    Question Stacking objects with Multiple vanishing points

    I am trying to stack two objects together using multiple vanishing points(2) but Box A seems to be just only floating and not sitting on top of Box B.

    Help me solve my problem pls...



    the distortion of the 2 boxes are not the same too.. they looks like from 2 different image and joint together... I believe it is due to cone of vision stuff but could you guys help me make the distortion of the two objects the same?

    Thank you!

    Show me how you constructed your vanishing points?

    A and B vanishing points have the same distance.

    Looks like you accidently constructed this more or less correctly, but I suggest you construct your vanishing points from the stationary point next time. Your stationary point is too close to the horizon, which means your vanishing points are too close to each other. In other words, your drawing is supposed to be looked at from a short distance. You can verify this for yourself.

    Choose a station point below the horizon line and intersect two lines at 90 degrees to each other from this point with the horizon line for each pair of vanishing points like this (colored points and E are interactive; E is station point; both boxes are correct cubes):

    You have the right idea, all your orthogonal lines are going to their correct vanishing points! However, it looks off because the vanishing points are much too close together. You can see the angles of the boxes are less than 90 degrees in angle, which causes the unnatural looking distortion. place your vanishing points farther away from each other, still on the horizon line. Best thing to do to make sure they're far enough away, make a quick box using them, and if the angle of the box's corners are a right angle or obtuse angle, you got it! Less than 90 degrees acute angles will give that distortion.

    Does it look convincing now? I think there's still something wrong. They are still only just floating.. I still don't get where to start the surface of another box. I mean where to put it's accurate elevation.
    I keep the angles of boxed 90 degrees btw.. thanks for that. Gonna try to explore the angle stuff next time.


    I am just trying to recreate these stacks of book.

    I'm sorry if I can't follow all your instruction guys, this might take me days to digest and understand it all.

    Thank you!

    Much better, but your vanishing points are still too close together.

    Also it helps to draw with more accuracy to corner points. A couple mm can make a big difference.

    I suggest you to actually draw station point and using that 90 degrees like onemax showed, first you draw everything, then you start estimating
