I have a really hard time with perspective. I just think my depth perception is really bad. So here’s a quick little snippet about one point perspective.
One point perspective (or single point perspective) is a “mathematical system for representing three dimensional objects and space on a two dimensional surface by means of intersecting lines that are drawn vertically and horizontally and that radiate from one point on a horizon line” (source). In other words, there is a horizon line with a single point at which all things converge and “vanish”. A few examples:
Notice that the vanishing point does not necessarily have to be central.
