Hi everybody.

1st: Sorry my english... is very poor and Tarzan style.

My question: How I can calculate the size of the virtual object should be to match the scale of the reality shows on camera?

I've tried changing the size of the tracker, resizing the printed tracker and finally changing the size of the virtual object to the eye, but do not think it in any of these ways, because there is always bad. 
There any exact method for this?
 
Thanks.

Hi Alessandro.

Thanks for your answer.. I'll trie this way...
Another question: Vuforia take control about the distance betwen camera and target for recongize it?... Because sometimes I need put the cam very close to the printed terget until take the information of this.. And sometimes at 1 mts. or a bit more, lose the track...
For example: I want put a virtual conditioner air  in the corner of ceiling and wall... the distance from the device to his virtual final position should be more than 1 m... and the cam don't reconize the track...

Some technical data (or possible solution) for this?...
Thank you again.

Hi,

you need to do the following:

- choose a unit of measure (e.g. millimeters)

- define what will be your printed target size (for example, if you plan to print an image target on an A4 paper sheet, the size should be the one of that sheet, e.g. around 210 x 297 mm)

- when creating your target with the online Target Manager, enter the width value according to the previous point

- in Unity, when using your target, use the same unit and adjust the content (other game objects) to the size of the image target in the scene, by looking at it in the Editor.
