Positioning content after target disappears

June 30, 2015 - 11:30pm #1

Hi,

I need to position some content in the middle of the screen (meaning, cnstant position) after the target disappears.

The problem is that the position changes according to the last place the target was seen at. This makes sense, since the pose matrix is relative to the target. But how can I reset the coordinates when a target is not visible, so my drawing will always be at a constant position?

 

Thanks,

Positioning content after target disappears

Hi!

I have similar issue with augmentation.I can render image on trackable.

when i take the screen off the trackable,the content is being rendered in the centre which is quite impressive.Now the issue is,the content rendered offtarget is very small.I need to resize it.Where can I change the code to get the augmentation with redefined size when we take the screen off the trackable.

Any sujjestions would be helpful!

Thank you!

Hi,

Well, I was able to solve this out myself, so I wanted to share it in case it can help someone else.

The problem was the projection matrix  - I had to set one that suits my requirements at the app initialization, and use only that one when I want to draw something at a constant location, regardless of the target.
