GLAdapter for Processing

GLAdapter is another way to run OpenGL /P3D. Both, Processing API and GLAdapter, use the same native libraries (JOGL) but obviously over different implementations . As Processing increased its version to 2.0 and higher my platform began to crash so I was forced to find a way to patch this bug. Let's suppose I'm not the only one with this problem so:

download GLAdapter.zip here

then unpack and install manualy

GLAdapter emulates a selected part of Processing API (P3D). It has the same names , accepts the same input params and shows the same output behavior. But the performance is not very sexy. Every usage start with this sample stub:

import ch.dieseite.glemulator.GLAdapter;
GLAdapter adapter;

void settings(){
	size(200, 200); //leave Processing in 2D

void setup(){
	adapter = new GLAdapter(200, 200);

void draw(){
	adapter.background(200);// An API example (see also list below)
	adapter.repaint();  //flush jobs, must ALWAYS be called at the end

There exist a class "GLBaseTest" which creates some test shapes.

Following functions is supported by GLAdapter:

  • void lights()
  • void strokeWeight(float w)
  • void stroke(float r, float g, float b)
  • void line(float xa, float ya, float za, float xb, float yb, float zb)
  • void translate(float x, float y, float z)
  • void rotateY(float angle)
  • void rotateX(float angle)
  • void rotateZ(float angle)
  • void scale(float v)
  • void beginShape(int mode) (supported mode "GLAdapter.TRIANGLE" only)
  • void endShape()
  • void fill(float r, float g, float b, float t)
  • void fill(float c)
  • void vertex(float x, float y, float z)
  • void vertex(float x, float y, float z, float tx, float ty)
  • void texture(PImage img)
  • void background(float c)
  • int color(int r, int g, int b, int a)
