using ControlP5 and GLGraphics at the same time?

using ControlP5 and GLGraphics at the same time?

in Contributed Library Questions • 2 years ago

hi there!

short question: is it possible to use the ControlP5 library AND GLGraphics at the same time? i am trying to do that, programm compiles, but gives an exception:

java.lang.RuntimeException: Too many calls to pushMatrix().
    at processing.core.PGraphics3D.pushMatrix(Unknown Source)
    at codeanticode.glgraphics.GLGraphics.pushMatrix(GLGraphics.java:271)
    at processing.core.PApplet.pushMatrix(Unknown Source)
    at controlP5.ControllerGroup.draw(Unknown Source)
    at controlP5.ControlWindow.draw(Unknown Source)
    at...

I implemented a deeper matrix stack, but this gives me another exception:

Exception in thread "Animation Thread" java.lang.NoSuchMethodError: processing.core.PImage.getCache(Ljava/lang/Object;)Ljava/lang/Object;
    at codeanticode.glgraphics.GLGraphics.renderTriangles(GLGraphics.java:1145)
    at processing.core.PGraphics3D.render(Unknown Source)
    at processing.core.PGraphics3D.flush(Unknown Source)
    at processing.opengl.PGraphicsOpenGL.endDraw(Unknown Source)
    at codeanticode.glgraphics.GLGraphics.endDraw(GLGraphics.java:239)
    at processing.core.PApplet.handleDraw(Unknown Source)
    at ...

Sample Code is:

import processing.opengl.*;
import codeanticode.glgraphics.*;
import controlP5.*;
public int myColorBackground = 200;
ControlP5 controlP5;
void setup() {
size(400,400,GLConstants.GLGRAPHICS);
controlP5 = new ControlP5(this);
controlP5.addSlider("myColorBackground",0,255,100,140,100,14);
}
void draw() {
background(myColorBackground);
}

thanks in advance for any hints,

micha

The second error looks like the one I get when accidently try to run GLGraphics with newer versions of Processing. As far as I know the current version of that library should be used with Processing 1.2.1. Did you try that?

hi andreas,

first of all thanks for the quick answer - and sorry for forgetting to post any system and program specs.

so, just tried it with 1.2.1, same problem.

i am on a pc running win7 64-bit, 32-bit jvm
processing 0194 and 1.2.1
glgraphics GLGraphics-20110411
latest controlp5 from last year

hi, i get the same behavior with 0194+ and 1.5 using GLGraphics 0.9.9 on osx 10.6. using controlP5 and glgraphics together under 1.2.1 works for me. the message 'Too many calls to pushMatrix' happens due to the following error message which is thrown in between a pushMatrix/popMatrix call.

java.lang.NoSuchMethodError: processing.core.PImage.getCache(Ljava/lang/Object;)Ljava/lang/Object;

at controlP5.Label.draw(Label.java:198)

you can get the same error when using the LoadDisplayImage example with the glgraphics renderer (see/use code below). assuming from andreas' post above, maybe there is a conflict with glgraphics and processing 0194 (and above) when rendering images?

import codeanticode.glgraphics.*;
import processing.opengl.*;
PImage a;
void setup()
{
size(200,200,GLConstants.GLGRAPHICS);
// The file "jelly.jpg" must be in the data folder
// of the current sketch to load successfully
a = loadImage("jelly.jpg"); // Load the image into the program
noLoop(); // Makes draw() only run once
}
void draw() {
// Displays the image at its actual size at point (0,0)
image(a, 0, 0);
// Displays the image at point (100, 0) at half of its size
image(a, 100, 0, a.width/2, a.height/2);
}

to use glgraphics with controlP5 in the same sketch for now you could try an extra ControlWindow.

When I run your code on 194 or 1.5 I get the described error but with 1.2.1 it works without a problem. I use the same library versions as far as I know. Maybe some caching problem when starting 1.2.1 after 194? I really believe it should work with the processing core from 1.2.1.

GLGraphics is currently broken in Processing 1.5. I'll upload shortly an updated version of GLGraphics that fixes this incompatibility.

Ah, nice! That was quick, thank you very much! Now my GLGraphics sketches work with 1.5 and I can ditch Processing 1.2.1.
