Hello again,

The video you're referring to is demonstrating the Google Tango functionality.

For your second scenario, you could either do this by augmenting a different colored plane around your target or you could try modifying the background texture. Our Background Texture Access sample is available on the Unity asset store and demonstrates how to do this.

Thanks,

Hi,

Thank you so much for the quick response .ok then having a target on the wall is a solution but in this video

(16.33) that dron scan the vertical plane and place something on that wall how do I achieve  that?

second thing I want to know is, suppose there is a picture on the wall so I want to see how it look like having colours with the wall with the picture.

Hello NilupulSimlabit,

You'll need to put a target of some variety on your wall in order to detect a vertical plane. Please refer to our Image Target documentation for further information: https://library.vuforia.com/features/images/image-targets.html
