please see attached image of one 3 point perspective.
I have the below basic questions:
where is the cone of vision?
- In one point and two point perspective, since the picture plane is perpendicular to the ground plane as we look straight ahead, we can easily identify the cone of vision by making a 60 degree cone start from the eye. please see from the attached image whether I have done the cone of vision right?
where is the picture plane?
- Is it could be anywhere? As in perspective diagram we rotate the eye to the picture plane right?
How do I know the hight of our eye?
- In one, two point perspective, we define the height of the eye by the distance between the bottom of picture plane and the horizon line. I just curious how to find the hight of the eye in 3 point perspective.
thanks so much for your help guys.
