The cube you drew is outside the cone on vision. That is why the bottom corner looks like a spike all you have to do is make your vanishing points wider apart.

Yes of course! As I said in the beginning of the videos they aren’t perfect, nor are they meant to be. I made them as I wanted in order to convey the principles of conveying the perspective of the sphere via a cube. Real perspective vanishing points are infinite and far wider spaced apart :)

Reminds me of the scene at the beginning of the Stargate where Jackson is drawing on the board explaining how to find a point in space using six points, after he’s worked out the symbol for the point of origin for Earth. In all seriousness, geometry is definitely not my thing, but that was really helpful. Had to watch the middle section twice until my eyes adjusted and it clicked in my brain. Often I find the eye on the right hand side difficult when drawing people facing to one side slightly and I can’t get it to look right. I hadn’t thought of perspective in the sphere. Light bulb moment. If anyone wants to practice drawing lots of perspective and cubes, I recommend following draw a box. I started last year but got stuck on the 250 cube challenge. I need to start that again, as it was helping. Thanks for the video, I going to keep on drawing. Especially as my hardback copy of Loomis drawing the head and hands arrived yesterday, a great book, definitely worth getting a print copy.

Welcome to the channel! I’m glad you found this video helpful. I need to watch that scene from Stargate lol. Geometry is complex but helpful. I couldn’t agree more on drawing the second eye when the head is tilted, there’s a lot of complex anatomy that appears different depending on the angle. I have that one Loomis’ Drawing the Head and Hands and am looking forward to working from that! Happy drawing :)

A lot was covered in this video. If you break it up into ‘bite size’ pieces just practicing the initial steps until you are comfortable then move on you will more easily follow what he is teaching.

Might be quicker to connect diagonals of each face to identify their respective centers at the intersecting points, no?

Hi! Thanks for your comment. I’m not sure if I understand what you’re trying to say here.

Ok, so I have a question. And this might seem incredibly, well, dumb. But are you saying that (on the face, for example) that the "lines" created by the features all go to one vanishing point? So the "eye" line should NOT be parallel to, say, the mouth....that just like how the lines used to draw a box converge, so should the lines of the features?

Ok, your video reminded me of a Kim Jung Gi video where (I think) he's trying to explain the same thing you are...but in a slightly different way. Would love to hear what you think. My understanding of it is....basically, even the lines that make up a skull follow perspective. I think Im starting to get it. Or maybe not😂. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--5QIiubr10g.htmlsi=SF-sfRPRaahj8roj

I can see with many comments that there is a desire for a more thorough video on linear perspective and someday when I have the time to do it justice I will, but for now we are just dipping into the theory for the sake of Learning to Draw with “Fun with a Pencil”. Technically the “horizon” Depends on our eye level and where we are looking. Everything gets smaller as it is further from us in every direction. The face has symmetry and parallel properties, and depending on our viewing angle, the features closer to us appear larger and those further appear smaller, but the actual anatomy has horizontality and verticality. That’s to say that yes, in theory when the face is oriented upright, we can draw a vertical line from the midpoint between the eyes to the midpoint of the chin. And like you said the eye line is parallel to the mouth line (when we are talking about the horizontal lines that wrap around the face, like in the Loomis method). Hope that helps!

I think people need to remember the lines are created and defined by 3 dimensions and so even the eye ‘lines’ do follow perspective.
