With a spectacular videomapping Guayaquil commemorates its 200 years of independence

Under the name 'The Mapping Route', six of the most emblematic buildings of the Ecuadorian city served as a canvas to make the projections. Eight computers with Christie 3DLP technology were used for its execution.

The facades of six emblematic buildings of Guayaquil (Ecuador) have served as the stage for the realization of a spectacular videomapping show that has been projected to commemorate the bicentennial of the independence of the city.

The Mapping Route, as the event was called, was developed for a week with 3DLP technology projectors from Christie by the hand of the Ecuadorian rental company & staging 3Laser.

This project was part of the program of activities, which included a show with 300 Drones, organized by the Municipality of Guayaquil in conjunction with the Municipal Public Tourism Company.

One of the sites chosen to carry out the mapping was The Point, than with their 137 meters high is the tallest building in the city and an architectural icon due to the spiral design of its structure. Here a projection of one hundred meters high was made by 30 meters wide and it showed animated graphics of the change of the city and other representative elements of various eras of the city, like the railway, river trade and architecture.

Another building, whose façade served as a projection canvas, was the Municipal Palace of Guayaquil, in this case an area of 80 was used×30 metre, and in this episodes of the Buenos Aires foundation were shown, the invasion of pirates, the process of liberating deed, and the cultural and ethnic diversity of the city.

It was also projected on the Clock Tower, another of the emblematic symbols of the city, and about the Metropolitan Cathedral of Guayaquil. Each of the screenings was accompanied by a performance by a popular music artist.. How the capacity had to be reduced by the pandemic, all mappings were broadcast live via social media.

To fit images on uneven surfaces, 3Laser used the photographic technique. "It is very fast and allows us to map all the details in the perspective of the projectors", explains Ángel Cuesta, director of the rental company. "First we put together the structure of the projectors, then we take the photograph and make a projection of the area to be covered with which we calculate the pixels. With the help of laser meters, we see the actual surface and calculate the zoom of the lenses from the projection site. We always try to go as far as possible so as not to cover the public with the projection scaffolding".

3Laser used eight projectors of 20.000 Lumens of Christie 3DLP technology that were moving daily to the different buildings, since one mapping was carried out per day. A team of six 3Laser technicians was in charge of the movements and management of the teams..

"In that sense., Christie projectors are very reliable", says Ángel Cuesta. "We take them on tour from show to show and they're always ready to work.. We only change the air filters and lamps from time to time, and are able to operate for hours without heating or failure. In addition, setup steps are short and fast and its color performance is unique and remains stable over time. Also its size and weight are ideal to place in uncomfortable places, and can work in portrait mode”.

Angel Cuesta also praises the projector's control hardware and firmware. "It's very reliable.. And not to mention the network control tools and the Twist module that help us to use all the resolution and color, which gives realism to 3D effects. likewise, lenses are compact and have integrated zoom and focus, in addition to dust filters that extend the life of the equipment”.

Given the result obtained with these projections, Mayor Cynthia Viteri plans to install The Mapping Route as an event to be repeated every year for the enjoyment of citizens and tourists.
