Hi Everyone,
Well, I am sure that no one will be surprised that my best method of animation with SU is Keyframe Animation.
But that is not why I am posting here. I would just like to clarify the differences between my plugin, Keyframe Animation, and SU Animate's new key frame animation feature.

SUA recently released a pretty major update that now includes key frames. I've toyed with Keyframe, but haven't used it for anything so I don't know how it compares.

i also have su animate and with the current release of the new version last month i believe it has its own version of keyframe animation, havent played around with it as of yet but i suggest try it out in su animate before buying keyframe animation, im sure they both do the same from the tutorials iv seen
SU Animate recently came out with a new feature that they claim supports Key Frame Animations. I released a plugin last year named Keyframe Animation. Since they are both called the same thing, I suppose everyone just naturally assumes that they must do the same thing. So, that is the misconception that I would like to clear up.
First of all, SU Animate V4 does not interpolate rotations correctly. It has exactly the same problem that you may have experienced with Proper Animation. They both rely on a buggy method in the SketchUp Ruby API, which does not interpolate rotations correctly (unless the axis of rotation passes through the origin of the component). Keyframe Animation, on the other hand, uses my own algorithm to interpolate rotations correctly about any point or axis.
Oh, yes, I know what you are saying. There is that video of SU Animate that βprovesβ it can rotate objects between key frames.

The door rotates correctly in this video because the edge that they rotate about just happens to pass through the origin of the door's component. If they had tried to rotate the door about the opposite edge, things would of got ugly. Really, most rotations, like 99%, are not going to be interpolated correctly. So, this video may be a bit contrived.
OK, I digress... Another difference is that Keyframe Animation allows you to animate subcomponents and subgroups. It is very general, you can nest animated objects inside one another to any depth. This lets you move objects relative to one another like in this mannequin video, or this video of the rolling gears. The SU Animate key frames feature, on the other hand, does not permit you to animate subcomponents or subgroups.
Those are the two main differences. Both plugins move objects along a straight line correctly. Both plugins animate the visibility of objects. They both export the animation to a movie.
Hope that clears things up somewhat.
