Go on, it's not that complicated with Java3D. Work your way
through the SUN provided tutorial at
http://java.sun.com/products/java-media/3D/collateral/.
And have a look at
Does Sun or anyone else provide commercial support for Java 3D? Or will
it always be "unsupported freeware"?

I am not new java, but new to Java 3D...as well as 3D

It's just an array of floats from 0.0f to 1.0f, same length as the
'quats' array parameter. Consider them 'keys' for the quats array.

only have to do it once -- it can't be impossible. and who cares if it's

Hi !
I'm a newbie in Java3D.
I'm develloping an application which loads a wrl file and we can
interact with the object by the mouse.
My problem is that I would like to center any vrml object in my window
and view it entirely after loading.
Any source code and easy examples will be very appreciate

I'd like to chime in also supporting "keep it simple".
Yes, access to the low level stuff is great for when we need it.
However the standard problem that occurs with Java is failure to
document and explain when, where and how to use which features. A
*major* part of keeping it simple is to docum
Hi, John ,
You have to install GL4Java to run the demos.
There are several DLLs to install.
There is a installer avail in jausoft site. you just need to d/l it, and it
will download the remaining files automatically.
GL4Java is powerfull. O good video card (ATI, Nvidia) with OpenGL helps a
lot ;)

Well you have to get rid of the state-based thinking and start thinking in
higher levels and in graphs. Basically it shouldn't be so hard, but you
could miss some functionality you have

I don't think thats completely true. Exposing the low level API in a controlled
manner need not make the rest of the API more tied in. The user of Java 3D
takes the choice of using the low level API, and if they're careful they
can then replace they're low level access of the API with the final
But
the more you expose the low level API, the more locked in you are to one way of
doing things. Encapsulate and only show the higher level seems more
sensible.

Thats handy, I was just typing a mail in agreement with that.
You could relate it to the extensions mechanism in OpenGL as it stands. It
means as new features come out the time it takes to abstract the new functionality
in the API doesn't stop people using it. In Java 3D this would be the miss
well, I don't see a reason why exposing parts of the low level API should
make Java3D harder to use.
after all, you don't HAVE TO use it.
If you're content with the high level API - fine !

Hi Roy,
I have thought about a similiar problem and I'm wondering
if one solution is to move the earth surface a short distance
away from the water sphere.
I know this means you have to traverse and modify all your
coordinates for the earth surface, but this will not take that
much time even wit
I agree absolutely with this opinion. I have been trying for more than 20 years of
programing to follow this idea but I don't understand why is so dificult to explain
and to do.
I think that the best way to expand the use of Java3d is to keep it simple to use for
everyone and not to transform
