Clearing BufferedImage?
Hi, I have a 3D app that displays a buffered image regularly. At first I wrote to the same bufferedimage every display time, which resulted in the previous image not being cleared. My solution was to create a new buffered image every time the display function is called like so:
zCol =new BufferedImage(screenX, screenY,BufferedImage.TYPE_INT_ARGB);
Now this works, but hogs roughly 70% of system resources, compared to 25% odd whenusing the previous example. My question is can a buffered image be cleared without re creating it? I have looked at BufferedImage's methods and found flush(), but this does not clear the image as I thought it might.
Thanks in advance :)

That doesn't work, I assume because the BufferedImage still contains all the old images that have been displayed using it, so it just paints that.

It's not a 3D API unfortunately, I have to write everything myself (to gain a 'better understanding' of 3D)
I am using a buffered image for zBuffering which is performed every time the object is rotated (about 20 times a second) with the zBuffer results being written to this buffered image. I then display the buffered image like so:
graphicsContext.drawImage(image, 0, 0, this);
I would have thought there would be a simple clear function for buffered image that I could call before each zBuffering is done.
