TargetCamera3D problem in looking at an object from the top

[Miroku]

Hi everyone,
I have this little piece of code:

board = new Board(1500,20,1500); //extends Cube
camera = new TargetCamera3D({target: board});
camera.focus = 10;
camera.zoom = 100;
camera.z = -1500;
camera.y = 500;

away.view.scene.addChild(board); //away it's my UIComponent
away.view.camera = camera;

and I get this render: http://dl.dropbox.com/u/4064417/away3dboard.png

When the code is like this:

board = new Board(1500,20,1500); //extends Cube
camera = new TargetCamera3D({target: board});
camera.focus = 10;
camera.zoom = 100;
camera.z = 0;
camera.y = 500;

away.view.scene.addChild(board); //away it's my UIComponent
away.view.camera = camera;

I get this render: http://dl.dropbox.com/u/4064417/away3dtop.png

Instead, when it's like this:

board = new Board(1500,20,1500); //extends Cube
camera = new TargetCamera3D({target: board});
camera.focus = 10;
camera.zoom = 100;
camera.z = 0;
camera.y = 10;

away.view.scene.addChild(board); //away it's my UIComponent
away.view.camera = camera;

I get this: http://dl.dropbox.com/u/4064417/away3dtop2.jpg

Why this behaviour? It seems that the camera does not rotate itself to
look at the target object....
How can I solve it?

No one can help me?

Do you want something like this? http://www.veritasdigitalstudios.com/Nintendo/dice/06/ im using this camera code

camera = new HoverCamera3D();

camera.distance = 200

camera.panAngle = 0; 

camera.tiltAngle = 89; <---- try with this, i used 89 cuz on 90 does not show anything

Sorry for my english :P

Article with TargetCamera3D targeting mouse selected object:

Article with TargetCamera3D following mouse selected object:

http://www.allforthecode.co.uk/aftc/forum/user/modules/forum/article.php?index=4&subindex=2&aid=104

So between those two articles you have TargetCamera3D targeting and positioning.

From the top of my head I would write something like this and then adjust...

// Away3D setup etc

camera = TargetCamera3D();

sphere = new Sphere();

//sphere position bottom at y 0

sphere.x = 0;

sphere.y = 0;

sphere.z = 0;

scene.addChild(sphere);

// Camera position top at y 1000

camera.x = 0;

camera.y = 1000;

camera.z = 0;

// Targeting

camera.target = sphere;

//or

camera.lookat = new Vector3D(0,0,0);

// Rotations

camera.rotationX = 0;

camera.rotationY = 0;

camera.rotationZ = 0;

Ehi thank you,
In the end I solved it myself using this piece of code:

camera = new TargetCamera3D({target: board});

camera.lens = new OrthogonalLens();

camera.focus = 10;
camera.zoom = 100;

camera.y = 1000;
camera.pitch(90);

The orthogonal lense is there 'cause I needed to move objects and see
their position without perspective.
I needed this camera just to do this so if it's not good coding
matters little =)

Thank you again ;)
