How to Construct Ellipses In Perspective

[@rewguy8373]

Wow! Who knew drawing a circle could get so complicated? You are very good at explain how to do technical drawings. Thanks for the videos. I’m learning a lot.

[@DrawshStudio]

Thank you :) And you are right, circles are hard! Crazy huh? I spent a month working on these two videos because the topic is such a complicated one to get down. Happy to hear they are helping you learn :)

This should have more views, thank you for fixing every wheel I ever sketch again.

[@DrawshStudio]

Happy to help, thanks for the watch and comment!!

You are a lifesaver!!! This is so clear and useful!!!

[@DrawshStudio]

😆thank you, glad this is useful to you!!

[@jorgeriveramx]

Awesome, watched this at work and sent the link to my phone just to login on my personal account and like the video, It is that good! Thanks!

[@DrawshStudio]

Wow, I appreciate the support. Thank you!

[@AbiNomac]

I just found this channel and I’m grateful I did

[@DrawshStudio]

Grateful you are here, thanks for the support :)

[@27Pyth]

Very well done! FYI I find technique 3 by far the most straightforward... its a lot of lines but imo it's more intuitive than either technique 1 or 2.

[@sophia192]

Best video series on the entire planet. I wish I could watch your class online.

[@DrawshStudio]

Thank you! I have a patreon which has more handouts and PDFs, and hopefully someday will expand into virtual classes.

These are an awesome construction methods. Even the more elaborate second method is easily reproducible in vector software like Inkscape connecting with a polygon and symmetrically smoothing the nodes (basically obtaining a quadratic curve). However, even though the construction gives the nice elliptically looking objects at off-center positions, they are not always ideal ellipses: their axes are not always perpendicular or the minor axis would not align with the cylinder axis or pass through the original center. The matching properties of the ellipses are possible in the examples in the video, because the object goes across the horizon and/or the center line. Once the object is dropped one or two its sizes off the horizon or the center line, the ellipses become skewed. This was also confirmed in those Inkscape examples following these methods by trying to find the axes. More discussion in the comments to the previous video: kzbin.info/www/bejne/lWnWfp6AjdR-fqM

[@DrawshStudio]

Thank you for suck in depth comments, I appreciate you watching my channel :)

[@devinjansa9329]

Great video, I definitely feel MORE validated buying all those ellipse guides after watching this.

[@DrawshStudio]

Haha, yes, ellipse guides are a massive help.

[@gitajoneja1401]

Really great videos and explanations provided. Received much clarity and yet going through your various videos. Thank you for helping get a much better handle on the subject without getting overwhelmed. Wish you the best.

[@DrawshStudio]

You are welcome, I am happy this helped you understand the complicated topic :)

[@gabrielchirino-melgarejo4313]

Wow that is so revolutionary for me thank you so much. I especially love the last two methods this was so helpful now all I need is how to find a perfect square within a rectangle in perspective or even how reverse engineer a golden square or 1.5 rectangle within an existing rectangle

[@DrawshStudio]

I’m happy this was so helpful, and you are in luck because I have a video on constructing a perfect square on my channel!

[@loboone2178]

this channel is amazing!

[@DrawshStudio]

Happy to hear that, thanks for the comment :)

[@rehanmallick2601]

such a beautiful explanation..........

[@DrawshStudio]

Thank you so much, I’m happy to hear you liked the explanation. I appreciate the comment :)

[@TheRandyns]

This saved my life.

[@DrawshStudio]

Awesome! Glad you are still here :)

[@arnedirlelwy]

Awesome video!! Thank you! Could you do one for drawing ellipses in 3 point or even 5 point perspective?

[@DrawshStudio]

Thank you :). I will put those suggestions on future content ideas.

[@Hoogalindo]

You should make a video on how to calculate the ellipse arc of a pre-drawn object. It'll be useful for figuring out how to accurately draw things like flaps or hinges.

[@DrawshStudio]

Thank you, that is a topic a few people have asked about so that may end up in future content :)

[@wrong5702]

Hey, Josh, this is so useful and amazing! But I don’t know how to construct a sphere inside of a cube in perspective correctly, I would appreciate it if you could make a tutorial for this!

[@DrawshStudio]

In perspective, a sphere will just be a circle! Of course, rendering it or adding cross contours will make it appear more like a sphere.

[@wrong5702]

@@DrawshStudio Yes, how to find the radius of this circle?👀

[@DrawshStudio]

What I would do is use a grid on the ground, find the center point of the grid and draw a line up to the height of the sphere I wanted. The from the center of that line draw an equal horizontal. Then build the circle around it. The grid would be helpful to know the approximate scale of the sphere. Or use the perfect cube method in my other video and do what I just suggested in the center of that cube.

