Drawing from nature, the surrounding objects, mentally comparing their sizes on a sheet defining certain relationships, we are always guided by the laws of perspective and thereby achieve a true and faithful depiction of reality. Solid knowledge of the laws of perspective is required for each artist and architect. The practical significance of the theory of perspective in art and architecture is well known.
Errors in the figure, the lack of similarity between the image and the original in many cases are due to a breach of the rules of linear perspective. In this case violated not only the resemblance, but also the veracity and credibility of the picture as a whole.
Perspective - a way to images of objects and space on the plane in accordance with the apparent reductions in the size and shape changes of the surrounding bodies, which the viewer observes in nature. This definition, on the one hand, it provides an indication of the geometric basis of the discipline as a way to images of objects on the plane. On the other hand, it emphasizes the link with the laws of perspective and perception, of whom the prospect of coming to their scientific foundations.
As a means of representation, and geometric perspective and drawing from nature is a common goal. With their help, the person on the plane represents the surrounding objects as they appear in space. However, the pathways leading to this goal, for drawing and perspective are different.
Building future images should always be strict geometric systems. In the drawing, on the contrary, the artist is guided by the subjective assessments and judgments, referring to the geometric patterns as a means to support the check.
The strict logic of geometric constructions has always attracted artists and architects who have studied vocational theory of linear perspective. However, the techniques of perspective constructions were developed initially as abstract geometric no scheme, and as a result of a theoretical generalization of the scientific evidence on visual perception. It is so on the theory of perspective, its creators, artists and architects of the Renaissance who regarded this discipline as the science of vision and visual rays. |
