Starfire 3DS Loader
Hi, can someone tell me the clear steps for install "StarfireExt.jar"?
I have copy it to both C:\j2sdk1.4.1\jre\lib\ext and C:\Program Files\Java\j2re1.4.1\lib\ext. Is it something missing?
The other problem is when I run the program by using Loader3DS, the error message is "Not Supported 3DS", when I change to Inspector3DS, the error message is "java.lang.NoClassDefFoundError".
Please help me! Thanks!
There is a txt file that comes with it that has instructions on where to place the jar.
import com.mnstarfire.loaders3d.Inspector3DS;
public TransformGroup loadTestObject() {
if(DEBUG) System.out.print("Import 3ds object...");
Inspector3DS loader = new Inspector3DS("lyrax.3ds");
loader.parseIt(); // process the file
loader.setDetail(9);
loader.setLogging(true);
loader.setTextureLightingOn();
//loader.setCreaseAngle(1.0);
TransformGroup theModel = loader.getModel();
theModel.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
if(DEBUG) System.out.println("done.");
return theModel;
}The import obviously at the top and the DEBUG is my own code.

View Problems with Starfire 3ds Loader
Hi all !!
I am new on developing 3D Applications with Java (only tryed several DirectX Programing with C).
I've studied the SUN Tutorial of 3D Programming (first 3 Chapters) and now started to load a complex 3ds Object. I've tested several loaders and now the Starfire loader looks like working, because there is no exception during the loading process.
But the model isn't shown. I've tryed several 3ds models with differend sizes, but nothing happend i only got the black Applet view. I've tryed both loading Objects types, but i still got the same problem.
I thougt there is a problem with the view distance. Is there a easy way to change the translation like in C? Or is there an other failure I've make? Can someone help?
Thanks in advanced !!
ChristianChristian,
we have made very good experience with the starfire 3ds loader. I think there is no better one at this point of time.
The problem might be one of the one described below, distance, size and lights.
I can offer you to use AniFun3 (http://www.anifun3.de) at your first steps. It is a visual interface to the 3D api and contains the Starfire3DS loader. You can easy change the size, the point of view, lights etc.. on the fly. The graphical user interface is similar to the api. Therefore after successfully importing a file, you can continue either with AniFun3, or manually transfer the values to your source code.

Why can I load only 8 models into a program
Hi, i have a java progrem , and i work with NCSA portfolio , or Starfire 3DSLoader (i tried them both)
and the loader , lets me load every time only 8 models simultanitly, when i load more than 8 , it just doesn't show them , until i remove other loaded models (from the 8 loaded)
what can i do to fix it?
plz helpIt's like this - I wanted to let the user choose a model , from a variety of 20 models ,
so i craeted a jframe , and within i added 20 jpanels , and each jpanel , had a model loaded into him (with Canvas3D...)... Now , when i run the program , only 8 models are shown in their jpanels , and all the other jpanels are blacked out (the model is there , but just doesn't show)...
Now when I remove a working jpanel in runtime (that has a model in it ) , then one blacked jpanel, is now working, and the model inside is shown...
that's how i figured out, he let me load only 8 models each time....
How can i solve tshi problem????????
(I tried to work both with Starfire 3DS loader , and with NCSA porfolio , and in each of the the problem occured) -
Beating my brains out: How do you move a 3DS object in order to see it?
Can someone plese explain this to me in nice detailed steps. I just can't seem to get it to work.
OK,
I can load (using the StarFire 3DS loader) 3ds images just fine like this:
Scene theScene = null;
Loader3DS loader = new Loader3DS();
theScene = loader.load("D:\\My3dsFile.3ds");
Some .3ds files I can see just fine. Others look like they need to be scaled/translated. I noticed this by creating a ScaleInterpolator and applying it to the root BranchGroup on one of the .3ds images I could not see like this:
TransformGroup objTrans = new TransformGroup( );
objTrans.setCapability( TransformGroup.ALLOW_TRANSFORM_WRITE );
Transform3D zAxis = new Transform3D( );
zAxis.set(new Vector3f(0.0f, 0.0f, 10.0f));
Alpha xAlpha = new Alpha( -1, //Loop
Alpha.DECREASING_ENABLE |
Alpha.INCREASING_ENABLE,
1000, //trigger time
1000, //phase delay duration
5000, //increasing alpha duration
1000, //increaing alpha ramp duration
1000, //alpha at one duration
1000, //decreasing alpha duration
2000, //decreasing alpha ramp duration
1000 ); //alpha at zero duration
ScaleInterpolator scale = new ScaleInterpolator(xAlpha,
objTrans,
zAxis,
-6.0f,
6.0f);
scale.setSchedulingBounds( getBoundingSphere( ) );
objTrans.addChild(scale);
bgRoot.addChild( objTrans );
objTrans.addChild(theScene.getSceneGroup()); //theScene = .3ds scene
Doing this, I can catch a glimpse of the .3ds image every now and then.
How in the world can you scale a scene and move it to the 0,0,0 position?
All I want to do is load a stinking .3ds image (any .3ds image) and be able to view it! I think if I could scale it and move it to 0, 0, 0 then I should be able to see them.
Please help.
Thanks.Have you tried to scale the object uniformly at creation, before putting it in a scenegraph? this way at runtime you don't need to worry about objects being to big at runtime...
for the uniform scale:
Transform3D transform = new Transform3D();
transform.setScale(0.02); //try different values here
3ds_object_transform_group.setTransform(transform);
Another thing you could do is to use a 3D modelling program (like 3DS)
and scale the object very very small..
I had the same problem before, hope this helps -

