I found that when I dropped the patches in favor of a PHP parser or
put them in a render in image patch that I then turned off, the
framerate increased substantially. This was with 10.4 Tiger if it
makes a difference, but to me it seems the less patches the better,
although if I'm wrong that does make this process easier.
Namaste,
Karan

Hi!
Karan, I don't really see how using an RSS parser that is done by a
RSS Downloader and some Structure patches should slow down
performance. As soon as the patch has downloaded the data, it won't
do anything until the next time the "Update Signal" input port of
the RSS Downloader is set to true. The same applies for all
downstream Structure patches. In short: the parsing is done exactly
one time and disabling the whole bunch of patches that does this
after one second won't make it any faster. On the contrary, this
could introduce unwanted behaviour. Just think about a slow network
connection...
Anyway, David, I'd suggest you use a XML Downloader patch in
combination with a few Structure patches to do this. I have done
quite a few things in that direction already and it works really
well. For example, I used the service by weather.com, who provide a
really great XML weather feed that is nicely documented, detailed
and customizable.
Maybe you'd like to take a look at the SQLite patch example in /
Developer/Examples/Quartz Composer/Plugins/SQLiteQuery if you want
to use a SQLite Database in background (works great in combination
with Core Data).
There are whole video distribution systems up and running using
Quartz Composer that are controlled by a server using XML of some
kind. You just need to define your XML scheme and do a editor for
that. The part in Quartz Composer is easy.
Greetings,
Marco

My main project in QC is something along the lines of this. You
can parse an rss feed entirely in Quartz Composer, but that can be
cumbersome, and slows down the rendering time. You can throw the
parser in a render in image patch, and then set it to render for a
second and then stop, and then you'll be left with a static image,
which will increase the framerate, or you could write a parser in
PHP and have the RSS feed patch download from there. I like the
third option, as it's the fastest.
Namaste,

Good Day All..
Haven't played with Quartz Composer for a couple of years,
wondering if things have changed..
We use a eMac hooked up to our school's video distribution system
to display student made DVDs, class projects and a daily PowerPoint.
I'd like the presentation to be done with Quartz as a screen saver
since is it much NICER than PowerPoint. But I'd like Quartz to get
data that can be inputed by a student (k-5 student) and read from
a text file. Such as classes with perfect attendance, today local
weather, etc...
Is this possible with todays Quartz Composer? If so how? Anyone
have an example online..
I can do the basic stuff (i.e.: Globe with real time weather cloud
cover, time, date), but I'd like to advance my skills.... Perhaps
using Automator or Apple script with Quartz Composer.
Thanks
David - CST/CET
