# How to draw perfect square in perspective?

 08 August 2013 Defonten Vault Dweller   portfolio Natiq Aghayev Senior 3D Artist Prague, Czech Republic How to draw perfect square in perspective? Hi, the reason I'm asking - it is a well known fact that to draw a perfect circle in perspective - it has to be drawn inside a perfect square. And if your square is actually a rectangle rather than a square - you'll end up drawing an ellipse in perspective and not a circle.. So, the question is - how do I know that I'm drawing a perfect square? I can't find the answer - be it in Photoshop or on a paper. Pleas help! share quote

But instead, you would use the tools available to you to make that circle. If it was paper, you should use a compass, or at least a ruler to draw out the four sides then create a grid to where you can draw approximately the circle, or get a hemispherical ruler to draw it. If you're in Photoshop, use the circle lasso tool and hold SHIFT to make it a perfect square. You can also drag out ruler guides on all four sides, and use a lasso tool to again draw the perfect square bound within those guide lines. You can then transform that, and warp it to whatever perspective you want for your painting. __________________ David Luong www.davidluong.net facebook.com/ackdoh I teach a DMP Workshop share quote

A perfect circle in perspective is a sphere, right? That, or like an alternative version of "Tool". Either way, I think the answer is: Maya Just to save time, right?!? If you want to work it out in 2D, it depends on the angle because that determines the foreshortening. So, the expression "in perspective" is rather general. I actually use the line tool and create really old fashioned grids to work out perspective in my DMPs all the time. However, I'm sure Google can offer some basic perspective tutorials and video. __________________ I'm making a movie!! share quote
 08 August 2013 Defonten Vault Dweller   portfolio Natiq Aghayev Senior 3D Artist Prague, Czech Republic Ackdoh, Milanschere Thanks for replying! But I think I wasn't clear enough about what I mean. I of course can draw a perfect circle and a perfect square on a flat surface both in PS and on paper. I'm only having problems with drawing it in perspective. Let's for a moment forget about circle. Lets say I want to draw a Cube hanging in the air on a 2-point perspective. How do I know that I'm drawing an absolutely equal on all sides Cube? I've attached an example of what I'm saying. Simply put, I'm not absolutely sure where to place those red lines for it to be a perfect cube. Thanks! Of course I can place them approximately, but anyways, I wanted to know if there's a mean to draw a perfect cube or square anywhere on a 2 point perspective. share quote

Learnt so much about perspective I bought the entire set. Its a simple trick to get a perfect square in perspective, if look at how Gary does it makes sense. I often rewatch these time and time again, also I am going to put the video through my edit software and metadata important parts. David Mattingly book has a wonderful section on perspective also. not much help but can push you in the right direction Richie __________________ Rockhopper VFX @Rockhoppermedia share quote

 12 December 2013 arpace New Member Anthony Pace Canada I made a video earlier this year that shows how to find the station point, the measuring points, and of course, how to draw a perfect cube in 2pt perspective. You can find the video here: http://www.youtube.com/watch?v=OB3UEpxFlj8 I use illustrator for the demo, but if doing it on paper you just need a ruler and a pencil. A compass and a triangle like a 30/60/90 or a 45/45/90 would make things easier; however, it's still quite doable without them. __________________ Some old stuff I need to update: http://anthony-pace.deviantart.com share quote
