Different behaviour Windows / Linux ? (Read 753 times)

Different behaviour Windows / Linux ?
Oct 31st, 2006, 8:59am  
Hi,

I hope I am in the right section - I am new to processing and I didn't find the Bug session.

On Windows my applet works like a charmm - on Linux it breaks. I use processing 0119 btw.

The only thing I use is core.jar and P3D Mode - I thought this is platform-independent, so why the error ?

Can anybody help me ?

Cheers,
sb

Very late reply, but if you read the error it starts off by saying "Too many calls to popMatrix() (and not enough to pushMatrix)". Fix this bug and you'll have a bigger chance of making it run on all platforms. Smiley

I can confirm I am getting the same error. This simple program below will produce this error. Strangely it doesn't always happen the first time I play the sketch but the 2nd or 3rd time it will throw the "Too many calls to popMatrix() " error.

void setup(){
 size(400,400,P3D);
}

void draw(){
 background(0);
 translate(width/2,height/2);
 sphere(100);
}

I am running Ubuntu Feisty 7.04
Unfortunately I am new to Linux and wouldn't know where to begin trying to fix this but maybe these observations are helpful to someone who does?
