i just created an animated camera that turns 360 degrees around a scene.
I started at a random angle that was not 0.0, so to not have a discontinuous animation i did:
selected the rotN vertex in the IPO editor for frame 1
add approximately 20 to it
store that value in the rotN vertex in the IPO editor for frame 250 (end frame).
So i added approximately 20 to get a 360 degree turn that does not cross 0. The animation is continuous and looks ok.
But to find that value of 20 is somehow strange to me, can somebody please explain why 20 (as a Y-difference in the vertices in the IPO editor) are 360 degrees (or 2 * M_PI) ?
If I want continuous animation, I just set a couple of keyframes then change the curve extend mode to extrapolate.
One thing that is off in the IPO window is that the values are divided by 10 for some reason. I just rotated the default cube from 0 to 360 degrees. I can see the 360 along the left hand side of the window, but when I select the end IPO point and press the N-KEy to bring up it’s value, I see that the value is actually -36.0.
You can call it a bug, but I think there is no effort being made to fix this.
