hi
Have a look at the following code. It creates a subclass of
Canvas3D and overrides the postSwap() method. The code was taken
from a previous posting - I think it was from the Vrml97Player.
The FrameRateListener was inserted by myself and provides a _simple_
way of registering a listener.
import javax.media.j3d.*;
public class AdvCanvas3D extends Canvas3D
{
public FrameRateListener fpsListener;
long frameCount = 0;
double lastTime = System.currentTimeMillis();
public AdvCanvas3D(java.awt.GraphicsConfiguration gcon)
{ super(gcon);
}
public void postSwap()
{ frameCount++;
if( (System.currentTimeMillis () - lastTime) >= 1000d)
{ double interval = (System.currentTimeMillis () -
lastTime)/1000d;
double fps = frameCount / interval;
// Write your own code instead of fpsListener.update(..)
// if you like!
fpsListener.update(fps, frameCount, interval);
lastTime = System.currentTimeMillis ();
frameCount = 0;
}
}
}
