| With the integration of art and science and technology,we can see that technology provides infinite possibilities for the shape of image display.The image construction of virtual imaging technology,the construction of immersive aesthetic space and the interactive design of somatosensory interaction make the viewer in it,often produce cognitive illusion,that is,the virtual visual world.The boundaries are so real that they can be touched and felt considerably.At this time,the viewer will recognize this aesthetic state as "real",a kind of virtual reality.Here,there is often a question: what is the "truth" in the cognitive structure of the viewer,and what is the logical connection between art and "truth".If we look back to the history of art,we can see that in surrealist paintings in the 20 th century,the meaning setting of "reality" lies in the construction of the subjective and imaginative world relative to the objective real world.The artist makes the picture clear through "fast writing","object" and the variability of space on the basis of reality.It suggests the reality of the imaginary world of objective reality,but in the most universal perception of the viewer,the concept of truth tends to point to an "objectivity",i.e.the intuitive perception of the creation of the picture space,the shaping of the image of the picture and the characteristics of the object have some relevance,which leads the viewer to follow.In the space cognition of painting,it is necessary to integrate the cognition of objective features and concepts.But at this time,we need to pay attention to the fact that the viewer and painting belong to two domains of meaning.The viewer is involved in painting with his cognitive framework,and the source of the domain of painting ontology lies in the pictorial construction of his creative subject’s cognition.Therefore,this article will take this as a starting point,return to the artist as the main body,take the artist’s painting "ontology" as the thinking point,to think about the artist’s "real" meaning in the painting field,and pay attention to the artist’s own creative system and structure understanding.In order to make the problem concrete,this paper will take the artist Giacometti as a case study,mainly focusing on the process of change of his artistic concept,formal language,time and space,and the way of case study will make the problem-oriented more concrete.The multi-dimensional setting of "truth" in this paper mainly indicates the constant change and revision of the mode of ideas,and the understanding of "truth" by the creator in different situations and cognitive structures is a complex model,and the visual cognition of this complexity lies in the different pictures of the artistic creator.The image structure of time periods,as Giacometti’s visual form,is a continuous implicating of internal and external reality.On the basis of basic theoretical research,we will return to self-creation.In my thinking,the multidimensionality of "truth" lies in the presentation of the essence after a statute,which changes from the single feature in the earlier period to the multidimensional space feature in the later period.In this process,the "truth" has always been the essence.The core of self reflection. |
