and very precise. Since version 5 it has a bug or something, change the display mode to wireframe when you are arrangeing the geometry and solve. For me it helped.

hey obi
can u plz tell me the steps of using geo tracking…
m using maya…
bt whn m making a obj in maya and exp. it in obj format to pftrack…its nt talking any features in pf…

Hey DJhush. geo tracking is very simple.

go to file-import tracking geometry. this should take you to the primitives folder. you then open the shape that suits you scene e.g. a box for a building. you then just postion that box and track forrward or backward. you will have to keep tweeking the shape everytime is goes outta place.

Hey guys.

Thanks for the replies, but my problem wasn’t geo tracking (I’ve done it numerous times, and yeah, it kicks ass :-).

My problem was on the first hand that my geometry was too small to track, so I had to matchimate it by hand, and when I did that I didn’t get a solve on the object. I couldn’t find a solution for this at the time, so I finilized it in Maya Live instead (I copied the tracking information in the 2d-trackers and exported the animation to locators).

It was good enough for a 2d solve on each object and then I had to handanimate it with rotation/scale.
