i'll try that, thanks!

I don't want the shadow or the part where the light isn't reached to be dark.

Hi, I would like to know how can I make the light visible from every direction?
I don't want it to be dark on one side and not the other.

thanks!

Hi, thanks for replying, soo...

how do I share the model with you?
Can you check that? I got the GLB file from my windows 3d viewer library and converted it into 3ds.

I have been experimenting with JPCT and everything was fine.
I had converted a GLB file into a 3ds file so that I can use it with JPCT, the model is correctly displayed with various online 3d viewers, but when I try that in JPCT when I rotate it, some parts of the object seem to be disappearing. I tried rescaling the model while loading and trying on another device, the issue is still present.

This is how I load the Object3d:


ModelAvailable(
                        Object3D.mergeAll(
                                Loader.load3DS(tools.getStream(model), scale)
                        )
                );


This is the problem with only this model, other models are correct

I am new to 3d models and handling them, I want to know if there are any examples to detect collision between two objects? 

So far I have tried

First model:


object3D.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS | Object3D.COLLISION_CHECK_SELF);
        object3D.addCollisionListener(new CollisionListener() {
            @Override
            public void collision(CollisionEvent collisionEvent) {
                Log.d("Renderer", "collision: " + collisionEvent);
            }

            @Override
            public boolean requiresPolygonIDs() {
                return false;
            }
        });


And


((MyModel) mymodel).getObject3D().setCollisionMode(Object3D.COLLISION_CHECK_OTHERS | Object3D.COLLISION_CHECK_SELF);
        ((MyModel) mymodel).getObject3D().addCollisionListener(new CollisionListener() {
            @Override
            public void collision(CollisionEvent collisionEvent) {
                Log.d("Model3d", "collision: " + collisionEvent);
            }

            @Override
            public boolean requiresPolygonIDs() {
                return false;
            }
        });
        SimpleVector vector = new SimpleVector();
        vector.y = 10;
        ((MyModel) mymodel).getObject3D().checkForCollision(vector, 100);


So far, the event is not triggered 
Am I missing something?

How do I listen to collisions?

This works perfectly, thank you very much

thanks, I will try that out!

Hi can you please help me with this?

here by loading model I mean, the model is loaded correctly from the file (3ds object) but adding it to view using GLSurfaceView creates this behaviour

When I click button 2 to load the second model, it moves by itself and sometimes i also crashes

Here is the link to the video uploaded in Google Drive:

I will attach a screen recording of it in 10 mins.

hi, i am new here, I am using JPTC for android, its working good, but when i load the second another model and Add it to a view, it makes it behave weirdly, can you please help me
