The Impossible Box Perspective

Some common perspective mistakes are easy to fix! Let's talk about cylinders and cubes.

[@prah_da_g]

This was so helpful. Perspective gives me so much trouble

[@Medic576]

Yeah, same

[@user-ph9pm6fc7g]

yeah, this video really gave me so much perspective

[@You-ph5wc]

Sameeeeee

[@Ibloop]

Literally use your eyes

[@lachlanhenry486]

Good thing you don't have to use it in art then, right? Learning more about stuff we don't like is dangerous. At most these skills are good to remember the existence of. If someone can understand that what you drew is a cup, that's it. Then you can make it a fun to look at cup. You're the one making it.

[@Archael07]

the engineer in me is screaming at the 2nd half😂

[@user-ph9pm6fc7g]

i scream whenever i see oblique

[@AzeroRed]

First of all it’s not even an isometric view!!! Second there is a reason we keep perspective view off

[@biblicallyaccurateangel2476]

[@AzeroRed]

@@biblicallyaccurateangel2476 yeah but wrt engineering drawings it hurts

[@Sgt.Bones181]

@@biblicallyaccurateangel2476 Just saying, not architecture, engineering. Engineers need the designs made in a standardized way so other engineers can understand them. Architects don't care if engineers can understand their work

[@martinmnagell2894]

As an engineering student, I see the box one as an absolute loss.

[@satibel]

parallel (cabinet or cavalier) vs perspective view (1-3 point) cabinet and cavalier views are useful if you're trying to make medieval drawings, as they mostly use that. currently military and iso are the most used parallel projections, with military having the advantage of the cavalier perspective of conserving angles on 2 faces, but it does it on the floor instead of the face. and isometric has the advantage of keeping lengths for all side (and imo looking better).

[@littlebigbiddy]

Imagine looking at the street from atop a skyscraper with other buildings around. The buildings taper off from your perspective. Parallel lines aren’t parallel in our vision. If you drew 2 lines parallel a foot apart stretching to infinity in either direction, they would look like they converged if you looked towards either infinity.

The "wrong" cube was actually drawn correctly, just it was drawn in isometric projection

[@Ali_art]

Point perspective. Yes isometric is a flat view

[@heydrianluisanilao1757]

That's oblique, not isometric

[@sillycheese301]

He never said it was wrong. It's just not dynamica

[@obama7792]

pin point the time stamp where proko says the box is wrong? he says if you want them to have depths dont draw the edges parallel. the first one isnt wrong, but it looks flat and not dynamic and the video talks about perspective in art

[@interbeamproductions]

@@obama7792the only exception is isometric cubes, because the distances between vertices are the same

As an engineer I'm disappointed and my day is ruined. You've made an unparalleled cube

[@ProkoTV]

Proud of you haha

[@protion_2312]

Mechanical engineering student here, I feel you

[@sandman4510]

As an engineer in training and novice artist, I am confused.

[@ProkoTV]

@@sandman4510 I'm pretty sure they're just making a joke about us making the sides no longer parallel and the idea of "unparalleled" being a good thing .

[@nimeshpoudel8277]

Engineering student here but I don't feel anything though I already studied engineering drawing

[@bettyowo]

The different perspectives he describes in this video are: - Oblique, aka the "parallel lines" one. Projected lines are at 45° from vertical and horizontal lines. - Three point perspective, aka where the lines turn towards each other to convey depth better. Here, vertical lines are projected from a single point below (or above, depending on the angle you view the object at) the horizon. Horizontal lines are projected towards the respective 2 points that lie on opposite sides of the horizon.

[@tocide]

Drawing perspective with a camera lens in mind would work with all of that 3d to 2d projection techniques

[@SayAhh]

My brain: "that's a crooked box!"

[@nuyabuisness7526]

I'm an engineering student and very much not artistic. Learning how to do basic 2 point perspective drawing is a lifesaver.

[@IR-O-IN-I-IN]

When it comes to drawing cubes - there's a special name for a perspective where all the lines are parallel - it's axonometry which is basically a perspective with no depth. Also - to draw a cube in a human eye perspective you have to draw a horizon on the paper so you know how steep the angles between the ledges of the cube are (I know what I'm talking about, I've been an artist for about 8 years now)

[@pnutdraws]

well the parallel lines thing depends on the type of mood/lens that would affect the object, if you lose a wider lens the more it will converge but if you use a telephoto lens or look at things in a orthographic view, there will be very less foreshortening, very parallel lines

[@justaway_of_the_samurai]

Yes but the human eye naturally has non-orthographic perspective on objects we see in the real world. So that level of perspective would be the default unless you were trying to simulate a specific camera effect.

