I'm developing an own Tobiit Eye Tracker solution, which use the gaze point for control the direction. It is already working, in window mode too. Now, the camera ride is not so comfortable and needs improvements. I will do.
To implement a good functionality I need following informations from the API:
1. Current camera direction
2. Current camera position
3. Current camera view angle
I want to map the gaze point to a direction to know where (the angle) the user is looking.
For this I need the current camera direction and view angle.
View angle is the angle (from left to right display border), which the camera current shows.
The view angle depends of the zoom. With more zoom in the angle become smaller.
I also want to set the camera direction to an absolute value. It's seems that the API currently not support it.
With the information of current camera direction and the function to set direction relative, I can set the direction absolute.
4. If current camera mode is a head camera (camera rotate around itself)
Eye Tracker function make only sense with a camera which rotate around it self.
I want to enable the Eye Tracker function only in this mode.
How can I get these informations from the API?
Thank you for your support
