Newbie: Java applet to display and rotate 3D surface described in VRML
Terry Orchard
I want to display surface shapes on a web page and let the user rotate
them and zoom in and out. Here's an example of the kind of thing I
want to do: http://mathworld.wolfram.com/Paraboloid.html. This example
is typical of the simple shapes I will be doing, and has just the
interaction I am looking for. However, the example uses
LiveGraphics3D, which is a Java applet that displays data from
Mathematica. I will be generating my data in my own C++ program, so
LiveGraphics3D does me no good.
In looking for alternative solutions, I stumbled across vrml. It looks
to be pretty easy to generate vrml for the surface shapes, so my
thought is to find a java applet that will display the vrml, and
handle the user interaction. I would prefer the applet over a plug-in
or a separate vrml browser because my users are unlikely to have a
vrml plug-in or browser installed.
Does such a thing exist? Is there a better approach to what I want to
do? Thanks for any help.

There is an applet available from Blaxxun. The url is:
http://developer.blaxxun.com/download/index.html
I have never tried embedding the applet myself, but I have seen it on a
couple of sites and it seems to work well, and the download time is
remarkably short.
Cheers,

Thanks Ian, Blaxxun looks like just what I want.
However, at €499 it's pretty expensive for a personal site. Are there
any alternatives?

posted to 3 groups when my original post was to only one, but I've
removed the cross-posting, since it tends to annoy people.
I had come across your site in my searching, as well as similar posts
from you in the past. But I'm not sure how this applies. Everything I
saw in the links you provided seems to be aimed at writing custom Java
applets for doing the "animation". I was hoping to avoid writing my
own applet, and instead use a "standard" applet that I could feed data
into. LiveGraphics3D works this way, but it uses an input data format
that is specific to Mathematica (and pretty much undocumented).
Blaxxun3D works this was as well, but is pretty expensive for what I
want to do.
Do you know of any other options? Or am I missing something in the
links you provided?
Thanks,

Blaxxun3d and Shout3d were "free with banner"
and available without the banner for a small fee,
the price you mentioned was a lot higher than
I thought, are you sure that was right ?
The animation is the fun part, that's what
makes it more interesting for lots of us.
I know you posted to just one group,
but it's about Math, Java, & VRML and
someone with the perfect solution may
be in the other group, and not the VRML
group.
Some of the objections to cross postings
are for less then honorable reasons.
Many in the VRML group are fanatics not of
VRML but of a particular VRML browser Producer:
Cortona Fanatics attacking Cosmo Fantatics,
Contact Fanatics attacking Cortona Fanatics,
and contented Cosmo users happily using the
most standards compliant browser that runs on
Windows, SGI Irix, and the Macintosh. ;^)
And some colaborate with the monopolist and
attack solutions that are faithfull to
__ the Promise of VRML __ and are
portable to platforms beyond the desktop
and beyond the control of the overpriced
OS that the Feds found to be
violating US laws, hurting competition,
hurting consumers, and stiffling innovation.
Some people in the VRML group attacked
the quality of "my Java3d" even though
I was showing models faithfully and correctly
rendered that were created by NIST staffers
including Sandy Ressler and US Navy PGS
Don Brutzman ( both Web3d.org staffers too ).
There is a synergy, a common interest,
common problems and common solutions
amoung those of us using VRML, Java and Math.
Some claiming to be annoyed only wish to control.
Anyone honestly interested in VRML, Java, or Math
wouldn't object a posting about VRML, Java, or Math.
I do 3d with a keyboard, VRML, Java and Math.

This is pretty close to what I want, actually. The only thing I would
like is color.
But I see nowhere on your site to download applets or code, nor
anything that says that I am free to use it. Is it available on the
web?

I'm afraid this site is seriously out of date. It does have hundreds
of links, but most of them are broken. I saw nothing newer than about
3 years ago, and most of it dates from the mid 90s. I tried many of
the Java links, but found nothing appropriate (mostly dead links,
links to advertising pages that have taken over the domain, etc.). I
finally gave up in frustration.
>Blaxxun3d and Shout3d were "free with banner"

No, I'm not sure. The blaxxun site says "Download and test usage of
blaxxun3D is free; using it on your webpage requires a license fee."
The purchase page shows blaxxun3D Evaluation "An unlicensed free
version with nag-screen" is free, and the domain license is €499. That
looks to me like you have to purchase it to use on a webpage, but I'd
be delighted to be wrong.
Shout3d does say they have a free, fully functional, but "with
branding" version. But I found no place on their site
(http://www.eyematic.com/products_shout3d.html) to download it. There
is no download section on their site at all, they just point you to
resellers.
Thanks for your help.

