- How To Set Up a PERFECT View in PERSPECTIVE - NO DISTORTION (Cone of Vision Tutorial)
In this epsidoe of draw talk we have a short tutorial that ties into the on going perspective drawing tutorials on the channel. Here I cover how to strategically set up and plan a drawing in perspective. Using the picture plane, cone of vision, vanishing points and horizon line. This method of almost working backwards, allows you to create a perfect view and locate where to place the vanishing points with no distortion in the drawing. Its especially useful for accurate design work.

I must have a very low IQ coz I'm not getting it... AT ALL!!
Same here!
Always happy to see you upload
I really love this video. I always have a hard time trying to figure out where the horizon line and the vanishing points should be and this method really makes my work easier.
Clearest explanation I've seen. Thank you.
You just answered me an old question.That is so much comforting to me ! Big thanks :D !
This was what I was searching for.
I actually wanted at what angles should my vanishing point be
Thanks for the video brother ,👍

So precise and simple, You've explained it better than my professor
Wow - I finally get it!
Thnk yu so much for your videos they are truly inspiring 😇
Thank you very much
Happy to see you
Really useful 😀
explained better than any other channels in the TH-cam
Terribly good instruction! Succinct but inclusive.
thanks for explaining its like scott robertson perspective drawing.
awesome !
Ah so it's use is to prevent distortion.
Very interesting. Thanks for the good explanation! :)
Your awesome dude
Thank you so much >^^
Thanks alot
Your amazing my gangsta
This makes sense to me when i read the book 'Perspective made easy' and some early chapters from Scott Robertson's book.
Thanks 👍
Awesome tutorial! Definitely cleared some things up. However I do have a question. How does this method work out with finding the location of the station point if the horizon line isn't on the canvas?
Your video is useful
very didactic, thank you. Julio Lucero, Astoria, NY
Wow 😮 this is where art and geometry get married, eh? Lol. Love it! Thank once again Dan. You are a great teacher 👨🏫
Katie, I did terrible in math, but want to draw realistically. After watching this, I think I'm in trouble.lol
Good class
Nice video
This was awesome! I have never heard of this thank you for the lesson.
Mate. This is so fucking good. I've got "How to Draw", but found it a little confusing. managed to get through the exercise. But this is just what i needed to make sure i've been on the right track. Thanks for the video bro!
thank you. this is very helpful. but may I know where is the best place to put the third vanishing point if drawing in three point perspective?
22nd comment 😂 good job man ur an inspairation to me👊👊
this does only work when you are looking parallel to the ground. but thanks for sharing this approach!
Can you show your A Level project, I don't know what to do for mine and I'm more of a drawer like you
I've got a question Dan, objects get their own vanishing points when they're rotating and not at the same angle as the primary vanishing points right? What would happen to those objects that are outside the cone of vision but have their own Vanishing point because they're rotated?
Hey what is the song at the end of the video ? Also, is it possible to do this free handed? Thanks for the video :D

where you got your ruler which you use?please tell
this is like drawing is engineering :)
How do you determine the standpoint? The angle of vision cone is depending closely this standpoint. Please help to clarify. Thank you.
How exactly do you determine the station point? Should its lines always be conncected where cone of vision and horison line cross? And what if i want a different angle? Could you please explain that topic in depth? I've been searching for this all over the internet and found no answer.
which hardness of pencil you use?
Hello!! This is really great !! Could you tell me how you decide the size of the COV around your picture plane? An then are there some rules to place the station point? I feel it’s a bit arbitrarily but I’m sure there is a reason to that madness lol
This is a late response but I believe the size of the COV is just fitting the picture plane inside, and the station point location is: So just draw a long line down from the horizon line where you want your cone of vision to be around, and then drag a long line down (like in the video). Then where the cone of vision meets the horizon line, draw a 60 degree line until it hits the station point line thing you drew. And then the point where it hits is the station point, and you can erase the rest of the line if you drew too long.
Not sure if this is right, but it's just what my mind came up with it and it sorta made sense. Were you able to figure it out?
Also late reply, but here we go: the angle of the cone can be set as 60° to approach human cone of vision. The circle is the base of the cone, perpendicular to the direction in wich the scene is being observed. Since the sides of the cone are subject to the angle we've set for its tip (60°), that means we can draw a triangle comprising those diagonals and the diameter of the base of the cone. Since the sum of the internal angles of every triangle is always 180° and this seems to be, at least, a isosceles triangle, we can do 180 = 60 - 2x, wich gives us 60° as a result (could also be inferred as 60 * 3 = 180). Then we can measure a 60° angle downwards from the intersection of the circle with the horizon line on both sides of this circle, and it'll point us to where the station point should be located.
