Question

To make bounding box i use this code:

  'vtk_bounding_box': function(data) {  
                    if ((browser == 'explorer') ||(THIS_IS_TOUCH_DEVICE)) return;
                    var geometry = new THREE.Geometry();
                    var material = new THREE.MeshBasicMaterial({color: 0xFF0000,wireframe: true});
                    box_info = '';

                    for (var i = 0; i < 8; i++){
                        box_info += i+': x:'+ data[i].x +'y:'+ data[i].y +'z:'+ data[i].z
                        geometry.vertices.push( new THREE.Vector3( data[i].x - FocalPoint[0],  data[i].y - FocalPoint[1], data[i].z - FocalPoint[2]));                
                    }                   

                    //Making Bounding Box
                    geometry.faces.push( new THREE.Face4(0,1,2,3));                   
                    geometry.faces.push( new THREE.Face4(2,3,4,7)); 
                    geometry.faces.push( new THREE.Face4(4,5,6,7)); 
                    geometry.faces.push( new THREE.Face4(5,6,1,0));
                    geometry.faces.push( new THREE.Face4(1,2,7,6)); 
                    geometry.faces.push( new THREE.Face4(0,3,4,5));

                    mesh = new THREE.Mesh( geometry, material);                 
                    scene.add( mesh );
                },

and when i change type of rendering from webGl to canvas?And when i rotate this, part of model just disappears sometime. I want to say that it can show full model? but after some rotation in can drow only few lines

To make it work in CanvasRenderer you need to make the material double-sided. In r.50, you do that like so:

var material = new THREE.MeshBasicMaterial( { color: 0xFF0000, wireframe: true, side: THREE.DoubleSide } );