You could use FastScript3D to create a java3d applet do to what you
want. There are simple commnads to do the manipulation of the object
once it is loaded. And, there are many examples on how to load various
file formats such as VRML.

And that's the problem. As I said in my original post, I prefer the
applet over a plug-in or a separate vrml browser because my users are
unlikely to have a vrml plug-in or browser installed. Java3D falls
into the category of plug-in, at this time.
Thanks for the suggestion.

Your concerns are well founded. It puts a requirement on the user
to have to set up Java and Java3D, and get them working properly
in the browser. That is really the limiting factor like you said.
There is recent encouraging news on the ruling that Microsoft
will need to bundle Java technology in the near future. That might
alleviate the problem. Once you get the Java3D setup in place,
FastScript3D makes the technology pretty easy to use via HTML and
JavaScript.

you don't have to write the applet yourself :-).
I have used Anfy3D, Spazz3D was the authoring tool for the VRML side of it.
My understanding is that the partnership was dissolved because Anfy did not
want to make changes that Spazz requested.
Shout3D is good and is now integrated with Spazz3D, I have some examples...

It does have a little nag logo, and you have to pay cash to get it removed.
I have also scoured their web site and can not find the download any more
:-(.
(but I have the code if you are real desperate we can figure out how to get
it to you). Shout tries to do more, so the download is bigger/longer.
Blaxxun3D works well also, and the nag logo is not that bad. They have
better instructions on the HTML to applet interaction (buttons & color
changes, etc.)
The thing I don't like about the applet approach is that you have to
download the code everytime. This may be OK for the casual user. Sure, it is
a pain to download a VRML plug-in once, but with Java applets you get 1,000
little deaths instead of one big one. The VRML plug-ins have been trimmed in
size a lot since they have dropped internal support for VRML1.0 (and other
optimization) and many folks have adapted to a higher bandwidth way of life
:-)

Infortunately, your site doesn't work for me. I just get a gray box
where the Jet applet should be. If I hold my cursor over the gray box,
the status bar says "load: class ViewerInputApplet not found". I'm
running IE 5 on Win2K.
However, when I go to the parallelgraphics site, the Jet applet works
fine, I see the scene and animation.

It's not the download that hurts, it's the install. Users will not
install something just to view a web site, they will quickly go
elsewhere. Installing a plug-in, no matter how small, takes time, you
don't know what it's going to break, you don't know what security risk
you are taking. The folks I want to bring to my page don't have any
idea what vrml is, and are not going to install a vrml browser.

Hummm. It works for me (these are the kind of errors I hate), the first one
"jet.htm" was an earlier try at it and does not "autoload", you must hit the
load scene link to see the box turning. It is sad that you can not see it
because I made this parabola model to show that we could have something
similar to the original page you posted. (Maybe if you try again it will
magically appear; don't laugh, it works that way sometimes). There may be a
newer g3d.jar file, I will get that and put it on my site.
http://philliphansel.com/jet3test.htm
I would have liked to have contours on it, but Jet does not support
textures. I had difficulties at first because I forgot that Jet does not
support extrusions, once I converted them to IFS it showed up. Also,
although the documentation says it supports the background node, it is
evidently a limited one (maybe only one color?) because mine did not show
up.

Ok, I agree that this is true for the unwashed masses. Only diehards have
more than 4 vrml plug-ins. "Know thy audience" is key to retaining them.

Yes, I had noticed that, and refresh did not help.

Now this works perfectly. Autoloads and everything. Thanks for the
great example.
And now I go back and the original 2 pages are working, too. So it
probably was the old jar file.

Thanks very much for the suggestion, and the demo. I will play with

Jet product, it doesn't provide it for download, and it does not say
it is free to use. It doesn't show on the price list, either. Do you
have any information about the licensing. And where did you find the
newer jar file to download?
Thanks

- can read & write VRML
- limited support for color
- can run in a web page or stand-alone as an application
- can view any multiple objects with a button click
- can read local files when run as application
- has support for Nurbs surfaces ( non-standard )
- can rotate object with mouse drags or 3 dial controls
