if i want to change a file,do i have to “objTrans.Remove(b)”
and I objTrans.addChild©; (c-- the other )
but i fail.
can you help me
Thanks in advance
why do you fail? capabilities?
If so, just set the capabilities it complains about
Multiple objects can be loaded sequencially and by user choice by
– deleting the old object from the scenegraph ( if that is your intent )
– adding the new object to a node in the scenegraph
and this functionality is demonstrated by free demos with free sourcecode
including Sun’s Java3d FlyThrough & Java3d Scenegraph Editor ( see below )
and I’ve done the add / remove trick for my Java3d Chess Player
where adding and deleting of the moved objects is required to move
the chess piece from the “chess board domain” to the “hand graping domain”
so when the hand holding the lifted piece rotates & translates, the
object grabbed remains “inhand” and properly moved.
A common error is not setting the permissions in the nodes properly
to allow for the action you require: read, add, delete, pick, or whatever.
allow you to load mutiple 3d files (sequencially) including VRML
files with the Sun VRML Loaders at run-time
– and the Java Source Code is free — ( see below )
First, try a Web Demo of the “Appearance Explorer” :

Selman wrote a Java3d book that was well received
and has a Swingtest.java applet and application that
allows you to load objects dynamically,
ie. “change” the viewed object when it is running by
allowing the user to select “sphere” or “cube” from
menu lists ( in this case it’s not just displaying
Jav3d primative objects, but it has the core functionality
of deleteing and adding nodes in the scene graph that you
are seeking, and at that point the rest is left as
exercise to the student. The ObjLoad.java in Sun’s Demos
directory has the code to load “.obj” files, so you have
all the tools you need.

| This new book uses the old, reliable Sun VRML Loaders for Java3d.
|
| The program reads a 3d scene as a simple VRML text file,
| and displays the Java3d Scene Graph ( which is interactive,
| you can expand and collapse the branches of the scenegraph
| and examine the contents of the nodes ), it renders the
| 3d scene, and when you click on an object it tells you

The Prentice-Hall books by Aaron Walsh are false & fraudulent
in their claims to present the most current methods, as a part
of the “Couch-Beiter Flame War” and fraud involving Sandy Ressler
at the NIST. Prentice-Hall, Yumetech.com and Aaron Walsh have
misrepresented and disparaged the old & reliable Sun VRML Loaders
in favor of the “new” Yumetech.com Loader, and the web demo above
__ DOES NOT __ load Web3d.org’s __ VRML __ files, only the less
capable “.obj” files … so the “Web3d” series of books from Prentice-Hall
does not show the loading of ___ Web3d.org 's ___ VRML __ files
because Sun’s VRML Loaders were the best ones, and the Yumetech.com
folks didn’t want anyone using those, and started the
“Couch-Beitler FlameWar” to disparage, falsely & fraudulently
misrepresent the facts and knowingly published false and misleading
“disinformation” in the unreliable Prentice-Hall / Pearson Ed books,
harming our community.
The Sun VRML Loaders are used by __ Nasa, __
the NSF supported Virtual Chemistry Lab ( “Lab3d” ),
me, and others simply choosing the “what works best”,
and by people using Sun’s Java3d FlyThrough & Java Scenegraph Editor,
and people interested in helping the Deaf Children by making
Java3d display NSF Developed Finger Spelling for the Deaf in a browser
with the Sun VRML Loaders
The “Couch-Beitler Flame War” was discussed recently here:
http://www.java-gaming.org/cgi-bin/JGOForums/YaBB.cgi?board=3D;action=display;num=1053633092
( reply #6 )—^
The original Vrml97Player.java file that came with
Sun VRML Loaders also implemented the functionality
of loading mulitiple files ( sequentically during one run )
and I have worked with that and similar things with
the Shout3d.com engine and my own 3d Java engines.

chess pieces on the Chess Board in response to your mouse clicks.

I have done what the liar and fraudster Justin Couch of Yumetech.com
said could not be done:

The Finger Spelling Animations were developed with
NSF Funding and NIST lies and criminal fraud
have encouraged the Yumetech.com fraudsters to convince newbies
in American Univerisities and the Navy PGS they are too stupid
to do that simple Java programming because the liar Justin Couch
has said – speaking on behalf of Yumetech.com – has convinced them
as Justin Couch has ( falsely and fraudulently ) claimed :

