View Full Version : Rotaton and Function Curve

I have a project where a cube starts rotating on the Y axis at a constant rate, 3 seconds into the rotation, the cube needs to quickly spin 360 (the rotation will be completed in 1 second) then the cube would resume it's normal rotation rate for the remainder of the animation (8 seconds). I have played around with the function curve editor and have come up with something close, but if there is a way to assign a value to the keyframes to make the process easier, it would be appreciated. It also has to loop seamlessly.

Thanks!

Hey, I got it figured out. All it took was a bit of math and some tweaking of the F-Curves.

Hi!

Yep. Function curves are the way to go. I've been spinning objects for weeks now and without F Curves it doesn't work very well.

Figuring out the math so that the front and back of the box would show after the spin took a bit of brain time (at least for me :o). One thing that helped was keeping the Function Curve window open as I added keyframes and adjusted the amount of rotation. The curve would pop into the proper shape if I did the math correctly.

Here is another test, the actual product will be dropped in after it's modeled.
