Mask Data Used As Camera Path?
Posted by Bernd Garving on July 13, 2005 at 4:54 pmHi there …
… I’d like to use data of a elliptical mask as data for the path of a camera. I copied the mask’s shape into camera’s position. But what do I have to do to tweak it into the right dimension?
Thanks in advance.

July 13, 2005 at 6:06 pmI m not exactly sure I understand what you mean, but mask data is 2-dimensional and will end up in the X and Y position values. Z is just left empty (assumed to be zero). If that’s your problem, just switch the values using a simple expression.
X=position[0];
Y=position[2];
Z=position[1];[X,Y,Z]

September 30, 2010 at 6:46 amI found this post and thought it might help me, but it needs some tweaking…
I have text aligned on a 3d path (spiral, pretty much exactly like Eran Stern’s tornado here: https://library.creativecow.net/articles/stern_eran/Tornado_Text1/video-tutorial.php
He has the tornado going around his subject, but I am trying to animate the camera along the spiral so the words appear when I need them to (with music)
I’ve tried pasting the mask data from my words onto the position of my Null (Camera is parented to null) and using your expression to rotate the mask along the X-Z axis, but the path remains along the X-Y axis, so it’s a bunch of guesswork to get the camera to line up with the words in the spiral.
I’ve tried rotating the spiral around the camera, but I also want to add some other objects to the middle of the spiral so it gives a cool sense of motion around the spiral, but getting all the anchor points to line up and the camera to go to the right words at the right time is a tedious hassle, and I’m thinking there’s got to be an easier way. Thanks All
