Hello,

Hello,
I'm just writing to mention that there is a serious problem with Processing 2.0b7 on older Macbook Pro 17" with Radeon X1600.
some sketches using just size(x,y) from the Examples seem to work OK, anything that uses P3D or P2D runs with garbage on screen (like random parts of the graphics buffer flashing)

running SpecTests brings me:

I have no trouble running the examples on my windows machine

Hello,
I had a nice 'largish' personal project working fine for a while, now I am trying to get it to work using Processing 2 beta. I have jumped through some hoops already, like the XMLElement -> XML change, or the new more strict validator.
I am however still having problems,

1. Exception in thread "Animation Thread" java.lang.NullPointerException
       at processing.core.XML.getString(XML.java:442)
       at processing.core.XML.getString(XML.java:437)
       at zmidi.ZMidi.openSceneList(ZMidi.java:398)

the lines in questions are just:

1.     xml = new XML(this,fn);                                          // default xml
   
2.    //  xml = new XMLElement(fn);                               //proxml
   
3.        int numScenes = xml.getChildCount();
4.        println(numScenes);                                            // reports 35, an incorrect number of scenes, there are 17
   
5.        for (int i = 0; i < numScenes; i++) {
   
6.            scene = xml.getChild(i);
   
7.             String name = scene.getString("name");        // this is the reported line
   
8.             println (name);                                                // never gets here
   

it there something that one is suppose to do very different with the new library?
Should I check if it has a string with that name before I try to read it? I didn't have to do it before, it would just return null if there was no string.

Hello
I'm writing a thingy using GLgraphics, and I'm trying to load an SVG an display it several times. As long as its only a few repetitions of a very simple shape it's all good, but as soon as the shape becomes more than a few verts or number of repetitions gets above 20-50 it all slows down dramatically. I'm guessing PShape goes through curve list every time for each object which is redundand as the shape will not change in runtime.
 I'd love to be able to put the shape in the GPU as GLModel and request drawing it in different positions, but I must admit my opengl knowledge is poor and I'm having trouble fully understanding the glmodel examples, and so far I have failed guessing a way to do it (there's verts[] but also glmode and I am not sure how would triangulation of the shape work and do I have to do it on my end using geometrative or something).
It would be great if someone would point me to a right direction. Thanks           

Hi.

Hi All,
A question from relative newb: I'm trying to achieve the following:
draw left and right eye onto seperate textures using GLGraphicsOffScreen, than display them one on top of another using line interlaced masking (for my stereoscopic screen), and I think I'm stuck.
I don't feel fully ready to get into low-level GL calls yet, and GLGraphics seems like a good choice, I cant figure out however if it's possible to affect alpha only. Ideally I would draw my interlace pattern once and just 'freeze' alpha channel somehow, so following drawing methods ('line' and 'rect' mostly) would not affect the pattern.

The idea is that if later on I swich to a different displaying technique having both eyes in two offscreen buffers is not a bad starting point for further work but for now would just want to see what I'm doing on my 3D screen (which displays left and right eye in a row interlaced fashion)

I'm trying some dirty workarounds at the moment :

1. alphaImg=loadImage("alpha.jpg");
2. texture1=loadImage("random_image.jpg");
3. texture1.mask(alphaImg);
4. texture1.loadPixels();
5. texture2.putBuffer(texture1.pixels);
   

which does seem to load alpha values correctly, but as soon as I do ...

1.  texture2=glg1.getTexture();

...it's (obviously) gone and doing any of that (based on offscreen example)...

1.  glg1.beginDraw();
2.  glg1.ellipse(random(0, glg1.width), random(0, glg1.height), random(10, 50), random(10, 50));
3.  glg1.endDraw();

...just overwrites my buffer (adding some rubbish in the background too). Funny thing is that even if I only do getTexture once in the Setup, it still updates the texture as I draw onto the glg1

So the question is: is there anything I can use (term FBO sits in my head but I don't want to sound silly trying to put it into a sentence) that would keep my alpha and use it for masking the display of the second texture?

I'd rather leave my drawing to the library but if I need to learn manual GL now - that's what I'll have to do.

Am I even barking at the right tree?
Thanks a lot for any tips
