Expressions and Camera Movements
I need some hand holding here……I have 40 stills set up and stacked in a cube-like manner (front, back, left, right, then stacked ten high, like a ten story building). The next thing i need to do is to animate a camera, essentially to circle this “building” while ascending it. What would be the best way to accomplish this? Or script it?
I’ve pilfered this script “[Math.sin(time)*100,120,Math.cos(time)*1000]” from a tutorial, it doesn’t quite circle the building, it does a more half moon. I’ve then tried taking a null object and run it up the center of this “building” and tried to attach the camera to it to accomplish the ascending portion of the movement……thats not working.
Am i going about this correct? What am i doing wrong? What kind of expressions should i be using?
I hope this makes sense
cheers

i think this can be accomplished without any expression. here is a dirty way to accomplish what you want.
create a 3d null and place it “inside” your building. make sure the null’s anchor point is exactly centered if you want the rotation to be even.
place the camera where you want to start. parent the camera to the 3d null. now you can animate the Y rotation of the null, this governs the speed of the camera’s rotation.
animate the camera however you want, just disregard the rotation part. I think in your case just use the XY camera tool to “ascend” the building.
here is a quick video i made. it took less than 3 minutes to make, but it sure is sloppy. is this what you are looking for?

That’s what i’m looking for, i just tried it and it’s going to work.
