Hi all,
I've published a new model viewer into Google play. It can open model from online storage.
In case you want to try  it:

You can see details of feature there.
Thank you

P/S Dear Admin, please help me to delete it from Java group. Thank you

Maybe, rainfalls said right, although I use other thread to add new object to World, World is still blocked during compiling time -> multithread not effective.
Thank you all.

I got 1st frame rendered, then no update until loading finished.
What do you mean "shader files"?
I saw only  connection between 2 thread(loading and render) is world:
+ In Loading Thread: Add new object to world if any ready loaded
+ In Render Thread: Render world

Do you think world is blocked during Loading thread running?

Dear,
I 've used an other thread to load model 3d into JPCT-AE world. However, Rendering is still blocked at render time 1st(we can see 1st frame) until finishing loading.
The way I do:
1. Start loading data thread at onSurfaceCreate
//Create world
new Thread(new Runable(){
//Load 3ds model which has not been used at starting time yet.
}).start();
2. DrawFrame: Normal update world(example move Camera). It should be not blocked by data loading, it means other data should be updated normally.

I don't understand why, please help

Thank you.

Thanks ad.
Because I want to show 3DS file instantly after download from free source, it  must be 3DS format.
In that case, if I want to show 3DS file loading status, which API can I use?
In 3DS loading example, you use
  Object3D[] model = Loader.load3DS(is,scale);
           Object3D o3d = new Object3D(0);
           Object3D temp = null;
           for (int i = 0; i < model.length; i++) {
               temp = model;
               temp.setCenter(SimpleVector.ORIGIN);
               temp.rotateX((float)( -.5*Math.PI));
               temp.rotateMesh();
               temp.setRotationMatrix(new Matrix());
               o3d = Object3D.mergeObjects(o3d, temp); //almost time
               o3d.build();// almost time - redundant build
           }
It's possible to show status after each mergerObjects.

However, I improve loading time  and memory by :
Object3D[] model = Loader.load3DS(is,scale);
           Object3D temp = null;
           for (int i = 0; i < model.length; i++) {
               temp = model;
               temp.setCenter(SimpleVector.ORIGIN);
               temp.rotateX((float)( -.5*Math.PI));
               temp.rotateMesh();
               temp.setRotationMatrix(new Matrix());
           }
             o3d = Object3D.mergeAll(model);// almost time
          o3d.build();// almost time

All time is for mergeAll and build, is it impossible to get status during mergeAll and build?

Dear,
I'm making a 3DS viewer using jPCT-AE.
I see 2 problems:
+ Memory consumption is very big for loading a 3DS model : I enabled large heap to use  availble memory for loading., it takes ~100MB memory to load ~5MB 3DS file.
+ Loading time is too long: If 3DS file is 5MB, it take some minutes to load.

I don't think 5MB is a big data for a tablet such as ASUS TF300T.
As a reference, my friend uses Ogre-Android to load ~2M Mesh file, it takes only ~1s.

So, can you share me what limitation of current jPCT-AE for big data? Maybe the issue is inside loader code or creating Object3D ( mergeObject, mergeAll,...)

Hardware: I'm using Transformer TF300T

Thank you
