Vanishing Point:Where all the lines converge Horizon lines:The eye level of the viewer
One-Point Perspective: 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. Two-Point Perspective:linearperspective in which parallel lines along the width and depth of an object are represented as meeting at two separate points on the horizon that are 90 degrees apart as measured from the common intersection of the lines of projection.
