Shutter glasses either have two rotating discs, or two LCDs, one directly in front of each eye. The LCD system blocks one eye’s view onto the screen. When an image for the left eye is drawn on the monitor, the LCD of the right eye will block the right eye’s view and the other way round. If this is repeated fast enough (faster than can be perceived), and if the synchronization can be kept, then this will make you think you’re seeing true 3D.

Benefits: ultra clear 3D imaging and eliminate «ghosting» which is a problem with other 3D display technologies such as Anaglyph, stereoscopic image can be projected on any surface.

Disadvantages: special demands to 3D equipment, occupy a lot of place, stereoscopic technology reduces an image resolution. Flicker can be noticeable except at very high refresh rates, as each eye is effectively receiving only half of the monitor’s actual refresh rate. Because the LCD shutter glasses are shutting out light half of the time, and are slightly dark even when letting light through, less light reaches the viewers eyes from the display. This gives an effect similar to watching TV with sunglasses on, i.e. a much darker picture.

Price: high (about 100 Euro – per glasses pair)

Infitec™ delivers superior stereo separation without ghosting, with full freedom of motion, independent of head tilt. Two optical Infitec™ filters split the color spectrum in 2 parts: one for the left and one for the right eye information.

Trans-Force attraction uses the latest stereo technology – Infitec™ based on completely new technique of Wavelength Multiplexing. It delivers superior stereo separation without ghosting, very homogeneous and serene images (like in high quality mono projection) with full freedom of motion, independent of head tilt. Infitec™ stereo display technology makes it possible for the user to produce large-sized pictures on every white projection surface without using special projection screens (silver screens).

Sometimes this technique is described as a «super-anaglyph» because it is an advanced form of spectral-multiplexing which is at the heart of the conventional anaglyph technique.

Benefits: Infitec™ stereo imaging works on every white screen. No need for special non-depolarization screens (silver screens). By use of low gain screens stereo images become very homogeneous and very serene. Homogeneity is comparable to high quality mono projection. Very high channel separation (no ghost images at all).

Disadvantages: little distortion of colors

Price: medium (about 50 Euro – per glasses pair)

The technology is based on the idea of splitting an image into 2 pictures by taking only the red colors of a picture for the left and the blue color for the right eye.

Benefits: low cost, easy to use.

Disadvantages: distortion of colors - left and right eye images have different colors, poor quality of stereoscopy.

Price: low

Polarized 3D glasses create the illusion of three-dimensional images by restricting the light that reaches each eye (linearly and circularly polarization). To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters. The viewer wears low-cost eyeglasses which also contain a pair of orthogonal polarizing filters. As each filter only passes light which is similarly polarized and blocks the orthogonally polarized light, each eye only sees one of the images, and the effect is achieved.

Benefits: relatively low cost for clear imaging and collective work opportunity in VR.

Disadvantages: the light reflected from a motion picture screen tends to lose a portion of its polarization, stereoscopic equipment occupies a lot of space, and special expensive silver screen is required.

This technology is called “real-time simulation”. The realistic perception is achieved with the refreshing rate (the speed of a single frame computing) no less then of 24 frames per second and with the superior resolution.

In the modern market Trans-Force is the leader in offering a unique full-range of interaction based on real-time simulation combined with high-quality graphics on panoramic screen with stereo projection. The difference with other producers is in the multiple ways the visitor can interact with the virtual world. From a simple observer, the spectator turns into an active participant of the adventure getting involved in route decision-making, the steering, offering input in the spaceship systems and control of weapons, taking pictures of different virtual world creatures and making other manipulations.
