Glasses-free 3D is not limited to outdoor large screens
In recent years, ocean waves, spaceships, light rails, pandas, lions, and stars have appeared… Naked-eye 3D has blossomed everywhere, and it is frequently searched. And this “breaking circle” technology has gradually matured, and is favored and sought after by many application fields (electronic products, advertising, media, demonstration teaching, exhibitions, etc.).
How the naked eye perceives 3D
Humans have an innate ability to perceive and understand the 3D environment. This is because the two eyes of a person are in different positions, and the distance between the pupils is about six or seven centimeters. When a person observes an object, the images observed by the two eyes is different, the deviation between the two images we call parallax. It is this kind of parallax that enables people to distinguish the distance of objects and obtain a sense of three-dimensionality.
According to different parallax values, parallax can be divided into positive parallax, negative parallax and zero parallax. When the audience is watching, positive parallax makes people feel that the object goes deep into the screen; negative parallax makes people feel that the object is suspended outside the screen; zero parallax is the boundary between positive and negative parallax, the object is just projected on the screen, that is, we The so-called zero plane.
Using this principle, motion graphics designers can display two left and right images with parallax through the monitor and send them to the left and right eyes of the audience respectively, so that the audience can experience the realistic and shocking 3D at a specific angle without using other equipment. Visual effects.
Application advantages of glasses-free 3D
1. You can watch 3D stereoscopic visual effects without any auxiliary equipment. Its realistic three-dimensional sense, immersive experience and cool surprise can attract more eyeballs, gather more popularity, and help Enhancement of brand advertising value.
2. The unrivaled color reproduction and exquisite detail presentation of naked-eye 3D video provide a sustainable and intensive path for the construction of brand communication.
3. Creative DIY, create different 3D creative animations according to unique brand cultural characteristics or application scenarios, create unique visual art works, and bring novel and unique visual experience to the audience.
4. There is no requirement for ambient light, and it can effectively eliminate moiré, with high definition and large visual depth, so that the audience can have a shocking visual experience, and at the same time, it can ensure that tourists who come to check in as souvenirs can shoot in higher definition.
Glasses-free 3D application field
Advertising media: Based on the “exhausted talent” of print advertising in terms of creativity, naked-eye 3D advertising is widely used in airports, subways, high-speed rails, hotels, elevator entrances, corporate stores, shopping malls and other application scenarios in brand marketing and product display.
Exhibition display: The novel and vivid naked-eye 3D is widely used in industry exhibitions, science and technology museums, museums, Real estate real estate and other scenes.
Entertainment activities: With the enrichment of the entertainment industry, consumers have increasingly demanding environments and services. Naked-eye 3D technology helps places realize The interactive experience introduces products and services and fully immerses customers in a realistic three-dimensional world.
Cultural tourism activities: The combination of traditional tour display methods in tourist attractions and creative projection shows has driven the development of cultural tourism industry and boosted the growth of night tour economy. Applications include outdoor projection, multimedia drama, themed water show, cliff projection, live performances, characteristic blocks, etc.
Popular science education: Some advanced scientific knowledge needs to be presented in an intuitive and visual way, ranging from the science popularization of the universe to the exploration of cells. Glasses-free 3D can play an important role.