You typically use 60 degrees because this is a good approximation of human vision.
@dan beardshaw when the focal point is not the center, how do you know where to set the compass and where the line ends at the station point? when the focal point is the center of the picture plane, I set the compass so the circle touches all 4 corners of the picture plane. If focal point is not the center of the picture plane, which point of the picture plane do I start with to set my circle so that all 4 corners are in the circle?
Hi Patty - I'll have a go at answering. Just imagine the circle is where the cone of your vision crosses the imaginary picture plane - the piece of glass standing somewhere in front of you onto which the image will be projected. As you move further away from the PP, the cone will get bigger, closer will make it smaller. If you're not in the middle and you want to include the whole image (the box into which the image will be drawn) inside your cone of vision, in real life you'd have to move back further. It's just like taking a photo - if you can't fit everyone in, you either get your subjects to squeeze closer, or you have to get further away from them. The 60 degree cone will naturally place you further back the bigger the circle.
So in answer to your question, if you choose the point of the PP furtherest away from the focal point, the whole PP will be inside your cone and be less distorted. This means you will have virtually stepped further away from the subject and it will all be inside your 60 deg field of vision. If you make the circle smaller, you are standing closer and more parts of the image are likely to be distorted as they will now lie outside your 60 degree cone of vision.
I hope this helps. As a photographer I'm constantly doing this with my cameras. If I have a wide angle lens (perhaps with a cone of vision of 120 degrees), I can stand much closer to my subject than if I have a zoom lens, with a much lower cone of vision. Cheers from Sydney - Dave
How do u know how much to drag the line down the focus point? How much do I know station point is down?
How do you get the radius circle?
The central focus point always have to be in the Horizon line?
this is great but why did you draw RVP on the left side and the LVP on the right side also why did you swap the angles between the RVP and the LVP in the 60 30 degree angles
How do I use this concept when I look at my subject of study directly? Is it only useful for planning and designing?
I dont think u need to use this concept when u draw directly from life, since what u see is already inside ur cone of vision
Aweomse but I have quite a few questions. Why are VP's set at 90 degree angle?
Is there any difference at all with the cone of vision (be it 90 or 60, since all that matters is the canvas to be inside cone)? I mean I can just scale the canvas and have its edges touch the circle right on the edge. Same could be done with 90 and 60? Or the vanishing points for 90 COV will be at different angle?
Cone of vision sounds more like something from get smart but yes great tutorial !
It's stricly necessary to take measurements with a compass? i mean, can i still drawing using the technique withouh being 100% precise ?
Hey, I have a question. That means no vanishing points should appear in any drawing, right? However, in some city drawings, I can see escape points in the drawaing. There's no deterioration. So how do I draw a cityscape where the escape points are in the picture but still don't deteriorate?
No? One point perspective would suggest at least one can be in the picture plane.
Thanks for the video, I have a few questions though.
A protractor is essential to start using this method? And what diameter should you use to draw the cone of vision?
Basically, you want your whole picture plane to be inside the cone. You'd use the distance from the central vanishing point to the farthest corner of the picture plane and use that as the radius. Your circle/ cone would touch the picture plane on that corner and the rest of the plane would be inside.
The protractor is necessary only if you're being very technical and trying to draw objects that are rotated at a specific angle to the observer/ station point. If you don't need that angle and simply want to accurately draw a box at some arbitrary rotation, then you can simply put the point of any right-angled object on the station point and mark where it's edges would cross the horizon line to get a set of vanishing points. A sheet of paper or a book or something would work.
Note that the protractor also has the advantage of being able to give you accurate projections of objects not composed of right angles. If you were trying to draw two planes in perspective that came to a 30 degree angle, like say the Flatiron Building, you could extend a 30 degree angle out from the station point to give you accurate vanishing points, and that would be much easier with a protractor.
Thanks for the helpful response!
I was wondering how would you do that in digitally? How do I determine 60degree Cone of Vision in that medium?
