  [SOLVED] Updating Textures with Texture2D  (Read 1456 times)

There is nothing common about common sense

« Posted 2006-10-17 12:44:19 »

How does one update a texture once the texture already has been set.

For instance, say we have this:
Shape3d shape;
ImageComponent ic;
Texture2D texture;
BufferedImage bImage;

bImage = new BufferedImage(...);
ic = new ImageComponent(...,bImage);
texture = new Texture2D(...);
shape = magicShapeCreator(...);  // say this function handles creating the shape with the right Appearance, normals, and texture coordinates

OK. so at this point the shape is added to the scene and displays the textuer properly.

Now what i want to do is to be able to update the texture.
I've tried so far to just update bImage ( but that doesn't update whats being drawn on the screne).
(for instance bImage.createGraphics().drawString(a new message poped",0,100);

Any thoughts?

I just made up a small test and it looks like you have to do the following.

For the ImageComponent2D - set the ALLOW_IMAGE_WRITE capability.

Then any time you update the BufferedImage, you must re-set it in the ImageComponent2D.

For instance:
// now reset the image
