Man... This student... His eyes. He has experienced some profound ordeals.

2:52 The student is truly terrifying to behold.

[@gokhank795]

Thank you for keeping Drawabox "updated"

[@Catastrophe699]

The students are so goofy, I love it 😂❤

[@stormlord1984]

Wish you had made those videos back when I started. But I am still thankful for them, I am overcoming burn out and will be returning to drawing basics again this week!

[@alexmccaleb2152]

I know I'm getting sentimental here, but new videos breaking down spatial reasoning again. It's just... Refreshing! 😎

[@Powerphail]

I love how clear and concise your explanations are. So tight and satisfying. Thanks for going in depth for us (no pun intended).

[@Zirulnikoff]

Bro, l really appreciate this videos, u stay doing a lot more easy understand this concepts in the way u explain it 🥺✨

[@conviction_amp]

me trying to understand this:

[@caswavala9624]

well, i’ll certainly have rewatch these perspective videos 😅

[@gigworktv]

Loving this course so far.

[@AdventureCJ]

I taught myself infinity last year this man taught me more I guess there are an infinite amount of thing you can learn about infinity

[@zox5370]

So glad to see new videos!!

[@Evie_Ruby]

GUYS now I've figured out why I was so confused with rotated boxes. It's because I didn't properly understand this part. Please make sure to rewatch this video after watching the rotated boxes video!

[@Evie_Ruby]

The distances between the students shrink, just as the students themselves do. The distances between the lines that represent them on the page get smaller until finally they converge to a single point. The vanishing points for edges that run parallel to the ground plane will be situated on the horizon line,

[@mayara.mp3]

Okay, now things are getting tricky.....but i'm not planning to give up >:)

[@thenamesandounts9807]

Can the student be less traumatising please?

[@Uncomfortable]

On the discord, there's a gif from when I was still rigging the character and fixing issues, where I had him twerking in order to help identify weight painting issues. Be glad you were spared from seeing that!

[@NBP722]

I'm going to dress up as the student for Halloween. Pure nightmare fuel.

[@Uncomfortable]

What a horrific idea! It would be even more vile and villainous if you were to share photos of such a costume with our discord community!

[@MrMcgee-me6bu]

im sorry, but the students running away like that made me laugh forever. that was too funny 2:31

[@RtAtelier]

You're remaking the videos... Now I have to watch them all over again.

[@Colow-uv6pk]

The student is definitely scary 😧 like why he looking at me like that

[@zox5370]

2:35 that’s fast 😳

[@arvisuria]

XD

[@Palindrome3945]

I love how the student is very scary at first but it just gets worse.

[@Namse21]

It seems arbitrary, the vanishing points we decide to consider ‘on the horizon line’ and those that arent… if we treat all the vps equally… the horizon lines can be drawn between any two points, and since they can be technically at any point at infinity from the viewer, doesnt the viewer have a ‘horizon sphere’ rather than a horizon ‘line’ or ‘circle’?

[@Uncomfortable]

Any line can be drawn between two points, that's true - but you're missing an important point. The horizon line is in practice, the infinitely distant edge *of the ground plane*. I say in practice because technically this plane's orientation (and therefore the horizon as well) is relative to the tilt of the viewer's head, but normally this is not given any sort of an angle. But regardless, that's the missing piece in your question. To reiterate the point, there is a specific plane that the horizon relates to, which eliminates the arbitrariness of which you speak. Vanishing points that sit on the horizon line govern lines that run parallel to that ground plane. Those sets of lines which slant downwards relative to the ground plane as they move away from the viewer have vanishing points below the horizon, and those that slat upwards relative to the ground plane as they move away from the viewer have vanishing points above the horizon.

Sir after drawabox do you know the best way to draw human figure anatomy gesture like any other course or any books

[@Uncomfortable]

I myself learned from an in-person class taught by Kevin Chen, but I found that Steve Huston's courses on New Masters Academy follow a very similar methodology that really helped me to better understand how to approach capturing the human figure.

Hello! I recently found out about this course and I am interested in doing the paid version with official critiques but I was wondering if this would be a good fit for someone who is interested in fine art - landscape painting, to be exact. Seems that most people taking the course are doing it for illustration & concept art. I would assume that fundamentals should be the same for everyone but just to double check - is this a good start for someone embarking on a lanscape-painting-learning-journey?

[@fsandraungureanu97]

It definitely is

[@rubyc8178]

How can I make blender look like this? with the specific wireframe, and colors.

[@Uncomfortable]

I'm pretty sure I wasn't doing it in the best way, so it was a big pain in the butt - but mostly it was a combination of toon shading and lineart modifiers (although it's been a while and I don't use blender often enough to remember the specifics). Whatever I was doing also seemed to piss Blender off, as it crashed constantly while I was making this.

[@verycherryberry3752]

bro that student is the stuff of horror movies

[@Uncomfortable]

Just wait until you see it looking back at you in the mirror!

[@onikemango]

This student triggered some of my visual phobias, even before the dots! I have a fear of semi-formed humanoid things (gingerbread man from Shrek, Michelin man). Despite being hard for me to tolerate, another great lesson!

