3D holographic projections are also called virtual image technology. It is a type of 3D technology where the image, video is projected on a certain surface and viewed without the use of 3d glasses. The surface should be invisible to the eye, ie as invisible as possible to achieve the effect of three-dimensionality, ie the appearance of objects in space. This technology brings an atmosphere of reality and illusion, the effect is very attractive. In order to achieve the full effect, the controlled conditions of darkness and distance of the audience from the position of at least 2 meters must be respected. There are several versions of the hologram: on foil, plexiglass, tulle, hologram in prism. Depending on which version we use, there are different image sources (projector, led display, laser). The material shown is specially prepared in 3d, by animation and image processing, adding effects as well as adding sound effects.
3D video / projection mapping is a technique for projecting animated video material that transforms static surfaces into interactive 3D displays, projecting complex 3D structures, objects and animations onto different surfaces. Mapping is done on objects (buildings, cars, people, models) that have a role in telling the story and creating the dynamics of the projection. Mapping can also be interactive if we include actors, performers, dancers in the story, who complement the background animation with their movements and facial expressions. Sounds / music are an indispensable part of mapping and together with the video they form a whole so that the viewer gets sounds along with the image so that the effect is complete. For a quality mapping performance, appropriate surfaces are needed, as well as controlled dark conditions. For external mapping projections on larger surfaces, walls, buildings, projectors with a power of 20,000 ans and more are used, while when mapping people, models, cars, slightly weaker projectors from 7,000 ans to 15,000 ans are used. Adaptation of the material to the surface is performed through appropriate licensed programs.
Beamvertising is, simply said, the projection of video and animated commercials on the facades of buildings from moving vehicles. The projected material can consist of various combinations, such as recorded video material and attractive 3D animation, as was the case in this Croatian premiere. For these purposes, the projector was located in the vehicle and projected the material onto the surfaces along which the vehicle passed. To make the experience complete, the sound that accompanies the advertisement is used. The real effect of Beamvertising is achieved when the vehicle moves through the city streets, while the advertising content with its size attracts the attention of a large number of people.
