[Question] How to draw the points in camera?

[letien91]

Hi. My project is targeted for iOS 8 and above. So I can't use Vision framework.
Currently, I'm using the Dlib to get the points. And I think I can get that points.
I saw your code in the demo_ios_11. And I found that you do something with the vector.

CGE::Vec2f v;
                    v = landmarks.normalizedPoints[i];
                    v = v * CGE::Vec2f(boundingBox.size.width, boundingBox.size.height) + CGE::Vec2f(boundingBox.origin.x, boundingBox.origin.y);

But I'm not good at C/C++, so It is quite confuse for me. Can you help?
Here is the data I got from the Dlib

width: 480 - height: 640
bounding box: {{494.79999, 120.68001}, {134.39999, 136.64}}