[@wrong5702]

this is awesome!!!!!!!🆒

[@DrawshStudio]

Thanks for engaging with my channel, happy you like it :)

[@ojosdeRAEH]

In fact, the minor axis does not pass through the center of the ellipse. It passes close, but not over it.

[@DrawshStudio]

Thanks for you interest in the videos :)

[@saucelessbones5872]

never knew there was such a thing as a french curve

[@DrawshStudio]

French curves are a great tool if you are working traditionally :)

[@FrancoiseMuragijimana-l8x]

How to join this point can using campas

[@jagratichaudhary9616]

Pls make a analytic video on kim jung gi drawings

[@DrawshStudio]

Thanks for the suggestion. Here’s a video of the man himself explaining what he does :) m.kzbin.info/www/bejne/jIapeJhjadBpmrc

[@HappehLemons]

I am confused on the construction. If we use the same method of basic construction for 1 or 2 point perspective, but there’s a tilt of the ellipse in 2p, wouldn’t it exist in 1p as well? You can make the exact same plane both flat on the ground and standing up, and they would have the same tangency points so you would end up constructing the same ellipse, but in your last video you said that a horizontal ellipse and a vertical one are constructed different. This is very confusing to me. Can you help me understand?

[@DrawshStudio]

It is one of the weird things about ellipses and how we perceive them. Linear perspective is an imperfect mimic of how we actually see and there are some things that we do to make them appear correct to our eyes. The plane standing vertical is perceived different than the plane laying horizontal. There is another of those distortions in flat planes as well. As they move farther to the outside of our vision, they theoretically would tip. Photographs show this as well. But when we draw them that way they look like they are lifting off the ground and not flat. So we cheat them flat to make them APPEAR correct to the drawing and our eye.

[@jotmode90]

If I take into account of the Major and Minor Axis, is that the Major Axis touches one point of tangency of a circle, while the Minor axis only touches the Center Point of the Perspective

[@DrawshStudio]

If I understand your question, I believe you are correct.

[@PeterOlsen-c2u]

The rear ellipse did not have the same visual curve on the left as the front ellipse did !? I think but then at my age some times cleat visually vertical lines seem slightly off!

[@DrawshStudio]

Ellipses can look strange sometimes.

[@BonfaLuiz]

About the last (3d) method. I made the horizon line to sit lower than perspective center point (X-trick center). The ellipse was constructed smoothly, it looks pretty natural but... I tried to draw minor and major axes and now they are tilted counterclockwise instead of clockwise shown in your diagram because the left vanishing point is now lower. Is it OK to have this weird tilt?

[@DrawshStudio]

It is hard to say for sure without seeing it, but in general, the tilt can be any angle or direction. It all depends on the perspective you have drawn it in. And often, a very small change can make a big difference as lines project out in space.

[@BonfaLuiz]

@@DrawshStudio : Well, my drawing is very similar to yours (as it looks at 6:26 time mark). And it is easily reproducible. The difference is that your horizon line is in a small distance X above the center of the panel with the ellipse but mine is the same distance X below this center approx. So the constructed ellipse looks very similar to yours but both axes on my drawing are differently tilted that is counterclockwise from vertical.

[@DrawshStudio]

Perspective is a challenge because small changes in one area can make big changes in another, especially moving a vanishing point. I wouldn’t be able to correct your drawing without seeing it unfortunately.

[@BonfaLuiz]

@@DrawshStudio : Please check your gmail.

[@DrawshStudio]

I appreciate your enthusiasm but I don’t have time in my schedule to perform online critiques. I may have that as an option through a future Patreon if there is interest.

[@nicjolas]

i'm going insane

[@DrawshStudio]

I’m right there with you.

[@JulissaDeleon-n2i]

How come he disappeared 😢

[@DrawshStudio]

These videos are incredibly labor intensive to make and do not make any revenue. So sadly I had to stop for now and take on more paying jobs :). Thanks for the interest in my teaching! I have a Patreon if you can support and hopefully will be able to expand that more in the future.

[@esausantibanez3702]

I just tried drawing an elipse in perspective (not a circle in perspective) as if this was not difficult enough. weird things happened...

[@DrawshStudio]

Be careful you don’t accidentally open a wormhole into another space time.

[@zeus-truth]

​@@DrawshStudio😂😂😂😂😂😂

[@KEP1983]

The major and minor axis doesnt make much sense. This elipse isnt symmetrical... the left side is larger than the right side. The bottom of the major axis is theoretically where the widest point of the elipse should be, but it's not. The widest point is actually where the middle of the "X" in the box is.

[@DrawshStudio]

Thanks for the interest in my videos but you actually aren’t correct here. The major and minor axis are the widest parts of the ellipse but they are shifted because it is in 2 point perspective. if you watch my other video on ellipses it will explain why.
