I want image to move along with me

[Nithin]

Hey ,

I want a option panel which i will create to move along with me at certain distance along with me. 
is it possible to do so using script?

Hello Nithin,

To be able to do that in OpenGL, it is needed to have access to World Matrix and Camera Matrix.

More details about various matrix and math behind that in 3D Open GL API.

By the way, it is the same in DirectX also

As far, I know, in Vuforia Studio, we don't have access directly to these matrix.

I am checking that internally at PTC to be sure.

The idea, is to convert 2D UI world coordinate to 3D world position.

After that, we can apply that to the 3D plane object (a billboard with only one face visible)

In Vuforia Studio, in 3D Label, 3D Image, and 3D Gauge, we have a Property named Billboard to do that.

• Does these Widgets can fit the panel needed in your Project ?

Best regards,

Samuel

Hi @Nithin,

I think this is possible as already mentioned by @sdidier  using only 3d elements in Studio ,where you can use the click event on them involving your menu /menu option functionality.

This will be possible after some calculation via the 

tml3dRenderer.setupTrackingEventsCommand()
