"PGraphicsOpenGL" was not found
May 12th, 2007, 5:02pm  
Hi All,

I´ve been trying this simple code:

import javax.media.opengl.*;
import javax.media.opengl.glu.*;

GL gl;
GLU glu;

void setup()
{
 gl=((PGraphicsOpenGL)g).gl;
 glu=((PGraphicsOpenGL)g).glu;
}  

void draw()
{
}

and I´ve got this error:

C:/DOCUME~1/q/CONFIG~1/Temp/build62717.tmp/Temporary_8075_376.java:9:8:9:22: Semantic Error: Type "PGraphicsOpenGL" was not found.

C:/DOCUME~1/q/CONFIG~1/Temp/build62717.tmp/Temporary_8075_376.java:10:9:10:23: Semantic Error: Type "PGraphicsOpenGL" was not found.

I read the OpenGL part of the forum and only found one subject in this line, but not the same.

Thank you.

You need to import processing.opengl.*; as well as the javax.media.opengl ones.

John, Thank you for the answer. I added the new line and the code seems like:
---------------------------------------
import processing.opengl.*;
import javax.media.opengl.*;
import javax.media.opengl.glu.*;
GL gl;
GLU glu;
void setup()
{
 gl=((PGraphicsOpenGL)g).gl;
 glu=((PGraphicsOpenGL)g).glu;
}
void draw()
{}
--------------------------------------
Now I have this error:

java.lang.ClassCastException: processing.core.PGraphicsJava2D cannot be cast to processing.opengl.PGraphicsOpenGL

I tried this too:

---------------------------------
import processing.opengl.*;
import javax.media.opengl.*;
import javax.media.opengl.glu.*;

GL gl;
GLU glu;

void setup()
{
 size(200,200, OPENGL);
 gl=((PGraphicsOpenGL)g).gl;
 glu=((PGraphicsOpenGL)g).glu;
}
--------------------------------

but the error now is...

java.lang.UnsatisfiedLinkError: C:\Archivos de programa\Java\jre1.6.0\bin\jogl.dll: Can't find dependent libraries
