What's the Easiest/Fastest Way to Draw a Square in Perspective?

that's not a square, that's a trapezoid

eyeball it

what is A and B? also that doesn't look square at all

>>2942818
just draw a square

>>2942818
blender.

also, with one point perspective you don't need to worry, as long as your 45 degrees vanishing points are consistent.

Draw an ellipse, draw a square in perspective around it.An ellipse is a circle in perspective. A circle fits perfectly into a square so the front, back and side mid-points of the square must touch the ends of the long and short axis.

The rate of convergence depends on the angle the square is viewed from. If the vanishing point is further UP from the eye-level, the convergence will be less dramatic while pointing further down makes it more dramatic.

>Easiest/Fastest Way
can't think of a more overcomplicated yet inexact way of doing it than yours.

So what are the faster methods you know? I'm not him but AFAIK this is really the fastest way without needing a complete perspective setup with VPs and MPs.

Trace it

using any 3d software. that's what that shit was invented for.

or eyeballing it, if you're going to guess those ellipses anyway.

>>2942818
It depends on the perspective, what perspective do you have in mind?

A square is arbitrary, if you say it's a square it's a square. But if the question is how to draw another square based on a give square, I dunno buddy there's tons of ways and it all depends if you want the square to be tangent, similar, congruent, on the same plane, etc.

is NOT arbitrary. with 2 or 3 vps, given 3 sides there's only one possible way of making a correct square.

>>2942818
Use the Huang Wei method. Of course.

>>2942818
get the 45 deg diagonal vp

>>2943952
If you draw the cube first to determine the VPs then it's still arbitrary. All depends on what's given first.
