From ea819ff768d507c37a981c1ab0bdc0cad32c6a87 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 23 Apr 2011 06:20:45 +0200 Subject: New FPSCounter, impl. by GLWindow and GLAnimatorControl (fps perf related API change) - Don't fetch System.currentTimeMillis() by default and for every frame (performance) - Default behavior is FPSCounter switched off - Enable by frame interval, ie measure each 60 frames. - FPSCounterImpl is default impl. used by impl. FPSCounter class (reduce code/redundancy) - Might be promoted to GLAutoDrawable ?! --- .../classes/com/jogamp/opengl/util/Animator.java | 14 ++--- .../com/jogamp/opengl/util/AnimatorBase.java | 61 ++++++++++++++-------- .../com/jogamp/opengl/util/FPSAnimator.java | 2 +- 3 files changed, 45 insertions(+), 32 deletions(-) (limited to 'src/jogl/classes/com') diff --git a/src/jogl/classes/com/jogamp/opengl/util/Animator.java b/src/jogl/classes/com/jogamp/opengl/util/Animator.java index 4fbd0e478..e7fbc4d58 100644 --- a/src/jogl/classes/com/jogamp/opengl/util/Animator.java +++ b/src/jogl/classes/com/jogamp/opengl/util/Animator.java @@ -125,7 +125,7 @@ public class Animator extends AnimatorBase { class MainLoop implements Runnable { public String toString() { - return "[started "+isStartedImpl()+", animating "+isAnimatingImpl()+", paused "+isPausedImpl()+", frames "+getTotalFrames()+", drawable "+drawables.size()+"]";
