A Review of Virtual Art: From Illusion to Immersion

Representing our perceptions of reality through an aesthetic construct has been, for centuries, the goal of artists. Grau's analysis of early illusory art in the seound chapters, he brings murals as a point of introduction into the reader's perspective,  and one of the main points he makes is that the computer-generated virtual art of the late twentieth and early twenty-first century, as an illusory art, is not revolutionary or new, but fits into a tradition of illusion that dates back as far as 60 BC. When it comes to classical painting, he mentioned some paintings on the walls of the room. Grau thinks how these types of murals constitute the illusion space, because these images are not continuously experienced, it part of "uniformity of space and time". During the Renaissance, Grau noticed the influence of perspective on painting. As a style device in murals, Grau claims that the angle of view is the most effective in eliminating the distance between the observer and the observed person.  In some fine pages Grau goes into considerable detail concerning the construction of panoramas, the controversy surrounding them, and their economic significance.

Grau claims that every instance of hallucination will cause the observer to immerse himself in the space of the image, but his understanding of immersion has been wavering: one thing he claims is that immersion involves improving the emotional sensitivity of the observer.

Hoffman uses the computer desktop icon to make an analogy. For example, the icon is blue, rectangular, and located in the lower right corner of the desktop. This does not mean that the files in the computer are blue, rectangular, or in the lower right corner of the computer. so what we perceive as a computer desktop hides the real world. Reality is more like a 3D desktop, designed to hide the complexity of the real world and guide us through various behaviors. The space and time you perceive are your interface, and the various objects with entities are the icons on the desktop. Evolution gives us an interface that hides facts and guides us to make adaptive behavior. They do not need to reflect the physical world truthfully, but only to meet the basic requirements of living. Because if the real world information experienced by the creature does not help to survive, it will become an additional burden and thus be eliminated in evolution.
