This is very interesting. After trying it out I have a few observations and a question. - The most important point seems to be the center vision 'dot'. - In one point we pan the box around freely and all receding lines go to the central vanishing point. - In two point as we rotate and object the vanishing point begins to drift along the horizon or the vertical line relative to the center vanishing point of a parallel object. If this is true why do so many beginner perspective lessons emphasize the horizon line? I personally feel it is easier for me to understand when I think about how things drift away from that center point as we manipulate objects. The horizon line seems arbitrary when I really start to think about it.

Digitally did some things around my house and next day some thumbnails of some 3d models I found. Anyone else have the problem of not knowing what they want to draw? Feels like finding interesting reference online is harder then It should be and everything around me is kinda boring. https://sketchfab.com/3d-models/tavern-by-duduoliveira-d2dfb0104cfc45de826cbbc4069f1774

Definitely takes alot of energy to do this. I find it Really interesting how it boils down to form transformations on a box in perspective. As a beginner people always tell you to draw things in boxes, but knowing how to use the box you created is actually very hard.

I am really starting to see the value of this the more I do it. It Really let's you figure out proportions with less distractions. Also I am seeing why boxes are so handy. If you keep the rectangle around your othos you can project them into a box with the same proportions! The box is your guide and everything that lines up in the orthos projects to the same vanishing points. It's really neat and actually feels like I am building a process to draw anything.

This took a while for me. One thing I need to work on is keeping the page clean. I smear the pencil so easily. Both with my hand and ruler.

My family's names to start. Here is bad art joke I thought of: I love studying perspective because it's the only time in my life I can improve linearly.

Not very rocky but trying to practice extrusions.

This was fun to do.

Squid like character from imagination. Trying to use the techniques shown here.
