A geometric figure is the visual and functional representation of a non-empty and closed set of points in a geometric plane. Figures that delimit flat surfaces through a set of lines (sides) that join their points in a specific way. Depending on the order and number of these lines we will talk about one figure or another.
Geometric figures are the work of geometry, a branch of mathematics that studies representational planes and the relationships between the shapes we can imagine in them. These are, therefore, abstract objects, according to which our perspective and our way of spatially understanding the universe around us are determined.
It is used in the composition as a counterpoint to architectural balance, due to its character of spatial stability.
The Rectangle :
This operates as a double frame, that is, it reinforces with emphasis the image whose frame is rectangular.
It is an active form, the vertical direction ascends in the form of a pyramid and gives it movement, however when some of its sides are parallel to the lines of the format, it gives the impression of balance or calm.
It symbolizes the infinite, conjugates the beginning and the end, merges the beginning and the end at the same point, the perspective form of the circle is the cylinder, however, it is possible to distinguish the semicircle in it over the squares.
In addition to the geometric forms, there are infinities of forms that make it impossible to group them in a certain segment, these are mostly explicit in nature and are properly called Free Forms, the profusion generated by these are not binding of the geometric forms although these they are not determinants in the scenes, it can be deduced that just as there are free forms in nature, also the geometric ones.
As we already know The Depth in the two-dimensional plane is only an optical illusion creating the sensation of three-dimensionality. On the plane, we should only remember a series of factors that reinforce our stereoscopic vision that serves to interpret the flat monocular vision as three-dimensional.
The visual factors involved are:
- That parallel lines appear to converge in the distance.
- That the shadows give volume effects.
- That the light gives the feeling of closeness.
- That nearby objects are in the foreground.
- That when the objects are close, the textures are detailed.
- That when you are next to an object, you only see part of it, since the rest is out of the format.
- That when objects become foggy or pale they look far away.
- Let the background blur.
- That the position of the light influences the appearance of the volumes and the perspective.
- That warm colors approach and cold ones move away.
