Hello,
I have a question concerning java 3d 1.2.1 VS java 3d 1.3. I have not been
able to upgrade to 1.3 until just recently. The problem
I had was the sphere I was texture mapping with just a jpeg image would
show up fine in 1.2.1 and would show up white in 1.3. The code fix was the

Hi all,
First of all sorry, for reposting this message.
I have a basic question for you. What exactly is
harware texture mapping. why texture mapping depends
on hardware and what is the role the hardware in the
concept of texture mapping?
Thanks in advance,
Sagar.
Group:
I have a .jpg of the earth that I am texture mapping to a sphere. This is
an image off of the internet, and is of poor quality. Whenever I zoom in
closer, it is really pixelated. Is there anyway to solve this, or do I need
a higher-res image. I need this earth to be highly detailed
imensions on-the-fly.

Sam,
No you are right the filters do not alter the shape in any way. They work
by either using point sampling of neighbouring texels and using that colour,
or by interpolating among neighbouring texels, depending on which mode you
choose.

That means the observer.checkimage has returned ImageObserver.ERROR
