Hello,
I have been integrating a facial detection SDK (http://www.visagetechnologies.com/) with Unity.
At every Update() cycle I am able to obtain a set of normalized coordinates [x,y] of the face feature points. (0,0) = bottom left of the screen, (1,1) = top right.
I would like to display sphere at each of these points on the screen for debugging. How can I convert this normalized coordinates to display the sphere objects correctly on the screen?
Easiest thing to do is use a Canvas, and create UI elements for each point. Set their .anchorMin and .anchorMax coordinates to your [x,y], and they should all be in the right spot.
Second-easiest, if you’re intent on using spheres, would be to set up an orthographic camera with a size of 1 at coordinates (0.5, 0.5, -100) facing forward. Then you can set your spheres’ positions to [x,y,0] and they’ll show up in the right spot. (Be advised that the standard sphere defaults to a size of 1, which would fill the screen; you’ll want to scale it down to like (0.05,0.05,0.05) or something. )
