FOr some reason the color settings don’t seem to work. Did I just get the wrong version? The color always seems to be a mix of purple and yellow regardless of the settings.
You have to update your Xith3D.jar 
I was the one who discovered that bug in setColors with the previous builds, but it’s been fixed with November the 13th release 
WHere do we get the new xith3d.jar
I’ve been checking out xith3d from cvs so I assumed I would have the newest stuff all the time but I just checked and my xith3d.jar is from october 11th.
I’m connecting to cvs through the server
cvs.dev.java.net/cvs as a guest
then I go to the xith3d folder and check it out as a project.
Am I going to the wrong cvs??
Also,
could you explain to me briefly what the updateMatrix() method does in ParticlesManager.java. What is it used for? All the variables and such just make no sense to me and it’s a pretty long method.
If you use CVS you need to build xith3d.jar yourself. This requires Apache Ant. If you already have it, just type “ant” in the Xith3D base directory.
Java Cool Dude probably downloaded the release here.
I’m pretty new to ant would any of you know what this error means.

Is it getting confused cause I’m on windows and there is a space in the directory path (c:\program files)?

Ooops looks like I have to change the variable names in that method, the way they are now reflect how much trouble I went through to set it up and get it all working :P.
What it does basically is rotating the up vector (0,1,0) so that it’s aligned with the emission direction.
I could have skipped that part and implemented a method where you have to input the x,y and z angles of rotations to get the emitter shooting in a certain direction, but that would make it a bit harder for my coworkers to implement it in our current project.
Especially the case where particles have to come from a volcano on a non-flat planet (sphere).

Yes, exactly.
Check the value of JAVA_HOME environment variable and set it to JDK 1.4.2 home (say, on Windows machine I have
JAVA_HOME=C:\j2sdk1.4.2_01\
Then it should work [again, hopefully].

why microsoft uses spaces in important system directories I will never know.
Will.
First attempt at WS:
Does this work?
Pretty much done with this demo, time to move on to something else
Fraid not, looks like your webserver isn’t configured with the correct MIME type mappings. Either get your admin to modify the apache/iis settings or use a PHP/Perl/JSP frig to modify the MIME type dynamically

Ok, now you need to change your href to be “particles.php” instead of “particles.jnlp” cause you changed the name

Better flame and smoke effects.
Probably one of the very last updates if not the last.
