[Question] Keyframing

[robinsonkwame]

Great work! I had a question after reading the technical report, on keyframing. Has this feature been considered further? Several other projects, such as War and Peace, seems to approach the issue but not as systematically as your paper touches upon it.

Interesting question, the 'scene' mechanism, which we added after writing that sentence in the tech report has, at least for our purposes so far, seemed to be the right idiom to handle the same underlying issue which the keyframes were meant to handle.

Here is an example of how scenes can be used to structure the simulation:

Of course keyframes would be for a somewhat different purpose though. We just found that we didn't feel like we still needed keyframes after we added scenes. But maybe we're wrong and some situation will arise that will make us want to add them. This is a fast developing space.. We'll see...