[@pnutdraws]

@@justaway_of_the_samurai not entirely, when you look at things really far away, and you want to draw just a cropped picture of that, those things are gonna have very less foreshortening, similar to a telephoto lense, also people like to draw in different perspectives, look at all the art people make, its not just how the human eye sees, so understanding how those different perspectives works will help you with that

[@CarNerd7]

That's a niche application, Usually everything in 3D space as we see it converges. Ofcourse there are different types of perspective such as Fish eye and stuff, but the basic rules of perspective always apply and that is what the point of the Video is, basic perspective.

[@lightdark4340]

Actually in orthographic, nothing converge, no foreshortening. Therefore objects stay the same size no matter how far you move them away.

[@pnutdraws]

@@lightdark4340 yea i was using them both in an example along with telephoto lens, in orthographic perspective there is no for foreshortening

[@llkurofoxll1013]

subtle yet very dynamic.

[@KiemPlant]

I don't draw often, but when you drew the initial line I was like: that won't work because that's way too sharp if you would continue the circle. Didn't realize that was what the video's about lol.

[@ShanviGhimire-e8y]

As a beginner artist this helped me a lot , thanks 😊

[@deathawakener]

The box portion would depend on where youre looking at the box

[@rhiannonkleppang7510]

I have been drawing since I was very little. I consider myself a pretty good artist and I have done so many art classes and mentorship’s. This is my first time hearing this and it is SO useful. Will be remembering this every time I draw this stuff now. Sometimes the most obvious concept takes the longest to learn.

[@SplitxHeart]

Curves and circles are my favourite "self-assults" because I will draw them over and over and over and over... Boxes? Ah yes... the thing that nearly killed me in school, because I had to work against my artistic brain to draw "correct" geometric figures in math and for GOOOOD I was about to eat my fcking papers.

[@nameq]

why quotes? they were 100% correct in orthographic projection

[@nativenugget]

Ahahaha 😂

[@FindingYaya]

As an engineer and an artist, I’m chillin. I learned something, thank you!

[@RiccardoBernardi-h7v]

The reason we draw the cube's lines parallel is because that is called a cavalier projection Where the X and Y axes are perpendicular and the Z axis is 45° from the Y axis

[@neeevirus]

One thing I figured out was that its just best to draw an oval that wraps around a shape, it also lets you decide whether you want that 3d shape to be facing upwards or downwards by choosing which overlap to erasd

[@itsgonnabeanaurfromme]

Just decide it before drawing. It should have been part of the composition in the first place.

[@neeevirus]

@@itsgonnabeanaurfromme in hindsight you do have a valid point I personally still prefer to draw the whole thing to prevent the mistake mentioned in the short

[@VL-Secondary]

That's a good way to think about it.

Thankyou!! You explained it in a way I can understand clearly. My drawing teacher should watch this lol.

[@thenwshan]

The cup thing was mind-blowing

[@mrreemann3739]

These were insightful tips. I usually draw the box with parallel lines but you're making a lot of sense here. 😮

[@BlazinMation]

I’ve already got the curve part down but I am very thankful for the information on the cubes 👍

[@Brick_Eater_]

Your advice is unparalleled

[@hyperzhigh]

i have been having a lot of problems when drawing perspective, rly needed this, thank you

[@SmooviesTV]

Box example: This is one-point perspective vs 3-point perspective. They both have their uses

[@Zhuzhalka76]

Isn’t the first cube orthographic

[@rifolas]

Honestly this has solved like 50% of my drawing issues

[@AnimeByTheHour]

When you’re curving around a cylinder, the line should match the oval on top/bottom. To make it easier, you can just draw another oval and erase the back half.

[@zubest4250]

Never thought about boxes in that way, thanks!

[@wintershock]

There’s two conflicting parts of me right now. As an engineering student I want to cry but as an artist I think these tips can be helpful for perspective. I mostly want to cry though.

[@christiantrejos1284]

the cube explanation was way more complicated that it needed to be

[@ProkoTV]

Understandable! We weren't trying to explain how to use three points perspective here. It was an experience in reverse-engineering perspective into that classic cube drawing. If people want an actual perspective lesson, we have a bunch of shirts and longer videos on the topic, though!

[@Maninawig]

Ah yes, here we see the visual illusionist showing some of his craft.

[@munduschungus]

Took me a week to fully understand how the lines in boxes converge. I had to learn perspectives and stuff, turned out really useful later.

[@jordanprado4798]

We're used to isometric drawings of cubes, that's why we naturally draw it like that. I'm so used to it that I never thought it could be better!

[@AkISerge]

This is one of those tricks that need to be known

[@yondaOfficial]

Always good to see a new perspective

[@jarlbalgruufthegreater1758]

I had a famous artist as an art teacher in gymnasium Bunda János and he made us draw cubes for 4 years. We learnt a lot about shadows and depths, but we didnt know. I just realised it.

