View Full Version : AF challenge: Tracking Arrow

04 April 2005, 06:08 PM
I have set up some tracking in my animation successfully, but I want to point at the tracked point with an arrow. How would I go about doing this using the tracking information? The tracking is being used to label parts of a medical animation.

Uh, create an image of an arrow, put the pivot point of the image to just in front of the arrow, track that image to your tracking data.

Sorry, I knew I wasn't specific enough. I found what I was looking for below. A better way to describe what I was looking for is a way to connect two moving points. In this tutorial you use the 'beam' effect, and link the two end points to the two other points you want to connect to.

Thanks for the help.

Wow. That's why I don't use AE. Look at the steps to track two points and connect them. Glad you found what you were looking for.

That tutorial connects four points with for lines, so I don't think that its too bad. Unfortunely I work at a small company that didn't do any compositing until now, so AF was the ignorant choice. It certainly is frustrating to spend time learning a tool I hope to eventually move away from.

Anyway, while I have you attention, what do you think is the best forum for visual effects and compositing? I saw in your signature, but that forum seems rather small.

While VFXTalk is small, there's a wealth of good information, just do a search or order threads from the beginning. The caveat with vfx forums is that it is a MUCH smaller group of people than general CG, one of the reasons why CGtalk is so huge is because it covers so much, 3D, painting, graphics programs, anything computer graphics related.

Not as many vfx specific professionals have time to contribute to forums, but the ones that do have some interesting insights. Check it out, search, and ask questions. Lots of talented vfx artists there, and some great in-depth comp interviews. Some other ones which have forums but have even smaller communities are and

Hope that helps!
