Questions about using Java 3D

Hi everyone (newbie here),

I'd like to develop my skills to become a professional java developer.

I was wondering about your opinion regarding the Java 3d API. Is it
popular?

>From my google searches it looks like Java3d is most popular in the

mobile
device realm. Everywhere else it appears quiet. So for instance I
wanted to
build a 3d applet for my website (to build my portfolio). Do you think
this is
wise? Or are there better alternatives?

Thanks for any advise,

Dennis.

The short answer is no, not really.

I don't think that your two questions provide mutually exclusive
answers. If you're building a 3d app for your website, java3d is almost
certainly a very good choice, particularly for a lone developer - it's
pretty easy to get into, and it does the simple stuff well.

As to whether there are better alternatives, there probably are
alternatives that are better in some ways than java3d, though I don't
know of any.

I thought Java3d is an additional install apart from the JVM? doesn't
that mean that probably most (regular) users won't be able to see
applets with java 3d content?

Thanks for the responses.

Here are some further questions that touches on Mattias' questions.

The installation of JDK 1.6 contains a demos. If you look under
applets you'll find a Molecule Viewer applet. This applet is 3D yet
the source doesn't include the Java3D API?
So it seems I can see applets with 3d content. So based on this applet
... what is the point for the Java3D API? Am I confusing something?

Another thing is that the Java3D tutorial is terribly old. So the
reason I asked was whether learning it was worth it if it was going to
be deprecated in the forseeable future, etc.

Thanks again.
Dennis.

Take a look at the Wireframe demo too. Many of these demos were include
in the JDK 1.1 around 1997.
Looking at the source code of Java3D,
https://j3d-core.dev.java.net/, i guess that they had so much fun
writing those demos that they decided to create Java3D out of them.

All 3D API's are based on 2D drawing no matter wich langage you use
( OpenGL, DirectX, C++, etc...). By the way, Java3D is written in Java,
of course. The point of any API is that you don't have to reinvent
the wheel every time you start a new project!

I do not think so!!!!

Thanks everybody for all your responses.

I think I'll have to roll my own if I want it installed in an applet.

Matthias, you are completely correct. Apologies.
