Keeping a gamobject in 3d space in front of the camera as if fixed on a display?

Question

I want to calculate the position and orientation in 3d space to place a gameobject so that it appears in the same position and orientation in front of the camera as the camera moves around in 3d space.

I have only one slight problem, I have no idea how to calculate this (3d position and orientation). :-(

Does Unity provide any method to handle this? Is there a way to convert a screen coordinate from the camera display to a 3d point and direction in space?

Thanks for any help!

Camera.ViewportToWorldPoint is what you need.

Hi,

I'm not quite sure what you're asking for....

If so... try this tutorial

I find that SpeedTutor is a really good person to watch for tuorials.

Sorry if that isn't what you meant....