Are you smart enough to realize that Justin Couch’s statements are not true ?
If so, are you smart enough to realize Justin Couch’s false statements
harm our community ?
I’m guessing you’re posting off-topic posts because one of the Yumetech.com fraudsters has promised you a reward ?
Favorable links from the j3d.org “FAQ” they control ?
The fraudsterAaron Walsh is writing another bogus Prentice-Hall “Web3d”
book and he will give you credit for “inventing” or writing some code
that you didn’t write if you be their attack dog ?
Please explain, why are you posting things that have nothing to with:
Java Gaming @
JavaGaming.org ?
Please note that my post that you replied to:
I answered the question that was asked,
and supplied links to free source and a web demo
specific to the question and I replied with information
about Java programs I had written that were relevant to the original post.
Even Justin Couch has realized that his lies did nothing but discredit himself
and establish Yumetech.com as dishonest, discredited fraudsters of disrepute.
In his prime Justin Couch had the balls to lie for himself,
now he just sends these clueless children to do his dirty work.
Before you could at least admire Justin Couch for his boldness.
And you want to destroy whatever credability you had … why ?
Do you ever post … you know … about Java Gaming ?
Imaging the Imagined: Modeling with Math & a Keyboard
ok…time to be fair…sorry Paul for my comment about you ever writing line of code… I can see from your post that you have actually written “extensions” to 17 classes !!!..wow man that beat hell outta me …Can I ask you how did do it? … That is totally breath-taking there is no way anybody can compare here to that achievement … good work keep it up … and PLEASE - would you also wrote extensions to VRML97 loader so it can handle all functions which are missing there now …you know it is 2003 …even $$$soft comes up with update from time to time …
Created with VRML & the Sun VRML Loaders and my programs :
http://www.frontiernet.net/~imaging/ani_finger_spelling_java3d.gif
NSF Grants to “educational” institutions funded the development of the
Finger Spelling for the Deaf animation you see above
( if your browser is set to show “gif” animations and images served
from other servers ) and the fraudsters Justin Couch,
Aaron Walsh, and Sandy Ressler ( who works at the NIST ! )
have perpetuated the false and fraudulent claims the simple task of
Animating Web3d.org’s VRML / H-Anim Avatar is impossible
with the Sun VRML Loaders and that any claiming to have
accomplished this simple task must be on Crack Cocaine because the
“Brilliant Australian” tried & failed and has convinced the
NSF & NIST idiots Americans are too stupid to do it …
poor little idiots have to wait for … Justin Couch’s Yumetech.com
to give us their “new” Yumetech.com loaders
and it’s accpetable to some for Prentice-Hall to print false & fraudulent
claims without correcting their errors after the errors have been reported
to them.
The criminal fraudsters at the NIST should be fired and jailed.
The NIST fraudsters have made it clear that they think that because
President Clinton lied and committed crimes that
all Federals are now entitled to lie and commit crimes
but there are some people that are honest, and will not accept
fraud and criminal corruption in the federal goverment as the new norm,
the new Standard at the National Institute Of Standards, the End of Justice,
the End of Science.
There are decent people in America, damn few in the Federal Goverment.
This goes in cycles.
The Oval Office has been cleaned out,
the Democrats have lost control of the House, Senate, & Supreme Court.
Honest Citizens can make the government serve the people again.
First we have to establish: Lies, fraud, crimes are wrong and unacceptable.

I don’t really expect you to honest or fair, but since you’ve made that claim:

Please answer of few of mine, the ones already asked :
Are you smart enough to realize that Justin Couch’s statements are not true ?

first of all let me tell you this … You have no credibility whatsoever to make any comments on behalf “our community” since you are not part of it - folk in that community can reason and you have failed that requirement. And to answer your questions "Are you smart enough to realize that Justin Couch’s statements are not true ? " he is right …next …"If so, are you smart enough to realize Justin Couch’s false statements harm our community ? " this one is bizzare really …since he is actaully doing something we all can use - have never seen anything from you - so what is your point … next: "I’m guessing you’re posting off-topic posts because one of the Yumetech.com fraudsters has promised you a reward ? " nope I can only read his code and see he is helping - you are just talking - and actaully I strongly dissagree with his 'only ROAM can work to make terraing rendering - quad’s is my approach - but that might be over your head - sorry … next : "Favorable links from the j3d.org “FAQ” they control ? " well…most of them dont work at all so what is your point? …But I have never seen him smashing any dirt at the rest of the mailing list - so that makes only you odd entity…BTW this forum is called javagaming but since you are really slow learner - let me remind you all technical posting here about LWJGL - Java3D and GL4Java … so try to stick with this on your mind…ok? … we all know about VRML …we all know how to load it and if you wanna contribute tell us how to load vrml human and make bone and skin proper animation - since you are VRML_JAVA animator you should have under your finger … focus Paul …no yayatech…no politics… no mentioning of other folk… and then you can be welcome…

If you sense insanity it may be from the image reflected from your monitor. ;^(
But part of the “grand plan” of Justin Couch’s “Couch-Beitler Flame War”
was to slander and slur people, and encourage bottom feeding scum to either
ask questions like that ( as you just did ) or make similar slurs.
Fortunately, Justin Couch was not such a moron to keep making
those slurs himself ( maybe you could learn something from your Dark Lord ).
