    Point of View and Perspective

    Hi, I just finished somewhat advanced tutorial on understanding perspective
    http://c0ffeeartc.blogspot.com/2010/...rspective.html
    it might look hard at start but if you already familiar with 4-point perspective and that's where you are for now, take your time and think of how it works. It may bring your understanding of space forward.

    ----------------------------------------------------------
    Made major update! Current version is final
    ----------------------------------------------------------

    There are many types of perspective for placing stuff into 2d paper space, like 1-point 2-point or 3-point perspectives. Each is good for it's own cases.

    1-point perspective



    2-point perspective



    3-point perspective


    VP- vanishing point
    H- horizon

    Four point perspective is what usually used to make your objects pop out of the screen-paper-etc. It's really great and works fine to make things look believable.



    But there is still a way to add even more depth to your picture.
    Here is 4-point perspective if we look at it from outside


    VSP - viewer sight point
    VLP - viewer location point

    In 4-point perspective z and z' are in place but x' and y' aren't accounted.
    That's what 6-point perspective is about.





    As well as 4-point perspective takes care of the upper and lower vanishing points, Same way 6-point perspective takes into account not only vanishing points in front of you but the ones behind too.
    While Xx'Yy'Zz' graph sets space, the viewers sight point sets sphere position.

    One of important things to look here - what is closer to viewer's eyes.

    If it's still confusing - imagine 4-point perspective while looking in front of you, then look at the floor, now the upper vanishing point for you would be VPx, and the lower vanishing point would be VPx' which is behind you.


    --------------------
    How our vision works
    --------------------


    VC - vision cone
    CS - camera shot

    Our vision works somewhat like 1-point perspective, but since objects usually are not parallel to our sight direction, we use other types of perspective.
    Horizon is a circle, and we see it as line because our eyes are the center of it.
    6-point perspective is natural (6 points are vanishing points for 3 sets of parallel lines, each set perpendicular to other two) , others are it's simplified versions for use in certain cases.


    You can use this knowledge in animation, for backgrounds with pans and creating unique turnarounds, for dynamic and dramatic effects in pictures with objects close to camera, or just for your own satisfaction in understanding world better.
