Hi i want to write additional textual Information over
the 3D Scene.
I tried it with a raster. In front of the complete
Scene. I tried to make the black content to be
transparent. But the black content in not transparent.
I tried it with the following.
Raster raster = new Raster();
raster.setPosition(new Point3f(0,0,-1));
raster.setOffset(10,10);
raster.setSize(100,100);
raster.setType(Raster.RASTER_COLOR);
raster.setCapability(Raster.ALLOW_IMAGE_WRITE);
BufferedImage image2D = new
BufferedImage(100,100,BufferedImage.TYPE_4BYTE_ABGR);
Graphics2D gr2D = image2D.createGraphics();
gr2D.setColor(Color.red);
gr2D.fillOval(10,10,100,100);
WritableRaster writeRaster =
image2D.getAlphaRaster();
int [] array = new int[1];
array[0] = 0;
for (int x = 0; x < 100 ; x++) {
for (int y = 0; y < 100 ; y++) {
if (image2D.getRGB(x,y) == 0) {
writeRaster.setPixel(x,y,array);
}
}
}
raster.setImage(new
ImageComponent2D(ImageComponent2D.FORMAT_RGBA,image2D));
objRoot.addChild(new Shape3D(raster));
Do you have any solution hints?
CU Sebastian
