Any 3d model loader for jogl?

Hi everybody

I am looking for a framework for making an augmented reality application in android. I have seen that this framework can be used in android and I think it could be useful for me. However I also need to load 3d models (static and dynamics, I suppuse that 3ds, obj and md2 formats) and I have not found any 3d model loader in jogl.

I have seen some questions asking for objects loaders, and anyone uses a different one (normally one implemented by their own). Those that have had experience on it, do you recommed any object loader for using with jogl? I think that it is better not to try to reinvent the wheel, if it can be avoided

Thank you and best regards
Paula.

Hi

JOGL and JOGL-utils contain several loaders for Wavefront OBJ and 3DS formats. Ardor3D contains the most robust OBJ and MD2 loaders that I know but using it under Android isn't trivial whereas it's very well under desktop environments. Ardor3D supports Collada and it has an OBJ exporter too. Good luck.

Hi !!

Thank you very much for your soon answer. I'll take a look at utils and Ardor3D and to any other suggestions  

P.D: I was really getting mad looking for 3d model formats and loaders

I advise you to look at here:

I am gonna use this thread in order to avoid to open a new one on the same argument

I just wanted to ask if the Ardor3D obj loader is still the best nowadays or some better ones came out

JogAmp's Ardor3D Continuation is the best way of loading and viewing WaveFront OBJ models, it's quite reliable even though a very few features are missing and the OBJ exporter works very well too :) I'll write a tutorial about it soon.

Edit.: It will probably support PLY, STL and BVH too in the future.

Do you have a link to pass?

Edit: is this one? http://jogamp.org/jogl-demos/src/demos/util/ObjReader.java

Ps: I have already my own stl loader (both binary/ascii), let me know if it can help

Ps2: what about Ardor3D 2? Can you describe me the current situation about Ardord 3D right now? I saw the author left and I read over internet some discussion about Ardod3d vs jm3..

No it isn't this one. JogAmp's Ardor3D Continuation is still on Github and very actively maintained:
https://github.com/gouessej/Ardor3D/blob/master/ardor3d-extras/src/main/java/com/ardor3d/extension/model/obj/ObjImporter.java

I already have a STL loader that someone else implemented but yours could be helpful if something goes wrong during the tests, in order to make some comparisons and fix it.

JogAmp's Ardor3D Continuation is alive and in a very good health, Xerxes helps me to test it with Linux ARM (laptop + Raspberry Pi). There are some explanations in the wiki:
http://jogamp.org/wiki/index.php/Ardor3D_Overview

Where did you read some discussions about Ardor3D vs JMonkeyEngine 3? JogAmp's Ardor3D Continuation is currently developed and JMonkeyEngine 3 is an interesting game development suite too anyway.

Edit.: Maybe you would have preferred to use a rudimentary loader depending only on JOGL but personally, I don't want to maintain one OBJ loader in JOGL-Utils, another one in jogl-demos and another one in JogAmp's Ardor3D Continuation. Moreover, a loader is forced to rely on some concepts and entities that have nothing to do in a Java binding for the OpenGL/OpenGL-ES API.

Here my ascii  loader and here the binary
