Imported .obj mesh when changing positions becomes unmanageable

[Alex10]

After I import the mesh, if I don't change his position and if I don't change the camera's position, all is well.
But I want after loading the mesh entirely intermeddle in screen, without zooming with the mouse wheel.
If I change the mesh position it becomes impossible to twist the mouse.
 

mesh.onSuccess = function (task) {
   m = task.loadedMeshes;
   for(var i = 1; i < m.length; i++) {
      m.position = new BABYLON.Vector3(25, -250, -40);
   }

If I change the camera position also becomes impossible to twist the mouse.

var cam = new BABYLON.ArcRotateCamera("ArcRotateCamera", 0, 1.8, 5, new BABYLON.Vector3(170, -50, 10), scene);

Working option but the mesh won't fit in the screen.

After the change of position of the mesh loaded it does not work normally turn the mouse.

If you change the camera's position is also that the mesh can't be controlled.

Hey I guess there is a misunderstanding here: the camera does NOT control the mesh. It rotates around a center. 

 

In your case if you move the mesh then the camera does not rotate around it because the mesh is not on the center of the camera

 

i suggest just taking your first example and increment the radius of your arcrotatecamera: 

var cam = new BABYLON.ArcRotateCamera("ArcRotateCamera", 0, 1.8, 30, new BABYLON.Vector3(170, -50, 10), scene);

 

[Alex10]

Work with this option:
 

camera.setPosition( new BABYLON.Vector3( 216, 93, -17 ));

http://178.62.253.28/  test page

But for me this is not an option. Because I need to automatically calculate these values BABYLON.Vector3(216, 93, -17). And I don't know how to do it.

I need to boot the entire model got into the screen.

I can easily calculate how much to scale the model, but then I can't do it normally to turn the model with the mouse.

http://178.62.253.28/test test page

Which method is to automatically set the position of the camera so that when load the model is fully intermeddle in the frame?
Or maybe there is a way to force the model to turn normal mouse after scaling?

To go further, can you please create a playground. This way I will be able to fix the code for you

[Alex10]

Ok, But I did not succeed in the playground I need to load a model in format .obj. Probably this limitation of the playground.
Model and texture normally given for this:
http://178.62.253.28/f/mesh.obj

http://178.62.253.28/f/dif.png

This is the code with the set manual in the camera position:

This is the code with scaling of the model:

[GameMonetize]

Are you looking to the real center of your object? then use: mesh.getBoundinfo().boundingSphere.centerWorld as your vector3

[Alex10]

That it will give me?
In this case (mesh.getBoundingInfo().boundingSphere.centerWorld), the coordinates  {x: 0, y: 0, z: -0.000014999999997655777}.

What to do with these coordinates?
 

[GameMonetize]

Ok perhaps I misunderstood.

What does ( 216, 93, -17 ) represent?

[Alex10]

camera.setPosition( new BABYLON.Vector3( 216, 93, -17 ));

@Deltakosh This manually set position of the camera in which this model got into the screen. And I need to automatically calculate this position.

I need to page load any model got into the screen. Like sketchfab.com. For this I need to automatically calculate the camera's position. How to do I don't know.

[aWeirdo]

If you are using arcRotateCamera, and i understood you correctly, simply setting the camera target to the mesh position would keep the the center of your mesh as your camera's target even if the mesh is moved.

Example:(after mesh have loaded)

yourCam.target = yourMesh.position;  

 

Edit:

You also wrote that the mesh doesn't 'fit' in the screen, increase camera view distance.

//the field set to 50 is the "view distance" field.

BABYLON.ArcRotateCamera("ArcRotateCamera", 0, 1.8, 50, new BABYLON.Vector3(0, 0, 0), scene);

[Alex10]

@aWeirdo  Yes I am using arcRotateCamera. I wrote  cam.target = mesh.position;  but the model does not fit into the screen.

For example:
http://178.62.253.28/test2

[aWeirdo]

Your mesh is very large, there are two options, scaling it down, or zooming the camera out(see the edit on my previous post)

[Alex10]

@aWeirdo Ok, When I scaled the model, the model becomes unmanageable fine.
for example: 
http://178.62.253.28/test

How to calculate a zoom on the camera? I need zoom to set automatically. Or to set automatically camera.setPosition()

[GameMonetize]

You can evaluate the zoom (radius) by getting mesh.getBoundingInfo().boundingSphere.radiusWorld * 1.1 (or a bigger constant)

[Alex10]

If I multiply these coordinates:
{ 0*1.1, 0*1.1, -0.000014999999997655777*1.1 }  
Then I'll have the following coordinates for "setPosition"
cam.setPosition( 0, 0, -0.000016499999997421355 )
and get this result:
http://178.62.253.28/test    -  model not got completely into the viewport

and I need to get around these coordinates
cam.setPosition( new BABYLON.Vector3(216, 93, -17) );
http://178.62.253.28/     -    model got completely into the viewport

How do I get the coordinates of the camera in which the model will got completely into the viewport?

[GameMonetize]

What I suggest is to set arcRotateCamera.radius to  mesh.getBoundingInfo().boundingSphere.radiusWorld * 1.1

 

Look: http://www.babylonjs-playground.com/#I7U4M#4

[Alex10]

Exactly, I think this is what I need. How I can the model change color or texture when I click on button?
Event occurs but the error occurs.

$('#button').on('click', function(){
   console.warn('Yes');
   m[i].material = new BABYLON.StandardMaterial("texture1", scene);
   m[i].material.diffuseColor = new BABYLON.Color3(1, 0, 0);
});

For example:

Like this: http://www.babylonjs-playground.com/#I7U4M#6

[Alex10]

Yes this is what I needed, thank you very much.
