Hello everybody,
I need to put some dynamic drawings on my web page. More precisely, I
need to draw a number of geometric figures (circles, rectangles) which
evolve into a graphics windows according to some law (a little bit like
the solar system). I need also to have several fields aside the window,
where the visitor can change values for several significant parameters
(like the mass of each body).
Could you please suggest a solution (preferably not involving hundreds
of lines of code) ? The computations should be performed on the client
machine.
Thank you. Cristian Barbarosie http://cmaf.fc.ul.pt/~barbaros 5 2073

Basically, it sounds like you're talking about writing an applet. An applet
is a Java program that sits on a web page. You can write an applet so that
it draws circles, arcs, etc. and you can give the user the ability to
interact with an applet.
If you look at the sample applets that Sun has written for Java - http://java.sun.com/applets/jdk/1.4/index.html -
you'll see that a few applets are doing at least some of what you want to
do. Each example includes source code so that you can get a rough idea of
how much code is necessary to do what you want.
In your case, you might want a single applet with several distinct canvases
for drawing or a separate applet for each canvas; either way could probably
work.

In the context of recent Flash-related discussions and the usage of
open Web standards, I searched for 'animation SVG "solar system"' and
discovered this example: http://www.svgelves.com/svg/L_chrisa_02.svg
Sadly, it only works in Opera amongst the browsers I have. Konqueror
displays the initial frame but doesn't animate the scene, although
later versions of that browser might support animation. I have an old
version of Firefox which doesn't support SVG at all.

It also works under IE6, using Adobe's SVG Viewer 3.0

have a look at the code for the http://mindprod.com/applets/bio.html
biorhthms Applet. It will show you the general framework. It may be a
bit to complicated though. Also look at http://mindprod.com/products.html#SCREWS
