Jaik, sorry it took so long to respond. I've been away for the holidays, as I'm sure a lot of you guys have. The cone does affect the vanishing points and the vanishing points affect the cone. Kinda confusing to describe without a diagram, so I've posted a simple one to help. In 1pt, the station point and our center of vision is directly in line with our vanishing point, as you can see here. This is true for every time you're in 1pt perspective to a scene/object/etc. In 2pt, our vanishing points form a right triangle with the station point at the 90 degree corner. It makes sense if you think of everything as how your vision is orientated to a rotating box. In 1pt, you're seeing the front face and nothing else. Think of standing straight and staring directly at a wall without turning your head at all. Now if you were to look slightly to the right or left, you're effectively "turning" your orientation to the wall, or, in the case of the box, if you were to stand still and it were to rotate instead this puts you into 2pt perspective. 3pt is when you add another dimension to it and look slightly up or down. Knowing this, we can find the accurate placement for our vanishing points if we know where our station point lies. In the diagram, I randomly chose the right vanishing point. I then followed that back to the station point and created a 90 degree right triangle back to my horizon line. This gave me my left vanishing point. This is how you can reverse engineer perspective from a painting or photo as well. If you follow your vanishing points to your horizon and establish your center of vision (which in a photo is always in the center unless it's been cropped) you can use a right triangle to find exactly where your station point lies. From there you can correctly establish scale, measurements, etc. If you really want to delve into it deeper, I suggest checking out newmastersacademy.org. The 80+ hours or so that Erik Olson has posted on perspective is alone worth the $19 a month. Hope it helps. Let me know if I can help further.
As I said, I'm back from christmas holidays, so I'm getting to work again. I've set a goal to have 12 solid portfolio pieces by summer so I can start looking for freelance work seriously.
That being said, here are some studies and sketches to start of the year, as well as the previously mentioned diagram.
