Question

使用以前在ios应用程序中使用的mtl + obj文件将3d pcb芯片加载到场景中。

使用three.js (r80)加载时，对象加载并且几何图形看起来正确，但没有纹理，颜色或图像加载到对象上。我做错了吗？

MTL file

OBJ File

mtl文件中引用的所有图像都与mtl + obj文件位于同一目录中，我看到它们被请求并正确地提供给浏览器。

在XCode中，对象看起来是正确的：

在Blender中加载，它具有正确的颜色，但不会将图像投影到对象上：

通过three.js加载它只是一个黑色物体：

JS代码我使用：

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, OnMarkerClickListener {

    private Marker myMarker;
FirebaseDatabase firebaseDatabase = FirebaseDatabase.getInstance();
DatabaseReference mProfileRef = firebaseDatabase.getReference();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

}

@Override
protected void onStart(){
    super.onStart();

    mProfileRef.child("Profile").addChildEventListener(new ChildEventListener() {
        @Override
        public void onChildAdded(DataSnapshot dataSnapshot, String s) {

        }

        @Override
        public void onChildChanged(DataSnapshot dataSnapshot, String s) {

            for (DataSnapshot child : dataSnapshot.child("0").getChildren()){
                String dob = child.child("dob").getValue().toString();
                String dod = child.child("dod").getValue().toString();

                String latitude = child.child("latitude").getValue().toString();
                String longitude = child.child("longitude").getValue().toString();

                String firstname = child.child("firstname").getValue().toString();
                String lastname = child.child("lastname").getValue().toString();

                LatLng location = new LatLng(latitude,longitude);

                googleMap.addMarker(new MarkerOptions().position(location).title(firstname,lastname).snippet(dob,dod));
            }

        }

        @Override
        public void onChildRemoved(DataSnapshot dataSnapshot) {

        }

        @Override
        public void onChildMoved(DataSnapshot dataSnapshot, String s) {

        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

}



@Override
public void onMapReady(GoogleMap googleMap) {

    googleMap.setOnMarkerClickListener(this);

    LatLng  wollongong = new LatLng(-34.404336, 150.881632);
    myMarker = googleMap.addMarker(new MarkerOptions()
            .position(wollongong)
            .title("Ben Roberts")
            .icon(BitmapDescriptorFactory.fromResource(R.drawable.marker))
            .snippet("05/06/1949 - 08/08/2016")
            .anchor(0.0f,1.0f )

    );

    LatLng  test2 = new LatLng(-34.404464, 150.881892);
    googleMap.addMarker(new MarkerOptions()
            .position(test2)
            .title("Graveyard")
            .icon(BitmapDescriptorFactory.fromResource(R.drawable.marker))
            .snippet("This is a test graveyard too")
            .anchor(0.0f,1.0f )
    );

    googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(wollongong, 18));
    googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);

    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    googleMap.setMyLocationEnabled(true);
}

@Override
public boolean onMarkerClick(Marker marker) {

    if (marker.equals(myMarker))
    {
        Intent intent = new Intent(MapsActivity.this,Info_window.class);
        startActivity(intent);
    }
    else
    {
        Intent intent = new Intent(MapsActivity.this,Info_window.class);
        startActivity(intent);
    }
    return false;
}

您是否尝试过在场景中添加一些灯光？

THREE.js没有将材料加载到对象上