I know this is 2 years late, but for anyone else you just need to get a transparent PNG image of a protractor
I've taken many illustration classes in college, and we've done a lot of perspective and mechanical drawing, but one thing they've never taught is how to do multiple, accurate perspectives, for example let's say the image is a city landscape with a helicopter flying towards the plane of view, but from a different perspective than the city landscape. The helicopter is -60 degrees relative to the plane of view with a tilt of 30 degrees to give it the thrust it need to moved forwards, and it also has a 15 degree roll because it's starting to turn towards the plane of view. How do you accurately determine where the vanishing points need to be for that helicopter at those precise angles?
I've asked my instructors about how to do this and all they say is, "eyeball it." But, "eyeballing it," doesn't give for precise mechanical measurements for accuracy of the scene. Yes, eyeballing it works, but I'm really looking for a way to make sure that the illustration is as mechanically accurate as possible.
dude I came here hoping for an answer to the same question... have you had any luck since making this comment?
this should help- curvilinear perspective

Hey can you explain what happens when you are looking so far down the horizon line goes outside of the cone of vision?
This simply doesn't or cannot happen. The horizon line represents eye level, it is the eye level of the observer. You can have the horizon line outside of a picture plane but not outside the cone of vision.
you must be talking about three point perspective
th-cam.com/video/gr17_WevIlg/w-d-xo.html
When you use compass to draw a COV, how do you know the extend line of Station point will intersect the circle of COV at Horizon line ?
You find Station point firts then COV or You find COV first then SP ?
You can do either. This is going to sound really confusing because I don't have a diagram, but hopefully it helps.
If you draw a COV first, you draw a vertical line which extends from the central vanishing point down the page. This is done at 3:15
You then decide on an angle for the field of view for the camera.
In most cases, this angle will be 40 degrees for a narrow lens which flattens the image, 60 degrees is the most common used by most artists for two point perspective and 90 degrees is common in many older academic works.
Next, you figure out the angles of the triangle.
Angles in a triangle add up to 180 degrees, and the triangle formed will always be an isosceles triangle (A triangle with two angles which are the same).
If you want a 60 degree cone of vision, the angle at the station point must be 60 degrees. There are 180 degrees in a triangle, so 180 - 60 = 120 degrees.
The other two angles must add up to 120 degrees, and the other two angles are equal to each other. So the two angles measured from the horizon line are also 60 degrees.
Measure 60 degrees down from the horizon line towards the central line, from the points where the COV intersects the horizon line. You see him do this at 4:26 and 4:29
You'll see there is now a triangle drawn on the page. At 4:31 he draws an arc to represent the angle at the station point.
The total angle of at this point is 60 degrees, because it is split in half, it's 30 degrees to the left and 30 degrees to the right.
If you checked either of the angles at the intersection of the horizon line and the COV, you'd see they were 60 degrees.
See how the central line splits the big triangle into two triangles? Each of these triangles add up to 180 degrees. 60 + 30 + 90 (The 90 comes from the right angle from the intersection of the horizon and the vertical line = 180 degrees. If it isn't split into two, the triangle is 60 + 60 + 60 = 180 degrees, which is an equilateral triangle.
If the angle at the station point (Shown at 4:31) were 90 degrees (for a 90 degree cone of vision), then the top angles from the COV would be 45 and 45 because 45 + 45 + 90 = 180. If the cone of vision were 40 degrees, this angle at the station point would be 40 degrees and the other angles would be 70 and 70 because 70 + 70 + 40 = 180.
You'd also find that the station point would be closer to the COV for a 90 degree field of view, and much further away ( probably off the page) for a 40 degree field of view.
To construct all of this without doing the COV first, you could first construct the triangle representing the correct angles for the field of view, and then place a compass on the central vanishing point and extending the compass to the intersection formed by the triangle and the horizon line. You would then draw a circle and you'd get the same result. This approach would be useful if you didn't know how big your drawing needed to be to capture the station point on the page, as you could shrink the size of the circle to fit the page in proportion to the distance of the station point.
KawallaBair fantastic explanation
What did you use to draw that circle ?
Thanks u so much !
PIN MY COM
NICE VIDEO BRO .
MAKE MORE DRAEING PORTRAITS OR SOMETHING LIKE THAT
Im looking for techniques on how to put the vanishing points outside without messing up the whole drawing yk?? Like do yall put tape and add vanishing point on the table💀
Why would you want two different sets of vanishing points in the same image?
every object has its own set of vanishing points. Stack up some books (without lining them up) and see. You can use only one set, but only in very simple drawings where theres only one object or all of the objects are lined up (which looks very boring)
Whats the point of pointing in more vanishing points? Why not use the same on all figures?
Lord Beerus watch the most recent video I did on the cube it should help explain that
