    perspective and vanishing point

    the placements of vanishing points don't have to be at the opposite ends of a horizon line right?

    can there be more than 3 vanishing points?

    how do i draw something with vanishing points outside of the paper on which i am drawing something?

    Yes they have to, otherwise the image will look distorted. Try drawing a cube where the vanishing points are close together.

    "can there be more than 3 vanishing points?"

    Are there more than three (visible) dimensions? (NO)

    "how do i draw something with vanishing points outside of the paper on which i am drawing something?"

    Most of the time the objects you draw will be too big to fit their vanishing points on paper and still make the objects look good. After you learn the basic rules, you can practice freehand perspective, where yoy just assume the vanishing poinst are far away and just use perspective rules and your judgement to make it look right. Check this tutorial for more info: http://www.conceptart.org/forums/sho...84#post1485584

    PS: Don't be shy and use the search function (or use google to search the forum), there's lots of great info to be found.

    WRONG.


    Four-point and Five-point can be used by artists in extreme situations, somewhat similar to using a fisheye lens in photography (Four-point), or (Five-point) projecting imagery onto a spherical surface (like drawing on the inside of a bubble or globe). There's also six-point possibilities that act as a kind of wrap-around panoramic view (in front and in back of you simultaneously). 5- and 6-point perspective are difficult to plot and difficult to easily grasp for most people, but 4- point isn't bad if you keep your wits. There are drawings and paintings in existence that have examples of 4-point perspective.

    Nicely put, that made me laugh.
    Four-point and five-point perspectives are fun and difficult to draw, and usually appear as Escher-ish distortions because the brain somehow refuses to process them in reality. Walk up to a building, stand close to a wall - best if it's a brick wall with all those lines to guide the eye. Look left and right and you'll see vanishing points clearly. Up and down, likewise. Windows or jutting pipes will show a fifth vanishing point directly ahead. But good luck trying to see all of these at once - or maybe my brain is broken?

    Thank you for inspiration, you made me start playing with perspective tonight. Attached quick sketch shows four-point perspective building. Technically six-point as the missiles and gun barrels have own vanishing points but those don't really count as they are merely the horizon-points moved to accomodate tilt.

    As for your second question..vanishing points that are actually off the paper? You can use a vanishing line as shown here. Its ends will be defined by extreme ends of the object you are drawing, in the case of this sketch the peak of the building, and welcome mat. Anything in between is drawn according to a line that's proportional to that line segment....does that make sense?

    how does a measuring point work?
    how do yo go about to place it for a horizontal scale?

    My bad guys. Here's a link that explains the multiple point perspective a bit further: http://www.2d-digital-art-guide.com/...rspective.html
    (or this one: http://www.termespheres.com/perspective.html)

    I understand that these perspectives are used to exaggerate things, but is it even possbile to observe 4+ point perspectives? Looking at crises' drawing, observing such distortion is only possbie if you can look up and down at the same time (like crises states). If you want to observe the whole builiding you have to step back until the whole building is within you eyesight and at that distance the vertical lines will be parallel and not converge to the upper vanishing point and the lower one.

    Needing at least some reference understanding is more common than you think. Four- and Five-Point becomes a factor when you think about reflections on spherical or partial spherical objects that are included in the art you're working on--for example, a polished globe/part globe used as an ornament in architecture, or the plated highly reflective visor of a space suit. Even standard Christmas ornaments or brandy glasses in the foreground of a "homey" interior would be a problem without understanding it to some degree.
