Opengl syntax
May 27th, 2010, 7:41am  
Can someone post the processing syntax for the following opengl ?

glClearColor (0.0, 0.0, 0.0, 0.0);
 glClear (GL_COLOR_BUFFER_BIT);
 glColor3f (1.0, 1.0, 1.0);
 glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
 glBegin(GL_POLYGON);
    glVertex3f (0.25, 0.25, 0.0);
    glVertex3f (0.75, 0.25, 0.0);
    glVertex3f (0.75, 0.75, 0.0);
    glVertex3f (0.25, 0.75, 0.0);
 glEnd();
 glFlush();

http://processing.org/reference/libraries/opengl/index.html

basically

 PGraphicsOpenGL pgl = (PGraphicsOpenGL) g;  // g may change
 GL gl = pgl.beginGL();  // always use the GL object returned by beginGL
 
then gl.glWhatever(); for methods and GL.GL_WHATEVER for constants.

then
 pgl.endGL();
