INDUSTRY GLOSSARY
What is Trans-Force 5D Interactive attraction? In order to answer this question please find below the brief industry glossary.
3D
3D (three-dimensional) imaging or stereoscopic imaging is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a movie, or other two dimensional image is created by presenting a slightly different image to each eye. To achieve 3D vision the viewer wears special glasses.
Today there are several techniques of 3D imaging creation:
Passive stereo
Active stereo
3D HD Projection
Stereoscopic three dimensional high definition projection. It can be either
video projection (pre-rendered) or real-time simulation.
4D
The addition of special effects to a theatrical presentation to create a «fourth dimension» - the sensation of tactile experience: scent, temperature, touch. Examples: Beetles tickle the legs of unsuspecting cinema-goers, the wing beat of a gigantic dragon breezes through the rows of seats and spiders descend from the ceiling.
4D+
Interactivity is the possibility to interact with the virtual world in real-time mode. The most commonly used ways of interaction are: driving a car simulator (wheel), firing targets (laser gun). The limitations in interaction are explained by the type of software the producers use.
Full interaction is based on real-time graphics. In contrast to 3D/4D cinemas this technology is based on modeling the image in real time rather than recorded in advance (pre-rendered). 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.
Nowadays only Trans-Force can suggest 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.
5D
Moving seats or motion platform. Motion effect is described by # of DOF - Degrees of Freedom - refers to the number of directions or types of motions a simulator base will operate on. Minimum DOF – 1, maximum (full motion) – 6.
6D
Invented by Kraftwerk and refers to mobility of the attraction when it is placed on a special trailer and can travel all over the country as a circus.
Screen shape
There can be several types of screens:
-flat
-curved
-panoramic with up to 180° - used by Trans-Force attraction
-circular 360°
-spherical (semi-spherical and full-dome)
The most primitive one – is the flat screen that uses only 1 projector. The most advanced is full-dome that may use more than 20 projectors. In case of curved and spherical screens the special hardware or software connects the segments projected by different projectors on the screen without visible joints with 1-5° overlap.
