The latest 3D technology available and upcoming in the market all explained and analysed. The application of such technology for events purposes, and how companies have used it to upscale their events.
Features of 3D Projection
3D Projection mapping also referred to as video mapping and spatial augmented reality, is a projection technology used to turn objects, often irregularly shaped, into a display surface for video projection.
3D projection is capable of creating mind-bending effects through warping content with controlled software, as images take on physical form. We can add inanimate objects onto your stage and create illusions surrounding your guests through 3D mapping.
3D projection requires technical and AV equipment as well as architectural integrity of the system.
It is the perfect way to take your event to the next level and create something truly eye-catching and intrigue your target audience.
History of 3D
One of the first public displays of projections onto 3D objects was debuted in 1969, when Disneyland opened their Haunted Mansion ride, which featured singing busts. Head shots of the singers were filmed on 16mm film and then projected onto busts of their faces to make them appear animated.
The next record of projection mapping is from 1980, when installation artist Michael Naimark 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 as a means of technological advancement. 3D has grown widely popular in many events such as movies where they are now created with 3D options.
Types of 3D Projection
Active 3D uses battery-operated shutter glasses that do as their name describes: they rapidly shutter open and closed. This, in theory, means the information meant for your left eye is blocked from your right eye by a closed (opaque) shutter. All that’s required of the TV is the capability to refresh fast enough so each eye gets at least 60 frames per second. They’ve been able to do this for a while.
Active 3D can be found on plasma, LCD, LED LCD, and all front and rear projectors for the home.
Passive 3D uses inexpensive polarized glasses, like what you get at most movie theaters. The TV has a special filter that polarizes each line of pixels. This filter (a Film Patterned Retarder is one type) makes the odd lines on the screen only visible to the left eye, and the even lines only visible to the right. Without the glasses, the TV looks normal.
Passive 3D is available on some LCD and LED LCDs
With active, each eye gets the full 1080p resolution of the source. On the other hand, the glasses make the image look dimmer, as they block some light. With LCDs this isn’t really a problem, but with plasma and front projectors, it’s more noticeable. While some of the glasses are lightweight, most aren’t.
With passive, each eye is only seeing 1,920 x 540 pixels due to the polarized lenses blocking half the lines. If your screen is big, or you’re sitting close (how close depends on your eyes and the size of the screen), you’re going to see what look like interlace lines, as in black lines in between the active image (see images above). Even if those aren’t visible, the jagged diagonal lines they cause might be. On the other hand, more light makes it to your eyes, so the image is typically brighter with passive. The glasses are also really cheap and lightweight.
Technology in Market
Liquid Crystal Display (LCD) technology passes light through a liquid crystal material. In comparison, Digital Light Processing (DLP®) technology is reflective. Light bounces off of Digital Micro mirror Devices (DMDs) – tiny mirrors that each reflects a single pixel in the resolution of the projected image.
The advantage of DLP technology is:
better colour control, since each individual pixel is controlled.
A smoother, cleaner, seamless digital picture since the space between the DMDs is less than the space between the LCD crystal cells.
DLP projectors also tend to be brighter than LCD projectors, which lose some light as it passes through the liquid crystal panels. As a result, DLP projectors can produce higher brightness from smaller units and use less power to achieve the same levels of brightness compared to LCD projectors.
Xenon lamp technology
Xenon lamps produce light with a broad colour spectrum that matches what the human eye can see. The result is a natural light that renders colour well. Because the colour temperature of the lamp can be controlled over a broader range, xenon lamps are well suited for applications such as high-performance data visualization where this control is critical.
Xenon illumination’s brightness can also be controlled. Adjusting the levels of power to the lamps creates brighter or dimmer light, which allows for brightness-level matching across multiple displays. 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 technology and integrate it with their respective technologies/innovation to generate advanced 3D experiences catered to their clients needs. Many of these technology are highly secretive and patented due to its niche specialization.
