In some cases, we can't directly show it to the audience in kind, and the traditional model can't give the audience real feelings. Simulated holographic imaging can show the whole picture of the content to be displayed to the audience from multiple angles and in all directions with a virtual three-dimensional image. At the same time, simulated holographic imaging can give the audience a strong visual impact and mystery. Three-dimensional still life, animals, plants or people are the most suitable imaging content, which can be accompanied by appropriate changes, but not suitable for complex background. The exhibition mainly shows the monomer itself, which can be extended by explanation or other means, but it is not suitable for content with strong stories. The characteristic of the display item is that it can create a three-dimensional image in a three-dimensional space, so we can express it on a three-dimensional carrier (for example, stamps are flat and single-sided items, and we can stick six stamps on six faces of a regular cube to express it; Another example is the map of the world, which can be directly displayed by the globe.
Through interactive technologies such as VR, the audience can choose to watch different display contents, choose their own perspective, enlarge or reduce the whole picture or details of the display contents, and fully realize the interaction. This cannot be achieved by physical or model display.
