[Compcomm] Animation depricating Minimize. There is one last thing that minimize can do

[Erkin Bahceci]

Hi,

David is planning some changes on how vertices are generated and animated:
http://lists.freedesktop.org/archives/compiz/2007-April/002020.html
http://lists.freedesktop.org/archives/compiz/2007-April/002040.html

Therefore for (2), I would wait for those changes, otherwise anything
done now about that will probably have to be rewritten when he changes
how things work.

We could ask David to consider such interactions between plugins while
he's working on or planning those changes. This could be done by
putting the grid locations of vertices (where each vertex falls on the
rectangular window grid) into the core just like the vertex positions,
so that different plugins (e.g. wobbly and animation) can manipulate
the vertices (depending on those grid locations) simultaneously by
"adding" their position/orientation changes for vertices instead of
setting "absolute positions" for them. The number of vertices (or the
grid resolution) has to be set in core options in that case. I don't
know if this is what you or others want though. Any comments on this?

For (1), the velocity model "dx = f(v)" (for some function f) used by
Minimize is not "much more flexible" than just using "x = f(t)" (for
some other f). It's just a different way of doing things. It's
actually more limiting in some ways, like not being able to accurately
control the positions of points. However, I do like the springiness of
Minimize's zoom. So I can consider the springiness for some animations
(Sidekick, Zoom, and the (future) minimize variants of the fold
animations).

And about the replacing thing, the core is going to stripped off of
plugins anyways (as David said). So what do you mean by Animation
replacing Minimize? Do you mean that Animation will be distributed in
the composite community package/distribution by default instead of
Minimize? I thought that already was the plan :)

Cheers :)
Erkin
