The dome surface consists of two shields: external decorative cover and internal surface, supported by a firm stricture between them. The internal projection surface of the dome technologically does not provide suspension elements and the internal shield is held in the air due to the difference in pressure in the aerodynamic space between the outside dome and the internal surface.

The technical difficulty in the implementation of the dome projection consists in need of an exact balance between the volume of the light flux, the pixel size and the scheme of dome lighting by the projectors. On the dome, the projectors interfere with the overall quality of the image rather than they complement each other. Incorrect angle and the position of one projector can create insuperable difficulty in putting some of the segments of the dome together or a pronounced difference in color and contrast. It is impossible to fix this manually on an on-going basis.

To secure a fairly accurate setup, calibration by color, opening and overlapping of projectors on each other, we used Screenberry media server system, which works in a following way: a camera with a wide lens, which is installed in the center of the dome, is used for calibration in a completely dark room. It photographs the whole dome from the bottom upwards and sends data to the server and the system itself determines the necessary parameters for each projector.

Apart from the dome projection, we created a laser show as a part of the presentation. We put 20W Kwant laser projection systems of Spectrum series around the perimeter, 11 of them with 30kpps scanners, one with a new scanner of 90kpps.

The main part of the laser show fell on the car reveal moment: at the end of the projection show hundreds of laser beams pearced the space and lighted up the whole dome surface, setting the stage for the car itself.

We could not refuse the light, since the presentation and on-line stream was also an important part of the show. But inside the dome there is nothing to hang the light on and erection of any structures is excluded, as all objects create shadows on the surface of the dome and interfere with the opening of the projectors. Low floor mounting was excluded too: it would blind the audience and could not provide the desired overall look of the central podium during the presentation.

The solution was custom-made. We placed the light setup on the hoisting and lowering electronic elevator systems. During the show the light was at a mark of 2.5 meters and did not interfere with the opening of the projectors. By the presentation part, we raised the elevators to a height of over 5 meters for uniform illumination of the car and a speaker. This allowed to turn the dome from the multimedia space with the show into the stage for the presentation.

A rolling circle with a diameter of 5.5 meters held a car and a speaker, presenting for the whole audience around him. We used laser scanners that read the surface and were programmed to track all objects at a height of human scale in the space of internal rolling circle.

Real time tracking exchanged data with the light console and automatically arranged the position of the lights and the level of illumination of the speaker. The laser system was connected to the GrandMA light controller via the standard PSN protocol. We calibrated the positions of the devices in the light controller and got information about tracking from the scanners. In this case, the software itself was also custom. With the help of the incoming DMX trigger, it allowed to make a very good effect of fade-in and fade-out at the moments when a person was entering the area of scanners operation and leaving it.
