can you manupulate different parts of a loded object eg load a character and rotate its limbs with my own interpolation code

Helo guys.

Need some help with loading and animating a character. Maybe im going about it all wrong but here is what i have so far.

Created a humanoid character in 3dmax  added bones ( head to toe ) exported as obj / ase (i have both files)
created a chracter class like the tankase example but when i run i get athis error:

Exception in thread "main" java.lang.IllegalArgumentException: This Node already has a parent.
        at org.xith3d.scenegraph.GroupNode.addChild(GroupNode.java:142)

the error id from this line

 Bone_Head.addChild((Node)nodes.get("Bone_Head"));

anyhelp will be appreciated. Is there anywhere i can get TUTORIAL on loading and controling individual parts of a model?

i love you guys................... thats was it.

Now  i have to figure out why its drawing only one ball

thnx!

now i get only one sphere then the window closes with these errors:

heres the code im trying to run:
         gl.glColor3f(1.0f,1.0f,1.0f);

         quadric = new GLUquadric();
         glu.gluQuadricDrawStyle(quadric,glu.GLU_FILL);
           //gl.glBegin(GL.GL_POINTS);

           for(int j = 0,m = 0; j < ( balls.length/2 ); j+=2, m++){
             if(!gbs[m].getPick()){//if golfball has not been picked render it
               //gl.glVertex3f(gbs[m].Golf_Ball_XCor, gbs[m].Golf_Ball_YCor, 0.0f);
               gl.glTranslatef(gbs[m].Golf_Ball_XCor, gbs[m].Golf_Ball_YCor, 0.0f);
               glu.gluSphere(quadric, (double) gbs[m].radius, 20, 40);
               System.out.println(gbs[m].Golf_Ball_XCor+" "+ gbs[m].Golf_Ball_YCor);
             }
           }
         //gl.glEnd();

people how exactly do impliment the glutsolidsphere() i keep getting a null pointer error.

has anyone tried art of illusion? how compatible is it with jogl? will i need a loader for my models?

java cool dude
it's possible that  the shadow from your dinosuar is falling on the wrong side of the ball. Check your normals, you might have to renormalize them.

have you ever found your self doing something as dumb as trying to run an application without a "main" thanks aNT man, it runs just fine now.   (i was losing it there for a while)

thanks alot aNt but i understand all that. i have run several of my java programs as well as tutorials but im trying to run the jogl triangle program and i am not sure how to configure the run tab:

package jogls;

}

any idea?

when you click run  the properties dialog box opens up with the run tab selected. then what next

so if i get intelij or eclipse running you can help me?

- open JBuilder 9
- wait forever for it to load  
- File->New Project
- Name the Project 'anything u like'
- NEXT >
- JDK: i set this to 1.4.2
 - download and install JDK SDK 1.4.2. Then in jbuilder next to the JDK Field Path click the little '...' and add the JDK...
- Required Libraries TAB:
- ADD
- NEW
- Name: JOGL
- ADD
- Locate the JOGL.jar
- OK
- OK
- ADD
- NEW
- Name: JOGL-Xtras
- ADD
- Locate the JOGL-DEMOS-UTIL.jar
- OK
- OK
- In your Required Libraries TAB you should now have:
 JOGL
 JOGL-xtras
- JBuilder will save them paths within itself so u dont need to go adding them to JBuilder again. just to your projects. this is very hand if u ask me.
- NEXT >
- FINISH
- [Ctrl] N
----
and your off.. all jogl stuff is now at your command.
to test it all just simply: 'import' the jogl stuff should be in the auto compleat  
WHEN I TRY TO RUN THE PROJECT
THE PROJECT PROPERTIES DIALOG BOX POPS UP WITH THE RUN TAB SELECTED THEN WHAT?

yep
dlls in windows/system32
jar in jdk/jre/lib/ext

text pad up and running but............

i tried running the triangle demo nothing happened can you plz give me a step by step tut on how you run your jogls. when you run the project do you run it as an applet application test opentool or how exactly.

CAN ANY ONE TELL ME WHAT IDE IS BEST SUITED FOR JOGL? Im trying to use jbuilder 9 and its killing my brain cells!

what command do you use to compile and run jogl from the command line or what is the best ide to use? ive been trying to use jbuilder 9 personal i keep getting exception in main error? hlp plz

i followed all the insructions here, when i compile the triangles tutorial i dont get any errors but when i run it nothing happens. im using jbuilder n a win xp hme ed ihave the jars and dll and the new jdk any help  
i get this exception in main error!

i have these in place already. im having trouble with the run configuration(the run project button) im not sure how to configure it. applet, application ?  :-/

thanks, i dont have any errors any more when i compile but when i run it nothing happens. no error message, nothing. perhaps im just not familiar with jbuilder, any one know how to run any of the demos? or the triangles tutorial?
