How to Make linear perspective easy ?

Linear perspective is one of the most useful tools in your bag of drawing tricks, but many people avoid it because they think it's too much like math. Linear perspective defined Renaissance art and much of realistic Western art up until the last century because it gave artists the opportunity to create infinite depth, like a window onto another world, rather than be limited to flat space. Linear perspective is built on the premise that all things appear to diminish in size as they recede into the distance. You need to understand only the following three concepts to have a working understanding of how to use linear perspective:

Eye level line: The eye level line (also known as the horizon line) represents the level of your eyes when you look straight ahead. Even if you look up or down, your eye level line is determined by looking straight ahead. If you were Superman and used your laser vision to burn a level line around the room at your eye height, you'd have a perfect horizontal eye level line. Every composition has only one eye level line, and it's always perfectly horizontal. In this context, the horizon line isn't the place where the sky and the earth meet; it's just another term for eye level line.

Vanishing points: You've probably seen railroad tracks that converge at a single point in the distance. This point is the vanishing point. Vertical objects, such as walls and rows of windows, trees, and fence posts, also appear to diminish in size as they appear farther away, and the lines that mark their tops and bottoms eventually converge at a point just like the lines of the railroad tracks do. Almost all vanishing points are situated on the eye level line. It doesn't matter whether you draw objects that are sitting on the floor or hanging from the ceiling; they all utilize vanishing points situated on that one eye level line.

Convergence lines: The convergence lines for an object are the guidelines that run through and from the object to the vanishing points. The lines that mark the tops and bottoms of walls, for example, are convergence lines that continue past the end of the wall to the vanishing point for the wall. They're invaluable for keeping windows, rooflines, doorways, and many other architectural details in line.

The funny thing about linear perspective is that it assumes that you're standing in one spot with one eye shut. Hold up your hand and look at it with one eye. Now close that eye and open the other. See how the position of your hand appeared to change? Linear perspective is great for capturing a single point of view and moment in time, but it can be confusing because the view changes if you move.

Whether you're drawing an intimate still life or a building, most of the subjects you draw rely on two methods of using linear perspective: one-point and two-point. Deciding which to use for an object is easy:

If the back wall of a room or the flat plane of a box or building is facing you, use one-point perspective.If you're looking at the edge of a box or the corner of a room, use twopoint perspective.