[@HollowQuest_KoseiZero]

Posting things one would learn in art school is so useful for inspiring artists who can't afford it.

[@Rainxiety]

The cup one was something I never considered so thank you for that! I think the box one is just a different angle or FOV, tho it does look better if you're going for an alice in wonderland feel

[@tignarita]

woah I never knew not to make the line parallel, super useful!

[@duner2028]

Ohmygod that last tip helped me so much with perspective

[@quintilleroni3242]

omg I was having trouble drawing a trash can n this helped me so muchhh

[@-Sean_]

This video gave me a new perspective on illustration

[@skulkingshadow]

To make correct perpective based parallel lines use a long ruler/scale and the lines should meet at one point, this is useful for multiple parallel lines like for hallways,table, slits in a locker or any place with parallel lines and makes things easier!

[@smarchitects26]

Must say, helpful video. And to add, It all depends on the kind of perspective you are trying to achieve.

[@djmatt18000]

Feels like a video form 2015 in a KZbin short amazing

[@nerdmuffin4439]

It's sometimes helps to try to replicate the top circle of the cup to where the fluid line is to get a better wrapping curve as well

[@llamazilla8712]

Ok actually that second tip was genuinely helpful

[@TheLORD_Y]

Yeah, the thing that ypu explained for the box is really helpful when you learn to make drawings with cubistic objects that you will later shade.

[@ithinklikeawesome]

This gives me so much perspective

[@apersonkazoo]

Thanks for teaching me how to draw a box

[@zmia_gp6189]

That… actually makes great sense, thank you!!!

[@lars7935]

This really adds some perspective

[@bsodcat]

That dynamic shape also cannot be forgotten is due to the curve of the eye’s contour as a flat camera would see a less intense version of this, you can experiment with pictures of this by purchasing vastly extreme lenses both flatter and more contour.

[@equesdeventusoccasus]

On cylinders, I match the curve of the ellipse on the top the whole way down. On cones, if the lowest point of the cross-contour line is towards the small end the curve gets more acute as it gets smaller. The curve gets more obtuse going towards the large end.

[@sisi7304]

The cylinder one is essential when drawing liquids, particularly water, in (often cylindrical) containers because the meniscus does curve up slightly at the edges compared to the center

[@SlyceDFI]

perspective vs. orthogonal projection 🔥

[@IndiHeads-mn4kq]

When making a cube you want to be able to name the points in the back as well to solve the qustion

[@jasper1064]

I needed that cylinder one that was so helpful

[@Man_of_Tears]

Tip: when drawing a cup, draw a full circle for the top as in the video. You'll get the right curveture down.

[@alexjustalexyt1144]

When I watch these it makes me realize how basic math principles help to understand these type of things. Like with the cup, the curve shouldn't be flatter or have more of a curve than the curve that is at the top or the bottom because it's simply impossible. Assuming that both ends of the cups and the line in the middle are all perpindicular.

[@hunter1586]

with the contour lines on the cylinder if you're drawing it from a lower angle the contour line will appear shorter and with less curve than a a perspective from a higher angle would

[@theothermissing_sock]

This short came at the perfect time

[@oopsie3415]

I don't know how this just came to me. Today I woke up thinking about the box thing. And I'm looking right at it

[@9767Music]

I never knew that with cylinders. Thanks a lot!

[@ameisweirdx]

To make the box thing easier: Draw a Y, acting as the frontmost top corner, you can make tje top two lines whatwver angle you want. Add all the vertical lines in parallel. Then add your lines that create the bottom of the box fronts, making them taper in towards the "back" of the box, then add the top two lines rhat finish the top panel the same way. Doing it in that order makes it SO much easier to visualise how you're consteuxting the perspective, instead of thinking of it as 3 panels you're thinking of the angles of the lines.

[@asdfghyter]

for more precision, you can use 1, 2 or 3 point perspective. for two point perspective, choose 2 points to the sides of your paper, then all lines parallel to one axis should converge to the first point and all points parallel to the other axis should converge to the second point. the vertical axis would be parallel to the paper and you would draw those lines as parallel

[@cyborgvison2024]

I was taught in engineering that you draw either 1, or 2 dots at some point on a line at the top of a page, and draw the sketches so that all the lines that go in that general direct go towards that dot

[@ProkoTV]

Those are 1 point and 2 point perspectives. Great simple perspective methods!

Dammn i hope i had discovered this video way earlier like back in primary school so that i would have flexed my drawing skills much better.

[@Xyzeuse]

Bro this was actually so helpful

[@kuobah]

I mean. The box should be drawn with the right perspective according to what you need. Like if it's in the middle of your horizon line then the sides would be pretty much parallel. Or if you're drawing something like a background for a show w a very simplified style
