How to you turn on OPengl smoothing ?
Apr 19th, 2010, 9:12am  
I use the following

[code]
import processing.opengl.*;
void setup(){
size(200,200,OPENGL);
noSmooth();
HINT(DISABLE_OPENGL_2X_SMOOTH);
HINT(ENABLE_OPENGL_4X_SMOOTH);




}

[code]

.. to no affect. Smoothing works great with P3D

What am I doing wrong ?

smooth() should work fine in OpenGL, as should the generic hints for antialias
There are some special things if your using the Fullscreen library.

Some of the more advanced commands would look something like this...
gl.glHint (gl.GL_LINE_SMOOTH_HINT, gl.GL_NICEST);
gl.glHint (gl.GL_POINT_SMOOTH_HINT, gl.GL_NICEST);

gl.glEnable(gl.GL_POINT_SMOOTH);
gl.glDisable(gl.GL_POINT_SMOOTH);

gl.glEnable(gl.GL_LINE_SMOOTH);
gl.glDisable(gl.GL_LINE_SMOOTH);

Thanks jeffg.

Can you post some code that I can try this snippet and see how it works ?

This certainly get's into more direct OpenGL and the simplicity of direct Processing code, but here it is...
Code:
import processing.opengl.*;
import javax.media.opengl.GL;
GL gl;
PGraphicsOpenGL pgl;

void setup(){
  size(200,200,OPENGL);
  hint(DISABLE_OPENGL_2X_SMOOTH);
  pgl = (PGraphicsOpenGL) g;
  gl = pgl.gl;
  gl.glHint (gl.GL_LINE_SMOOTH_HINT, gl.GL_NICEST);
}

void draw() {
  pgl.beginGL();
  gl.glEnable (gl.GL_LINE_SMOOTH);
  gl.glLineWidth(4.0);
  gl.glBegin(gl.GL_LINES);
  gl.glColor3f(0,0,0);
  gl.glVertex2f(0,0);
  gl.glColor3f(0,0,1);
  gl.glVertex2f(width,height);
  gl.glEnd();
  gl.glDisable (gl.GL_LINE_SMOOTH);
  pgl.endGL();
}
