Load .jme models

alf3299 · September 26, 2005, 9:48pm

i am new to all this jme stuff and i am trying my way arround

I would like to know if someone has a sample code on how to load .jme file into java and opengl

thanks

There are 4 or 5 of them in the jmetest area of the code. Just start digging around the test area, that will solve the majority of your questions.

cheers will have a look

i have converted a .3ds file into .jme and i already had a look in the code and tryied to load the model but got stuck because i dont know my way arround scene graph i know the commands i need to use but does not seem to work here is what i have tryied

import java.io.ByteArrayInputStream;

import java.io.ByteArrayOutputStream;

import java.io.IOException;

import java.io.OutputStreamWriter;

import java.net.URL;

import java.util.logging.Level;

URL model=HelloModelLoading.getResource("model/f15.jme");

*/

// This byte array will hold my .jme file

ByteArrayOutputStream holdsf15jme=new ByteArrayOutputStream();

// This will read the .jme format and convert it into a scene graph

JmeBinaryReader jbr=new JmeBinaryReader();

// Use this to visualize the .obj file in XML

BinaryToXML btx=new BinaryToXML();

// Send the .jme binary to System.out as XML

btx.sendBinarytoXML(new ByteArrayInputStream(holdsf15jme.toByteArray()),new OutputStreamWriter(System.out));

// Tell the binary reader to use bounding boxes instead of bounding spheres

jbr.setProperty("bound","box");

// Load the binary .jme format into a scene graph

Node f15=jbr.loadBinaryFormat(model/f15.jme) throws java.io.IOException;

rootNode.attachChild(holdsf15jme);

}

}

if u can direct me in the good way will be very nice

I am in the beginning but want to learn

Yikes, what are you adding to the scenegraph there??

alf3299 · September 26, 2005, 10:51pm

thanks

should it be

rootNode.attachChild(f15);

alf3299 · September 27, 2005, 11:12pm

can someone help?

renanse · September 28, 2005, 1:09am

uh, did you try anything new or are you just looking for the code to be spoon fed? :’(

thanks for your attention

just a comment why u say spoon feed ?

i think these forums exist to help people no ?!

so here in your forum u guys are spoom feeding everybody or trying to help people to understand and to use these libraries

is not spoon feed i twill help me devoloping what i am doing at the moment and yes i already tryied things but i dont know this librarie and in the getting started tutorial i could not understand everything.And i know that for someone that know the librarie might be be very simple to load a .jme file dont understand why this problem

anyway help is apreciated

thanks

irrisor · September 28, 2005, 7:13am

:-o This code could not even compile (uncaught exception, not implemented method, missing .class, rubbish calls). Neither does it make sense to call anything after the start() call.

Sure these forums are for help - but you ask about model loading and it seems you don't even know how to write a general jme-application.

Please try out the nice new tutorial. Then get back and have a look at the model loading example again.

alf3299 · September 28, 2005, 12:52pm

its true not many experience with jme i will try the nice new tutorial then

but is there any sample code to load .jme i am sure is prety easy

cheers i might have a different way to learn

irrisor · September 28, 2005, 1:04pm

Sure, when you have a look at HelloModelLoading again: everything related to 'converter' and 'btx' is not needed to load a jme-file. Then instead of doing

Node maggie=jbr.loadBinaryFormat(new ByteArrayInputStream(BO.toByteArray()));

do

Node maggie=jbr.loadBinaryFormat(model.openStream());

That's it.

alf3299 · September 28, 2005, 1:10pm

cheers i will have a go

and after i tell u the results

alf3299 · September 28, 2005, 1:20pm

btx is binnary to xml right i thought it was needed u see like i am starting to understand tks

i have not tested yet i am having lunch after i tell how it went

alf3299 · September 28, 2005, 1:28pm

shouldn t this work i removed all converters and btx

what about learning Java and using an IDE first?

alf3299 · September 28, 2005, 1:45pm

can u just say what i wrong with the code pleass or put same sample code i easier for me to learn jme

thanks

darkfrog · September 28, 2005, 1:48pm

I would suggest downloading the source for jME and looking at the test code there. I'm sure you can understand we don't really want to have to explain jME in a thread for every new user. That's why we have the wiki and the Tests that are in the source code for people to look at. If you have questions on either of those feel free ask. We're here to help, but we try to keep the hand-holding to a minimum.
