Constructing Perspective

[Anonymous No.7098617]

How do you 'construct' a scene with a large amount of perspective from the beginning?

I've been through 3 perspective books including Perspective Made Easy
Yet none of them show how to actually construct a scene that largely deviates from the horizon line from the beginning. In pic related I tried to create a simple 3 point looking down onto a city scape, however to even partially get the effect the VPs, Horizon ETC all had to be super far away with a massive canvas. I increased the size on the middle one obviously so you could see what I wanted to draw.

Is there a better way to do this, or is this just the normal process when you're going for a further angle away from the horizon?

Thanks anon I've just read through the blog along with your image.

To sum it up:

>create a miniature version of what I did, perhaps with only a few buildings to establish the perspective
>take the drawing, make it the desired size (EG big canvas), and put a few equal distance markings around the work area that points to the relevant VP
>continue working in a non autistic fashion by using these markings instead of making literally everything reach the VP that is a massive distance away


Is this correct?

I know this isn’t answering your question, but the near angle on the tops of your buildings is acute (less than 90 degrees), when it should be obtuse. Think about it: If you were directly above the scene those tops would be perfect rectangles (i.e. have 90-degree angles at each corner). As you lower yourself, two of the corners (the near and far corners relative to you) would appear more open/blunt while the other the other two would appear sharper/more pointy. Try this with a table-top or box and you’ll see. If the near corner in your drawing is acute, you know the VPs are too closely spaced and you are getting distortion.

Also, since you are viewing the scene from above looking down, there should be a third VP, to which the height lines of the buildings converge. You have those lines parallel, which makes this scene look kind of look an orthographic projection as you might see in a video game (like one of the Sim City games).

Thank you anon even if its not answering the question what you're saying adds a lot to my learning. I just tried with a real life box doing the descent in comparison to it and I can see it now. Is the solution to keeping a more believable perspective pushing my VPs (like in my OP pic) even further apart?


For the second part, where exactly should the third VP at the bottom be placed? When I drew the OP I was conscious of it, but 'imagined' it so far down that there is very little converging of lines at that point, how close exactly should it be to the canvas for a scene like this?

what you want to create is top-down view. For that you need 3P perspective system (or 5P aka fisheye). 3P is omitted in some basic books. I recc
Marcos Mateu-Mestre: Framed Perspective volume 1 and 2. Pic very much related: notice how the buildings have 3 vanishing points: 2 on the horizon, 1 bellow the ground called zenith

https://docs.krita.org/en/user_manual/painting_with_assistants.html
i recc using the vanishing point helper

Thanks Pawell, haven't seen you post outside of beg. I may go through that book next then as each of these only add to my knowledge. I just finished Dong Ho Kim - Space Drawing Perspective-Superani and gained the most out of it from any book I've been through but setting up a convincing looking far away scene is still a struggle

I am occupied at the moment but will answer your questions later.

[Anonymous No.7098719]

in CSP you can place vanishing points outside the canvas
and also use the perspective ruler from a 3D object, so you can visualize exactly what you want

[Anonymous No.7098733]

>>7098719
Im unaware of both of these features. Ive only moved to csp recently, where do you get perspective ruler from a 3d object?

wow thank you so much this will help a ton, I came from using Krita for a year and theres so many things I've completely unaware of that CSP has.

Perhaps you can just use the CSP features mentioned by another anon. I am a paper-and-pencil guy myself. In case it might still be helpful, I've attached a mockup showing what I think are some useful pointers.

Draw the horizon line, then mark a point somewhere off below the picture (this needn't be centered, but it is in my example). From this point extend two perpendicular lines (i.e. forming a right angle at the point below the picture) toward the horizon. Where these lines touch the horizon is where your VP 1 and 2 are located.

We have essentially just drawn a right triangle, with the right angled vertex below the picture, and the hypotenuse as the horizon line.

Because we located our VP 1 and 2 from a right angle outside the picture, the square planes (building tops) drawn inside the picture will not be distorted. Note, however, that if you go far outside the lines of the triangle (such as near the corners of the picture shown) you could still end up with distortion; position your points accordingly.

VP 3 can be placed somewhere down below; putting it closer to the picture produces a more violent perspective. Use your judgement.

You would probably want your horizon line farther away from the picture than I have it, but not nearly as far as it is in your drawing.

There are mechanical methods for accurately constructing objects in perspective without the need for VPs, but these require plan and elevation drawings and are not suited to freehand sketching. For most artists, what's important is to be able to work freely and quickly while avoiding obvious errors. If it looks right, it's right.

Thanks anon this is very in depth, I was unaware of most of what you typed especially the 90 deg part. ill practice some more and probably post here if the thread is still alive

this, how do you place VPs if you want to make a scene that is looking like you're looking off the edge of a skyscraper, not at the angle op is showing which is like 45deg

[Anonymous No.7101465]

>>7101374
Easiest way is to treat it like a 1-point perspective. The tops of the buildings are squares/rectangles and the sides of the buildings recede towards a vanishing point somewhere near the middle of the picture. You are looking straight down instead of straight ahead towards the horizon, so you'll see the tops of roads, cars, etc.

take a picture that has that angle and reverse engineer the vps
then remove the image and make a new scene

Thank you clip studio paint, very cool

The answer seems to be developing a fetish for buildings.

I can do that.
