Mechanics of Perspective Drawing

There’s a lot of factors to consider when working on the perspective drawing. Perspective drawing is done in accordance with certain elements and procedures.

Cone of vision, the cone of vision is normally 180 degrees in range. It is the portion that we also called as the field of vision. In working with the preparation of the perspective, the field of vision is reduced into a cone of vision in about 60 degrees; it is done to avoid any distraction in the drawing.

Station point or viewing point, the station or viewing point is the point from which the object is viewed. This is the apex portion of the cone of vision. It is where the observer views the object.

Picture Plane, the picture plane is vertical and in the right angle. It has an imaginary line called as the line of vision; that projects from a station point. Th picture plane is an imaginary plane in which the object is projected.

Ground Line, the ground line represents he ground through a horizontal line in relation to the eye level of the viewer.

Horizon Line or eye level, the horizon line or eye level represents the height of the eye through a horizontal line. It is normally 5 feet in scale measurement in relation to the ground line.

Height line, the height line is a vertical line. This line is used to measure the height of the object in perspective.

Vanishing Points, the vanishing point is the point in the drawing which the lines of the object converge or meet.
