WELCOME! TO OUR PERSPECTIVE 101... SAMPLE LESSON
A human being standing in the middle of a 360• circle has the ability to see 180• (half) of that circle in front of them. Our eyes see only a portion of this half circle clearly in front of us, which amounts to a 60• angle. It is almost as if we gaze through a megaphone shape.
This clear vision area is called the ConeofV (Cone of Vision). Objects within
this area are "safe" for drawing, while objects located outside
of it appear distorted and diffused similar to what we see when we look through
a wide-angle camera lens. There are scientific reasons for the existence of
the distortions we make on our flat surface drawings because we have "curves",
telling "flats", what to do.
We see things through 2 curved camera lenses that talk to each other in our
brain about what they see. These curved lenses are called eyes. They look
at what they see in-front of them and then send the information back to our
brain. It is our brains job "to compare between what the left side saw
and right side saw". It compares and then tries to guess at how far away
the object is, by drawing triangles to measure distance with. Triangulation
and a little more comparison and, "Presto, there it is! Our own original
interpretation of the view, faster than any computer processor ever thought
of being.
Separate visual images are collected with our eyes and then sent back to our
brain. The left eye sees the view at a different angle than the right eye.
Our mind receives the information and produces it’s best estimation
of a single 3D interpretation from the 2 separate images, intermingling them
and triangulating distances to produce it’s best guess.
Our eyes are little busy bodies because they naturally rove around constantly collecting pictures and sending them to the brain, who simply adds that view to the adjoining view automatically. Two automatic image scanners working all the time. Before we know it, we have a whole collection of snapshots pasted together showing us the view all around us. Amazing! What is important to remember from all of this is, that when we draw our perspective drawings it is from only 1 second of this process. Only a view "frozen-in-time". For our drawings to be right we only work from one snapshot of 1 view from exactly here with no movement allowed. We don’t look at the object and turn our head to see what is on the right side of it and add to our previous view.
