One point perspective
One point perspective first came into use around the time period of the 1400 and artists such as Filippo Brunelleschi excelled the theory in to use.
On point perspective is a type of linear perspective exactly the same as parallel perspective it combines a mathematical systems along with a vanishing point in order to represent three-dimensional objects on a two dimensional surface. This is achieved by intersecting the lines that are draw either horizontally or vertically. From the vanishing point the lines radiate outwards giving the illusion the viewer is looking into the picture and can sense the depth of distance. Therefore when typically drawing railways,roads,buildings or halls using one point perspective it gives the illusion that’s the object is directly facing the viewer, and gives a sense of depth.
Two point Perspective uses exactly the same method as One point Perspective does however, T-PP has two vanishing points usually 90 degrees apart on the horizon and all lines radiate from those points.
