Looks good, pretty much what I had in mind for a basic animation
framework.
Hi nicolai
I still do not fully understand it :)
I mean I could try to look smart and say yes. But there is a little
voice in my head that said that
I do not understand the little details. I think that I would have to
rebuild or check all the code before.
:)
so this is why I stay humble :)
How about making the animated value more generic and independent of a
timer, more
like a "binding"
source -> property binding -> target
and an (timer-)animated binding
timer as source -> property binding -> target
feel free to enhance it. Igor developed it in 2 days and we coded the
turtle as an example
so that I understand it but I failed :)
As I was thinking about an animation framework I got the idea of some
more generic
components. The components I had in mind:
Clock
EventQueue
Task
Binding or PropertyWrapper
Range (as a source for interpolators)
Interpolators
Transition/Animation ( connection of a source(timer) and property
bind, together with a range interpolator).
scaling/easing function (linear/quad/quadIn/quadOut)
Clock, EventQueue and Task classes (maybe we have some of them already)
may be usable for other things and are used here as building blocks
for the (transition/animation) framework.
(The idea is, to not invent a TimerFrameWorkClock/ TimerFrameWorkEvent
/ TimerFrameWorkXXX....)
I think that what would be interesting is a small framework so that we
could use it.
Do you know this Squeak (Morphic) Animation Framework
(https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki/animations)
?
I like how it wraps different property animation in different
animation classes (AlphaBlendAnimation/ColorAnimation ...).
No I did not know it.
I will add it to the list of things that I want to understand.
First I should study for real Viva.
(I wonder why it is nowhere used)
And there is GLMAnimation, but I don't like how it is implemented.
So several propositions:
- improve viva
- design your own (check in block because alain has the logic for
alarm and ticking)
- are you interested to participate to a paper that we want to send
to IWST on Viva (but it could be on
animation frameworks).
