Event Tech Case Studies, Applications, Technologies
The latest 3D-Projection technology available and upcoming in the market, their features and applications for events. We also analyse how companies have used such technology to upscale their events. So how exactly does 3D-Projection work?
Relatively new and upcoming digital company, Qwartz, created a really interesting and insightful video of 3D Projection mapping.
Features of 3D-Projection
3D-Projection mapping, also known as video mapping or spatial augmented reality, is a projection technology that turns objects, often regularly shaped, into a display surface for video projection.
3D-Projection creates mind-bending effects through warping content using extensive software, allowing images to take on a physical form. Through the use of 3D-Projection mapping, the inanimate objects are turned into real-life looking illusions to captivate audiences.
3D-Projection requires highly technical and advanced Audio/Visual (AV) technology and equipment, as well as architectural integrity of the system. It is the perfect way to take events to the next level and create something truly eye-catching and intrigue target audiences.
History of 3D-Projection
3D-Projection technology is relatively new in its discovery. In 1969, Walt Disney’s Disneyland opened the first ever 3D Haunted Mansion ride. It featured scary images being projected using 3D-Projection technology to appear animated. This revolutionary technology and it’s application built the foundations for many theme parks and attractions to come.
3D-Projection did not become an instant hit, and it took close to a decade later for the application of projection mapping to resurface through an artist named Michael Naimark. He filmed people interacting with objects in a living room and then projected it in the room, creating illusions as if the people interacting with the objects were really there.
By 2001, more artists began using projection mapping in artwork, and groups such as Microsoft began experimenting with it to further technological advancement. 3D-Projection has grown significantly popular in many events such as movies where they are now created with 3D options.
Types of 3D-Projection
Active 3D comprises of battery-operated shutter glasses that rapidly shutter open and close. This creates a disparity between the images that is depicted from your left and right eye. For the TV’s technology perspective, it is required to be able to refresh quickly to ensure each eye gets at least 60 frames per second. This has been widely available throughout the market for quite some time now.
Active 3D can be found on plasma, LCD, LED LCD, and all front and rear projectors for the home.
Passive 3D utilizes polarized glasses. TV is made with a special filter that polarizes each line of pixels. This special filter makes the odd lines on the screen only visible to the left eye, and the even lines only visible to the right. Therefore, the TV looks completely normal without the glasses, but appear animated when seen through the glasses. Passive 3D is available on some LCD and LED LCDs.
Active vs Passive 3D-Projection
Each eye gets full 1080p resolution from the source when using Active 3D. The 3D glasses make the image look dimmer since they block of a certain amount of light. With LCDs, this problem is minimized due to their light displaying properties (Explained Below). But for plasma and front projectors, they become avidly more noticeable.
With passive 3D glasses, each eye is only provided up to 1920 x 540 due to the polarized lenses blocking half of the lines. Depending on how close you are or how big your screen is, certain jagged diagonal lines may be visible. However, more light makes it to your eye as compared to active and thus, image is generally brighter. The glasses used in passive are typically more lightweight and also cheaper as compared to active.
A great short video on the difference between active and passive 3D glasses.
Liquid Crystal Display (LCD)
LCD technology is commonly used to incorporate 3D-Projection. It that allows light to pass through a liquid crystal material. They do not emit light directly, but instead use a backlight or a reflector to produce images in colour or monochrome.
Digital Light Processing (DLP)
DLP technology is another commonly used together with 3D-Projection. Unlike LCD, it is reflective. It allows light to bounce of digital micro mirror devices (DMD) that reflect a single pixel in the resolution of the projected images. DLP technology allows better colour control, since each individual pixel is controlled. It also facilitates a smoother, cleaner, seamless digital picture since the space between the DMDs is less than the space between the LCD crystal cells.
DLP projectors are usually brighter than LCD since some light is lost while passing through the liquid crystal panels. Thus, DLP projectors use smaller units and can generate greater brightness than LCD projectors while also using less power to achieve the same level of brightness compared to LCD projectors.
Xenon lamp technology
Xenon lamps technology is the newest of the 3 and is the latest method that is used to incorporate 3D-Projection. It produces light with a broad spectrum that is catered to what the human eye can perceive. By adjusting the level of powers to the lamp, light can be brighter or dimmer. Xenon lamps allow better control over the spectrum of colours in general and thus, are highly advantageous for 3D-Projection where control is essential. This brightness control also results in greater control over power consumption and lamp life and that influences your operational costs. Xenon lamps produce short wavelength, ultraviolet radiation and intense emissions in the near infrared, which are used in some night vision systems.
Many companies use these proven-reliable technologies and integrate it with their respective technologies/innovation to generate advanced 3D-Projection experiences catered to their client’s needs. Many of these technologies are highly secretive and patented due to its niche specialization.
