how to add physijs to js model ? about physijs

[chandlerprall]

@tmclemons I would recommend creating your own ray-based collision detection for that purpose - a full physics implementation seems like over kill to me.

That said, you could create a box or cylinder mesh and attach the camera to the mesh. To move around you would call setLinearVelocity on that mesh with the direction you want to move.

If you have already set up the scene , you need only to change

var part1 = new THREE.Mesh( geometry, new THREE.MeshFaceMaterial() );

to

var part1 = new Physijs.BoxMesh( geometry, new THREE.MeshFaceMaterial() );

And use the appropriate Physijs Mesh in place of BoxMesh

i don't have problem by normal box
i have problem by loader model
i change code
car_loader.load( "obj/camaro/CamaroNoUv_bin.js", function(geometry) {
var part1 = new Physijs.BoxMesh( geometry, new THREE.MeshFaceMaterial() );
car_mesh = new THREE.Object3D();
car_mesh.add( part1 );
//var mesh = new THREE.Mesh(geometry, material);
car_mesh.position.set(0,2,0);
car_mesh.rotation.set(0,0,0);
car_mesh.scale.set(1,1,1);
car_mesh.add(camera);
scene.add( car_mesh );
});
but not work

and change
car_mesh = new THREE.Object3D();
to
car_mesh = new Physijs.ConvexMesh();
have error

You shouldn't add Physijs meshes to non-physics bodies (such as the car_mesh Object3D). What I would recommend is to create an invisible physics box for the car_mesh and add the geometry to that object. See #26 for more discussion on doing this (although it talks about using tQuery the principles and ideas are the same).

How would someone apply Physijs to a FPS camera? I ask because I want to set-up a camera to move via FPS through a maze, issue is I have walls that I don't want camera to go through, and I have a ramp that I want the camera to climb as it moves.

Thanks!

You would have to excuse me because my background is mostly in 3D modeling and I am new to three.js oriented coding. Would you know an example already present where I can insert the camera into the geometry and control the camera using FirstPersonControls so that it does not intersect the geometry of a wall. Thanks!

[chandlerprall]

To add a camera to a geometry: mesh.add( camera );

Unfortunately the first person controls don't have any kind of collision detection. The topic has come up quite a bit on the three.js IRC channel - I'd recommend going there and asking for advice on implementing this functionality.

@chandlerprall how can I use Physijs for ionic framework?

-Thanks in advance!
