Crash-Course: Curvilinear Perspective part 2 - Five-Point Perspective

[@trigestigro4707]

0:51 Mindblowing. I didn't know this way to use 4 points perspective.

[@edwardjones8249]

Doing photography for five years makes this very familiar. Reminds me of a fisheye lens. Awesome 👍

[@Jasoncm]

I studied fisheye photography a TON when I was first learning curvilinear drawing.

[@TiffanyNg100]

love this! such a well rxpalin bidoe for difficult topic

[@panchochompa]

Thanks! Good explanation, I really learned

[@3govideo]

Thank you! Amazing! I’m a 360 photographer but never thought of this. Thank you very much!

[@Jasoncm]

Oh yeah, this viewpoint should look REALLY familiar to you, then!

[@danrojas]

Fascinating! That must be how Escher created his drawings! Thanks!

[@Jasoncm]

One of many approaches he used, yes!

[@mrchristian8782]

this is very informative thank you!

[@JoJoboiWav]

Interesting, thank you

[@illiria2000]

I love your videos! Is it possible to make more videos on 5 point perspective? For example if you need to draw something that’s a specific angle?

[@Jasoncm]

Maybe so! What sort of thing did you have in mind?

[@illiria2000]

What I had in mind was, knowing how to draw something that’s 60° and 30° on the horizontal line for example, or how to draw things that are inclined and rotated while all in 5 point perspective. Is that something you can help us out with? It would be greatly appreciate. Thank you.

[@Jasoncm]

@@illiria2000 that's a great idea. I'll put it on my to-do list.

[@andresandres7267]

Thank you

[@TiKayStyle]

How many perspective systems exist? I am looking for atypical/psychedelic views.

[@Jasoncm]

Ooh, that's hard to answer, it sort of depends on where you want to draw the lines. I tend to think of it as there is basic rectilinear perspective (1 pt, 2pt, 3pt) and basic curvilinear (4pt, 5pt, 6 pt) and then I think of the weird stuff, where you have repeating vanishing points (where multiple VP's represent the same direction) or the lines connect the vp's in s-curves or whatever as just one category called "Other." Oh, and then there's perspective drawn onto non-flat surfaces, that's another category (drawing on a sphere or curve, or faceted surfaces). It kind of keeps going. I'm afraid I don't have good google-search terms to give you once you get past 6 point.

[@TiKayStyle]

@@Jasoncm wow thanks for so many informationa. Yes I am a mathematican and thought about it the last days. You can also draw one point for two opposide directions (North&South, West&East) and connect them with a circle. Spiral, eliptic and my favorite: inside out. Drawing a House/Body with Perspective, as if you are inside the thing but paint it with the texture from outside. I will gather some sketches and could link them here, if you want.

[@Jasoncm]

@@TiKayStyle sure, I'd love to see it.

[@shaf7643]

great video, many thanks. What is the compass that you are using? Many thanks

[@Jasoncm]

It's a beam compass made by Alvin. I believe the model is marketed as "Alvin Speed-set beam compass"

[@fartestry5522]

Please make 6 point perspective video

[@Jasoncm]

It's in the works! (Actually, THEY are in the works, I think I'll break it into 3 videos)

[@fartestry5522]

@@Jasoncm thank you I’ve been trying to look everywhere for a concrete tutorial on 6 point perspective and not many people know about it lol

[@dinococe]

where did you buy that nice compas?

[@Jasoncm]

It's been so many years I don't remember and it's irrelevant. But if you google "Beam Compass" you'll find some suppliers.

[@doctirdaddy4876]

what if you add another vanishing point does that new object keep the vertical curvature? whats that called?

[@Jasoncm]

I think you're looking for five-point perspective? -- kzbin.info/www/bejne/nZXaeZRjZah7bc0

[@doctirdaddy4876]

@@Jasoncm thats the video we are on. but how do we add another vanishing point. what if we want something rotated in a degree that does not align with the 3 on the horizon, how do you add another horizon point while keeping the verticality of the 2 vertical vanishing points. i hope it makes sense, i wish i could draw it, that would articulate what im trying to express a lot easier.

[@Jasoncm]

@@doctirdaddy4876 oops! So sorry about that. So what you're looking for is inside a 5-pt drawing system, how do you draw a new object that doesn't align with the main system except for the verticals. Like if you were drawing a table with chairs around it and wanted one of the chairs to be rotated away from the table. Is that right?

[@anuplonkar2198]

2 point perspective is difficult to me after watching this 4 point I think 2 point is not that difficult

[@Jasoncm]

I think a key to keep in mind when drawing in 2 point is that your vanishing points represent directions, not places. So if you've got a box that faces north-south, any line on the box that points north-south will point at one vanishing point, and any line that points east-west will point at the other. And then up and down just stays up and down on the paper.

[@srivathsm9887]

can you please make videos about curvilinear 2 point and 3 point perspectives? I'm searching this topic but cannot find any resources

[@Jasoncm]

Some of that might be a semantics problem. The names for these systems aren't as set-in-stone as rectilinear perspective systems are. For the way _I_ name things, 1-point curvilinear perspective would be 5-point perspective, 2-point would be four point, and 3-point would be six-point. If you can tell me in more detail what you're looking for, maybe I can help.

​@@Jasoncm www.researchgate.net/publication/315799546_Curvilinear_perspective_how_to_draw_and_examples i wanna know how to project objects in 2 point and 3 point onto hemispherical field of view. (according to the above article). thanks for replying! also is there any other way i contact you and follow your work? im so greatful for your videos (i dont completely understand the article very well maybe you know what its about and can maybe make a video about it!)
