One Point Perspective

This post is about one point perspective is when you look at some thing it's became three dimensional. For example, When you look at a head of the play come straight to you see at one point and 1 perspective.
When it came to paper you will have a sheet of paper and the picture look 3D.
The history is that most of the drawing in the past was mostly about religious but the Egyptian use thing called Vertical Perspective it's kind of like one point perspective because it use that to build pyramids.
In the One Point Perspective picture has three common things that you can find on One Point Perspective picture:
Vertical
Horizontal
orthogonals
Vanishing Point
Like this picture









In this picture you can see the road I can see three things:
Vanishing Point is where the road go to meet up on horizon and horizon is where the land meet up with the sky.
Parallel line that is the left and right line.
Vertical line the up and down line.
