I've put some timing code in my applet. It may be useful to do a comparison
between 1.5 and 1.6 with the D3D acceleration on your own machine.
What you will see in the console window is --
PanCyl v0.3.2_D3DTest
Interp Time = 841ms
Paint Time(640, 360) = 50ms
---
Interp Time = 591ms
Paint Time(640, 360) = 30ms
---
Interp Time = 611ms
Paint Time(640, 360) = 30ms
---
What you are looking at is the time to interpolate a 640x360 image (my own
bicubic interpolator -- it's slow) and then the time to paint that 640x360
image in a Canvas.
Here's the rendering method that is in MyCanvas. I only use paint() for system
events. mis is a MemoryImageSource; bs is the BufferStrategy; bg is the
BufferStrategy Graphics
//this is what is timed
t1 = System.currentTimeMillis();
System.err.println("Interp Time = " + (t1 - t0) + "ms");
t2 = System.currentTimeMillis();
canvas.newPixels();
t3 = System.currentTimeMillis();
System.err.println("Paint Time(" + canvasW + ", " + canvasH + ") = " + (t3 -
t2) + "ms");
System.err.println("---\n");
public void newPixels()
{
try
{
if(!this.isShowing())return;
do {
do {
bg = (Graphics2D)bs.getDrawGraphics();
mis.newPixels(0,0,thisW,thisH,true);
bg.drawImage(canvasImage, 0, 0, thisW, thisH, this);
if(DRAWATT)
drawAttribution(); // ignore this
bg.dispose();
} while (bs.contentsRestored());
bs.show();
} while (bs.contentsLost());
}
catch (Exception ie)
{
ie.printStackTrace();
}
}
