Screwed OPENGL-output under Processing 2.0 ?

in Core Library Questions • 11 months ago

Running the following 'sphere code' under Processing2x, Mac OSX 10.6.8, I get a screwed output like the one below.

import processing.opengl.*;

size(500, 300, OPENGL); //P3D is the same

background(128);

sphereDetail(80);

translate(width/2, height/2, 0);

sphere(100);

The changes appear more or less random and may differ with every new program run. Sometimes it looks like the image is first drawn correctly and then screwed immediately afterwards.

Using Processing 1.5 everything looks fine.

What is wrong?

Thanks

wow! i couldn't pay you enough to program that!

source code please ?!?

It is the source code provided above:

import processing.opengl.*;

size(500, 300, OPENGL); //P3D is the same

background(128);

sphereDetail(80);

translate(width/2, height/2, 0);

sphere(100);

Some library issue? (Have been playing with sound, sonia, minim and such recently. Maybe one of those JAVA updates.) A bug in Processing 2x? (Not sure whether I ever ran it under 2x.) And of course - human error.

Here's another one:

Well, on my computer, I see briefly the image (no artifact), then the sketch crashes with the message:

#
# A fatal error has been detected by the Java Runtime Environment:

In other sketches (using P2D or P3D), they work (more or less) and I see the above message when I stop the sketch...
Windows 7, relatively recent computer (less than 3 years), video card is ATI Radeon HD 5450 (probably low end), driver is up-to-date (Catalyst is updating itself regularly). OpenGL 2 doesn't seem to be supported well by all video cards.

Looks like that's not with Processing 2.0 that I will start to do 3D...

Ah, I just made two interesting observations...
If I add a draw() loop to your sketch, it doesn't crash:

import processing.opengl.*;
void setup()
{
size(500, 300, OPENGL); //P3D is the same
background(128);
sphereDetail(80);
translate(width/2, height/2, 0);
sphere(100);
}
void draw()
{
}

And if I stop the sketch with the stop button instead of the close button of the window, I don't get the error message shown above either.
I guess that the close button is more brutal, not letting Processing to do clean up work properly...

did so as well:

The error message I get is: java_home: unrecognized option `--request'

When using Processing 1.5 it (always) looks like this (same computer, just different Processing):

I had the same problem, see here

Solved (so far...) by upgrading to Processing 2.0b.6

did the upgrading as well - everything fine now - thanks for 2.0b6.
