20Difficulties of using the restored building as a screen With projection mapping, images must be created in line with the building that will act as the screen. Mr. Moriuchi said that the most important thing, therefore, was to first decide on the format.For this project, images were produced to overlap with the Tokyo Station building, which had been created by CG based on design drawings. A projection experiment was then conducted using a 1:200 scale model. In the case of animation, things seen on a screen and things projected as a three-dimensional object create a very different impression. If a projec-tion experiment using a 1:200 model is not conducted with a firm grasp of spatial concerns, then good images will not be created.However, this presented a variety of problems. The design drawings and actual Tokyo Station building were very different.“A 3D scan of the building was necessary rather than basing the images on drawings, but that could not be done because the station building itself was under construction. In the end, images were created based on drawings, and minor adjustments were made to the final results while making adjustments at the station itself” (Mr. Suzawa).Adjusting the colors was also hard work. The black, white and red were disordered - black roof, dark-red brick wall, white wall joints and white window frames and curtains. “Thanks to the red brick and white joints, it looked stripy ruining its stereoscopic effect. So we assembled a team to create a color collect program.” (Mr. Moriuchi)“Specifically, we created a color mask to make red parts brighter and white parts darker. This was done with AfterEffects.” (Mr. Suzawa)In addition, other problems were discovered two weeks before the event, such as colors changing when projected and the CG looking unnatu-ral; conversely, when the content was too detailed.“Near-4K images were created at a frame rate of 29.97fps and they had to be revised. Other things happened like the creator losing interest and going home.” (Mr. Suzawa)What images should be used? The significance of the project Now that the “TOKYO STATION VISION” project had overcome a variety of difficulties, a lot of thought also went into the expressed images.Considering that the station is Japan’s main terminal station, Mr. Moriuchi initially envisaged images that would unravel the station’s history spanning from its national railway to JR history. Famous trains and the development of the station’s surrounding area were also considered. However, as discussions with the East Japan Railway Company progressed, talk turned to content that would “appeal to many people of all generations”, so they aimed for something that everyone would enjoy and entertainment that would show what projection mapping means.Based on the idea that Tokyo Station has many different faces as far as
