Hi
I've still problems with my ZBuffer. I have extended
Canvas3D with my own subclass. But everytime I
call readRaster and get the DepthComponent it
contains only zeros. It doesn't matter if I call
it after postRender() or postSwap(). Here's my
source
public class ExtCanvas3D extends Canvas3D {
private Raster zRaster;
private DepthComponentFloat zDepth;
private float[] bufferZ = new float[640*480];
private ImageComponent2D imageComp;
public ExtCanvas3D(java.awt.GraphicsConfiguration
graphicsConfiguration) {
super(graphicsConfiguration);
zRaster = new Raster();
zDepth = new DepthComponentFloat(640,480);
zRaster.setDepthComponent(zDepth);
ImageComponent2D imageComp =
new ImageComponent2D(ImageComponent2D.FORMAT_RGB,
new BufferedImage(640, 480, BufferedImage.TYPE_INT_BGR));
zRaster.setImage(imageComp);
}
public ExtCanvas3D(java.awt.GraphicsConfiguration graphicsConfiguration,
boolean offScreen) {
super(graphicsConfiguration,offScreen);
}
public void postRender() {
this.getGraphicsContext3D().readRaster(zRaster);
zDepth.getDepthData(bufferZ);
for (int y=0; y<480; y++)
for (int x=0; x<640; x++)
System.out.println(bufferZ[x+y*640]);
}
}
