Re: Basics 101: Class 2 - Foundation of Perspective

Arnoud-- I have a very basic question. While I know VPs exist off the paper, should the horizon line always be on the paper?

Thank you!

Kate - In theory there is no problem in putting the HL off the paper. Because every painting is a crop of the field of view. But it is not logical. The HL - aka Eye Level - is where you put the eye level of the observer. Not the observer OF the painting, but the observer IN the painting. It sounds bizarre but I mean e.g. in a landscape, where you suggest the eye level of a person strolling through the landscape.

But yes, it can be done for particular effects, and it is a regular trick in comics.

But while thinking about it, I'm still a bit confused.

If I understand correctly, the HL is a (horizontal) plane on the eye level of the viewer. Everything below (and above) converges to this plane. But, this would mean that train tracks do actually not converge to the real horizon (the 'edge of the world' on a beach), but to a plane slightly above. Is that correct?

It is not a plane but a line (Horizon Line), but yes, it is the same as the eye level.

Not quite, only horizontal lines converge to the horizon line - there is a reason for this linguistic correspondence .
Other parallel lines, for instance of a roof, converge as well, but to a VP above or below the HL. But how to find them is advanced perspective, this class is only for horizontal lines.

Definitely not so, the "edge of the world" IS the eye level.



If you don't trust geometry, try it out: let a friend take place between you and the visual "real" horizon. If you're of about the same height and the ground is flat, your head, his/her head and the "edge of the world" will be in one line.

I see, thanks for explaining!

Re: Basics 101: Class 2 - Foundation of Perspective

Hello again. I drew a herd of cubes (and cube-like shapes). It was more fun than I thought, perspective is a thing that has always scared me away from drawing but it might not be so terrifying after all...



And now on to the boxes!

Re: Basics 101: Class 2 - Foundation of Perspective

Hi
I hope it's ok to do this.

I thought I'd post these to make sure I'm on the right track before doing the rest of the exercises.

1 point


2 point


Having fun with 3 point. I could get obsessed with this


Cheers

Re: Basics 101: Class 2 - Foundation of Perspective

No problem so far, Simon .
But take care: when constructing perspective, instead of drawing from life or reference and using VL's to check the perspective, there is a strong tendency to put the VP's much too close together. Like in your rightmost examples of 2PP and 3PP.

Keep up the good work

Re: Basics 101: Class 2 - Foundation of Perspective

I hope these pictures are clear enough. Unfortunately I'm working in crappy lighting conditions and my camera is subpar, sorry for that.

This is my tea box. I put it straight in front of me. The squiggly lines are a pattern I had no patience with The letters in the front were a challenge! I liked that. But I lost my patience at the top of the box.




For the crate below I used a triangle measure thing (geotriangle?) to calculate the angle of the front and the side and I drew light help lines, after which I filled in the details. The crate itself is a bit crooked and upside down, because I use it as a side table

I sketched standing and looking down on it, added the helplines and went back between standing and sitting for the details. I enjoyed this, I love bare wood. I also love drawing trees

You think too much .
Using technical drawing tools tunnels you into technical drawing principles. The correct reasoning for a beginner in perspective is explained in the first post with the picture of the railway.
The first rule is "further away looks smaller". Really, that should not come as a surprise .
Now what did your technical measuring come up with:



This is the way of the engineer. It is not wrong, but it is not perspective, it is (a kind of) isometric projection.
The way to measure is like you see in almost all caricatures of a painter: looking over the top of his brush handle. But in this case with the handle horizontal. Observe how the back edge is smaller than the front edge.
Take care next exercise

Re: Basics 101: Class 2 - Foundation of Perspective

Hi everyone! Here are 2 steps of second class. I' ve noticed mistakes and pointed them. Well, the task will be done once more, but I'd like to hear your point of view on this stage. And of course I will do boxes. BTW. Should I attach the photo of the box from the point I will draw it?

Re: Basics 101: Class 2 - Foundation of Perspective

Good job so far, Anna
Except of course that design that no carpenter could possibly construct .

One ("housekeeping") remark: try to aim your camera in a right angle to the drawing. Observe the distortion. In fact this is a nice illustration of what we study in this class: "further away looks smaller".



Keep up the good work