}My guess is that you are using the ObjectFile loader, which is for a (don't remember which application) object (.obj) file, rather than using a 3ds loader, which would be for loading a .3ds file.
You might want to go to this page: http://www.j3d.org/utilities/loaders.html and download the correct loader. -

Are there any complete APIs for loading 3DS models in JOGL? I can't seem to find this anywhere? If not 3DS, is it possible to load any other type of models?
JOGL is just an OpenGL wrapper. Basically it gives access to OpenGL API methods and fields. You need some kind of a structure above JOGL in order to do more advanced stuff. There are several 3D engines using JOGL to access the OpenGL API. These engines normally come with loaders for different file formats. I don't know all Java 3D-engines, but you could try using AgentFX (http://www.agency9.se/agentfx). It doesn't have a 3DS-loader, but an OBJ loader. Almost all 3D programs can save to OBJ format. You can use Milkshape 3D (http://www.swissquake.ch/chumbalum-soft) or some other program to convert your 3DS file into OBJ.

which export type in 3Ds max 4 can be used in conjunction with java?
i know this is said in one tutorail, but currently adobe isnt compactible with my O/S so i need someone to help.
thanks in advance,
pop n freshi agree with OFH Starfire research loader is quite good. unfortunately it doesn't support some surface/texture features (reflection mapping for exemple) that can be implemented in Java3D and the source code is not given.

How to use utility jars without -cp
I am trying to use a 3d loader from starfire research to load .3ds files. I currently have the jar in /lib/ext and netbeans sees this and uses it, and everything works perfectly fine. When I use this on other machines for a test, I put the 3d loader jar in to the client /lib/ext folder, but my program cannot find it. Any suggestions on where to put this jar without me having to use -cp every time?
Thanks in advance.I'll try to explain better. The 3DS Loader I'm using is called StarfireExt.jar. I have two computers that I am using right now: a custom built desktop with Windows XP 32 bit that runs Netbeans, and a Dell laptop that I'm using to test my software. On the desktop, I have JDK1.6u18 with Java3D also installed. StarfireExt.jar is in my C:/Program Files/Java/jdk1.6.0_18/lib/ext/ folder, and Netbeans allows me to import and use StarfireExt. On the laptop, I have JRE1.6u20, Java3D, and StarfireExt in the lib/ext/ folder. When I'm on the desktop in Netbeans and press F6, it runs fine and the 3DS files load and are displayed. When I clean and build the JAR and move all of the models and JAR to my laptop, the program seems not able to find StarfireExt. The models don't load; no error windows that I've coded pop up.
P.S. I'm sorry if I'm kind of a Java newbie. I don't know all those awesome developer tricks yet. -

}A simple grey floor with 2 texts objects on it, right mouse button moves "jeden" to the left, while "jeden" intersects "dwa", "dwa" rotates around its X axis, then, when "jeden" stops moving you can click again to force the movement in right direction, so that "jeden" is going to intersect "dwa" once again. The thing is, that while "jeden" moves left everyhing is allright, "dwa" rotates as long as both objects remain in collision, however, as "jeden" moves back (that is in the right direction) "dwa" keeps rotating even though they are not colliding anymore. The best way is just to copy /paste that code and try it out to observe what kind of problem i am facing.
Another question : how can i rewrite that code, so that "dwa" object could do something on wakeupOnCollisionExit, for example move up.

}everything works fine apart from one thing, if i either move too high or to far away, the object along with ground dissapear, at first i though that must be the matter of boundingsphere which obviously might have been initialiazed as too small, so i changed the constructor to expand it to 1000 from 1 (as is it set in default constructor) however that didnt help either, whats is the problem then ?

KoniecznyI can`t see anything wrong with your code.
There may be an issue with the front or back view clip. See the javadoc for View for details. Or there may be an issue with z-buffer settings on the video card.

