Pencil or pen for perspective learning

both

whatever you like later on, but it's recommended in the beginning exercises that you get comfortable with a pen first

this book is a nightmare!!

stuck on chapter two. dont know what the hell he is talking about

I started out using a Pilot ballpoint that I tried and I liked in a local store. I didn't like using gel pens (Pilot Hi-Tec) because you can't make faint lines as easily.
I use mechanical pencils too, it doesn't really matter as long as you are capable of making faint lines.

What's your problem with Chapter two? I can help you out.

Okay here's a breakdown, hope it helps. Sorry for the dumb terminology but it's for clarity's sake:

The STATION POINT represents where your physical eye is.

Draw a line straight ahead from your eyeballs to the horizon and you get the CENTER OF VISION.

Now imagine a 3D cone radiating from your eyeballs, like an ice cream cone poking you in the eye. That's your CONE OF VISION, and it represents your field of view / your "camera lens".

Generally you wanna keep the width of that cone at about 60° to make things look plausible to a human viewer. When you draw outside of that cone, stuff will start to look weird. If you were a deer or another animal with eyes on the sides of its head, that cone would be much wider and so on.

On the horizon lines there are VANISHING POINTS which are explained in the book.

Those vanishing points connected with your station point will ALWAYS form a 90° angle. You can literally point the corner of a square on the station point and pivot the shape around that point to create new couples of vanishing points that are perfectly usable.

With all of that in mind, the PICTURE PLANE is basically the flattened version of the real world that you eventally put on paper. Try to disregard this first and understand first what the setup of real-life vision and vanishing points, station point etc. mean in your everyday life. After that, the picture plane becomes really obvious.

3-point perspective basically adds a 3rd vanishing point where vertical lines converge. You can realistically choose this point as an arbitrary point that is far high up on the canvas.

What I do (traditionally) is is place a little bit of masking tape way up outside the canvas, where I want the third vanishing point to be.

When using 3-point perspective, choose to stay either above or below the horizon, otherwise you'll have to start curving your vertical lines.

You can disregard curvilinear perspective, you're gonna have to use a computer for that anyway.