[@caswavala9624]

1:27 i don’t really get it, how can further end be wider, if it shrinks?

[@caswavala9624]

Ohh.. i get it now, but boxes example is a little confusing. Because that box in kinda shifted, and is going farther back, so i expected it to be not so much wider?Or is that box actually titled inwards, and that’s why?i understand with flat ellipses

[@Uncomfortable]

@@caswavala9624 This concept is easier to understand in the context of ellipses/cylinders, which you can watch here: kzbin.info/www/bejne/qnmtZKWwoJuepNE , and which is also explained here: drawabox.com/lesson/1/5/degreeshift To answer your initial question though, it's possible for something to be smaller in its overall scale (where the whole object appears smaller while maintaining its original proportions), and then to have the actual proportions - its width relative to its height - change. That's what's happening here. Perspective demands that the far end gets smaller overall, but the difference in the angle at which one end is being viewed relative to the other (as shown in the "degree shift" notes I linked above) causes the proportions to get skewed relative to one another.

[@HyperfixationStation]

[@Markus-_-]

Hello Irshad, can you make a complete video about Ortho views and XYZ? I've watched your past videos with ortho, but felt like I need more in depth tutorial on the subject with "Why, and How" XYZ axis and sections, and Planes, and how to rotate it at any angle we want. Orthograpic projection, and all the 6 possible views. front top bottom left right rear I really want to learn and master and understand orthograpic views, sometimes feng zhu's works using multiple combinations of ortho views including the rear and bottom, before transfering them into perspective.. thank you very much

[@Soco_oh]

There are some more explanations on orthographic and technical perspective drawing in lessons 6 and 7

[@Markus-_-]

@@Soco_oh Thank you bro.. I'm gonna check it..

[@Uncomfortable]

So I'm guessing you've now taken a look at this section at Soco's recommendation: drawabox.com/lesson/6/1/orthographics . What I did want to mention however is that as explained in the video that comes just before this one ( kzbin.info/www/bejne/jpmniJyGdreiq7s ), Drawabox isn't meant to be a full perspective course. There are definitely places where we get into more technical perspective (like Lesson 6), but beyond what's explained there, what you're asking for is likely outside of the scope of this course. Everything we teach here is relevant to developing students' underlying spatial reasoning skills, so there are definitely a lot of perspective concepts that we don't dig into, simply because that's not our goal.

[@o0shivashakti0o]

These are small, but the ones out there are far away

[@verycherryberry3752]

exactly what i was thinking lol

[@AdventureCJ]

This leaves me whith a question what is the theoretical human render distance cap as in not of the matter that your brain would crash as in you would not even see the object anymore as light may travel so far and it will reach us is there a theoretical render distance?

[@Uncomfortable]

It's subject to the medium through which light is passing to reach your eyes - meaning, when you're on dry land looking around, light is passing through air and that air is causing the light to scatter more and more as the distance it has to travel increases. This results in a concept known as "atmospheric perspective" (also known as aerial perspective), where the farther something is from the viewer, the less contrast it has. Fog creates an exaggerated sense of this, because the air has far more water particles in it to diffuse that light. It does depend on what you're looking through though - looking around underwater is going to limit how far you can see by quite a bit, whereas if you're out in space, I'd expect you'd be able to see very far.

[@annaruru6974]

Theres a thing I dont understand why when we look ay the cylinder we see te second circle away from us is wider but in the vídeo says when they go farther away its smaller then why in the cylinder is not the same? Its because cylinder case is degree shift and in the other case its scale shift?

[@Uncomfortable]

Both can be true simultaneously, you just have to be very specific with your definitions. The overall scale of the farther end is smaller, but the proportions are different causing that farther end to appear wider.

[@annaruru6974]

@@Uncomfortable but in case of the cylinder, it has the same proportions, why it's wider the farthest circle face?

[@Uncomfortable]

@@annaruru6974 You're misunderstanding me. The two cases are identical. In *both* cases, the farther end is proportionally wider in one dimension, but overall still smaller. So for the cylinder, the ellipse on the other end would be smaller overall (because the side edges of the cylinder are converging, so the distance between them closer to the viewer would be greater, and the distance between them on the farther end would be smaller), despite being wider in one dimension. One thing that might help in understanding how they are identical is if you envision the cylinder as though it had a box constructed around it.

[@annaruru6974]

@@Uncomfortable ty for explaning

[@HyperfixationStation]

@@Uncomfortable in theory I think I understand now, but visually like at 1:19, the cylinder in the bottom right looks like both the top and bottom ellipses are identical... is it just me? The bottom doesn't look smaller at all, or wider

This is confusing

[@Uncomfortable]

That's okay - sometimes the lecture material will make sense, sometimes (and perhaps more often) it won't quite fit together right. Just remember that the lecture material is there to give you context, but ultimately the learning and understanding is achieved by doing the exercises to the best of your current ability (in order to demonstrate which parts you do grasp, and which you don't), and then getting feedback by a third party to catch anything that you might not be grasping properly.
