Constructive construction of geometric bodies in sheet space

Starting to study the drawing at this stage, it is necessary to clearly understand your goal and objectives. The goal is to draw a still life of geometric bodies, and one of the main tasks is to draw the shape of an object in space, and transfer its volume. Any object is in space, it can be circumvented and viewed from different angles.

Space is what surrounds us or an object, that is, the environment. The main constructive property of our environment is its three-dimensionality. The space has a height, width and depth. Any object, being in space, obeys the laws of this space, that is, it is three-dimensional. For a model of space, you can take such a geometric figure as a cube, with all its sides and faces. The cube has an upper surface, a lower, anterior, a posterior and two lateral ones. Space also has top and bottom, four cardinal points.

So, we have determined that the space in which the still life is located is three-dimensional. Still life objects have a height, width, depth. To convey the three-dimensionality of still life objects in our drawing, we lack one dimension of space, that is, depth. The space of the sheet on which we want to draw a still life is two-dimensional. It has a height, a width, but has no depth. To create the depth (illusion) of the sheet space (the volume of still life objects), it is necessary to use the perspective method. What it is?

Perspective (French perspective) - “penetrate with gaze”, “see through”. Creating a three-dimensional image on a plane is carried out in various ways. Any image on a plane can be considered as a projection of a real or imaginary object on a given plane. One type of projection is perspective. It allows you to create the most convincing image of three-dimensional space on a two-dimensional plane.

By transmitting space and still life objects located in space, on paper, we use the direct perspective method. This method has two features: a) all parallel lines extending into the depth of the plane converge at one point, which is on the horizon, and all objects (as they move deeper) decrease in size; b) the horizon line, regardless of whether you are sitting or standing, is always at the level of your eyes.
