Aversion 1.0: It's About Time

Posted by chet on September 4, 2007 at 12:14 PM PDT

I just posted Version 1.0 of the Timing Framework to the
project site
; check it out for the latest, stable version of the

There actually haven't been that many changes to the library of late. Partly,
this was by design: I didn't want to cause too much contortion between fully
documenting the library in Filthy Rich
and actually releasing the book. But also, since a major
refactoring of the code in late 2006, the library has been relatively stable
(and useful).

So if you've been using the previous version or two, you will probably not
notice any differences. But I figured it was important to declare a 'real'
version 1.0, rather than simply incrementing the pre-1.0 version numbers. It's
indicative of a lilbrary which, while not yet complete in all of the features
that I and others would like to see, is at least solid, stable, and
useable in its current state.

So for anyone waiting for a real version, go
get it
while it's hot. For those interested in the latest version of
the project, or in previous releases, check out the project site at
. For people just interested in the
library and javadocs, I added convenience links to the downloads for version
1.0 to the book's website at

There are clearly more capabilities that make sense to add to the library in
future releases. For example, I've been toying with the idea of an overall
"Timeline" for some time, but it just hasn't made it into the library
yet.  Also, I would like to tweak some of the default assumptions, such as
having non-linear interpolation by default; linear makes sense from an
analytical standpoint, but tends to produce unrealistic animations, so it makes
a poor default choice.

But I think that these things can wait. First we get this version out there,
then we continue to improve it. It's the way of all things - first you release
your initial, working product out into the world, then people start using
it, then you improve it in parallel. This approach has gotten us from
dumping human waste into the streets to today's lighted, heated, auto-opening
toilets. It's also given us such marvels as the English Muffin Splitter, saving
countless seconds of our lives and preventing the inevitable and aesthetically
displeasing uneven muffin halves. Now, we'll apply this technique it to the
moving target of animation libraries.