Hi!
I would really appriciate if someone could help me with this.
I have to travers all the nodes in one tree, from one BranchGroup, to all the leaf nodes in the tree, to get the Shape3D generated by a 3ds-loader.
I would like a method that takes the BranchGroup as argument and then for all the leaf nodes sets the capability bits for each. Does anyone have that code or have a simple example how I should do this?
Regards,
HenrikThis should be pretty straightforward. If you have the branch group, then you are all set. Simply traverse the scene graph recursively, using leaf nodes as your base case for returning. So your algorithm will look something like this:
public void findAllShape3DNodes( final Node parentNode )
int numChildren = parentNode.numChildren();
for( int i=0; i<numChildren; ++i )
Node node = parentNode.getChild( i );
if( node instanceof Shape3D )
// Do whatever you need to do to this Shape3D
else
findAllShape3DNodes( node );
}That's the general gist of the algorithm. Of course, you will have to modify it to suit your needs, but in general that is the idea you want to follow. So the parentNode parameter to the method will be the branch group that you picked. You send that branch group to the method and it iterates over its child nodes, searching for Shape3D objects. If it finds a Shape3D object, then does whatever you wanted to do to that node. If it isn't a Shape3D node, then it must be some other kind of node (might want to check that its not any other kind of leaf node, but with this algorithm it shouldn't make a difference since a leaf node has no children). If its some other kind of node, recur on that node and iterate over all of its children, and so on.
Hope that helps!
Cheers,
Greg -
I am using those MD2 & BSP loaders (found in J3D.org) in my project, but I have problems setting them up to work with my collision avoidance. With the MD2s, I can set the appropriate capabilities for a static model, but when it is animated, I get exceptions. I have tried loading all of the frames and setting capabilities for each, but this does not seem to make a difference.
The other, more serious problem is with the BSP (level) files. I cannot seem to set the capabilities on these either. I try, using the code below (where bgIn is the BranchGroup from the BSP):
Vector groups = new Vector();
int currentGroup = 0;
groups.add( bgIn );
Enumeration eGroup;
Object oGroup;
Enumeration eShape;
Object oShape;
while( currentGroup < groups.size() )
eShape = ((Group)groups.get(currentGroup)).getAllChildren();
while( eShape.hasMoreElements() )
oGroup = eShape.nextElement();
if( oGroup instanceof Group )
groups.add( oGroup );
else if( oGroup instanceof Shape3D )
((Shape3D)oGroup).setCapability( Shape3D.ALLOW_GEOMETRY_READ );
eShape = ((Shape3D)oGroup).getAllGeometries();
while( eShape.hasMoreElements() )
oShape = eShape.nextElement();
System.out.println( oShape );
((Geometry)oShape).setCapability( GeometryArray.ALLOW_COORDINATE_READ );
((Geometry)oShape).setCapability( GeometryArray.ALLOW_FORMAT_READ );
((Geometry)oShape).setCapability( GeometryArray.ALLOW_COUNT_READ );
currentGroup++;
When I do this, the level only seems to be made of one Shape3D, which includes just one TriangleFanArray, which I cannot believe is correct. When I touch a wall, I get a javax.media.j3d.CapabilityNotSetException: Shape3D: no capability to get geometry. Is there something wrong with this code, or some other way to do this?
ThanksOuch, this brings back painful memories for me. I had similar problems with importing .3ds files but it was a long time ago and I don't have the code to hand. I do recall, however, after much toiling I eventaully went through and set ALL the capabilities of the Shape3Ds possible similar to some of your code:
((Geometry)oShape).setCapability(GeometryArray.ALLOW_COORDINATE_READ );and then removed them one by one to find out which capability was needed to stop the Exception. (This was all done by modifying the 3ds Loader code BTW - I was using 3ds Loader by Richard Hawkes, also from j3d.org)
Sorry I can't be of more help, I know how irritating it is :( -
I've written a small 3DS loader, but now I've run into the problem of storing the information. When I load one model, there are the XYZ coordinates and ABC for the faces. Coordinates are extracted from the file as floats then converted to integers with a small loss of precision and the faces are integers as well.
This is really a problem of storing multiple(~20) large arrays(~200) of 6 integer arrays. I was thinking about doing a bit wise operation to convert the 6 arrays into one long. 2 bytes for each x y and z then store each face as one byte. But, this gives me multiple large arrays of longs. Also limiting the amount of polygons I have to 256.
I'm sure I'm over complicating this so I figured I would ask if there is a simpler method.Hello,

Based on your numbers, you're talking about storing 20*200*6=24000 integers, i.e. 96kB. Not a big amount in the RAM of a regular desktop computer - but maybe you're running on a more limited device? Please clarify if this is the case.
This is likely not a big number either in terms of file storage.
Is your problem the fact that you don't know how to code this "storage"? Then search about "Java serialization" (of course a lot of other approaches exist).

Java3d - starfire: Where is my 3ds object?
