How to draw squares and circles in perspective [Where to place vanishing points] 

Yes, you are correct. The horizontal circles are only different because I made the squares slightly different sizes😅. I didn't think things through at the the time and simply showed the result that I got by drawing the squares with the same center point but not anything else. To make them all the same size I would have to draw one square first and make a circle within it, and then base all my other squares off that circle.

You're welcome. I'm glad it helped you.

The principles in this video has helped me draw squares free hand. I do it a lot when I do quick sketches. After you do enough drawings where you take the time to find vanishing points, you will begin to start to know where approximate vanishing points will be simply by thinking about what you want. If you want to draw free hand, Imagine the location of those vanishing points, and then simply angle the edges of your square in those directions. Your square might not be perfect, but it will be pretty close. There is so many different angles a square can be drawn at, and it changes based on where that square is on the page and where your horizon line is. So there's not angles I can simply just tell you.

I haven't ever used books for drawing in perspective. There's probably some good ones out there though. I just use guides and rulers in photoshop, or a protractor and ruler if I'm drawing on real paper. Sorry I can't be of more help there. I'm glad you found this tutorial helpful!

Your comment is a year old, but if you are still interested I can give you a few recommendations. I have tons of perspective books, and I have narrowed it down to about 3 or four books that cover literally everything you need to know

I'm glad you found the video helpful! I'm not sure what you mean by three-point perspective for squares... Squares only go in two directions, so at most they will only have two vanishing points. Do you perhaps mean how to draw a cube or box? This type of shape can have three vanishing points, and I have another video on my channel that shows how to do 3-point perspective for that type of shape. Hopefully, this answers your question. If not, let me know! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VRkddGqI420.html

You're right. Since a circle doesn't have sides, it shouldn't change shape if you rotate it around like a saw blade. (I call this horizontal rotation) Drawing circles to match different horizontal square rotations will only slightly change its SIZE. When you turn a circle away from the viewer, however, it will look different depending on how it is positioned. I call this vertical rotation (Like flipping a coin around in your fingers) Only spheres will look the same at every angle.

Never mind. I think I understand what your saying. The size shouldn't change either. I think my squares must not be perfect. After all, a saw blade doesn't expand as it turns. LOL Good job on catching that.

When making an animation or star, it's probably best to make one circle and then use that as a base to make rotate squares afterward. My squares might be true squares, but I might have made some larger than others.

@@EmilysArtStudio You're right on that, the squares should follow the curve of the ellipse, this is true for any animation as they all follow the arc of an ellipse/circle. Your circles probably share the same center point in perspective but the sizes of the square varies so you ended up with very slight concentric circles (circles that radiate from a single point). I recommend checking out David Chalsea's book "Perspective for comic book artist", it goes over a lot of what you explained but also has a great chapter about ellipses/circles in perspective.

I don't think you need a math book. Probably just a protractor if you don't know what or how to draw certain angles.

It doesn't matter so much if you are only making one square. However, if you want to create an animation of a square rotating, or multiple squares with different vanishing points on the same piece of paper, then having a station point with specific angles will help you make multiple squares correlate together in the way you want.

My goal is to understand why certain steps need to be followed in order to make a cube in linear perspective. Given that we are talking about 2pt perspective, I will go along with that as the premise... I guess my question is how do we know that the "square" that is being created is truly a square and not just a rectangle?

No it's Patrick

Agree. I was not good at this in art school and I still can't find a simple way to deal with it. I'm trying to paint a birdbath with a raised smaller circular sundial in the center (on a 24x24 canvas). The angle is closest to 6:20 in this video--looking down on it from standing height. I have it going beyond the canvas edge...it's hard to figure out how to get the rim in correct perspective plus get the cast shadows from the sundial as well. I wish there was a laser drawing too that would let me shine ellipses and angled circles on the canvas! How does an artist draw vanishing points that may be many feet beyond the workspace?
