A spectacular waterfall 'Led' welcomes visitors in the Salesforce building

To perform this realistic simulation its creators, Obscura Digital and Fusion CIS, have used a Led screen of 32×4,5 meters with a resolution of 8,112×960 pixels that are integrated into the environment as if they were part of it.

With a spectacular waterfall is how you receive visitors in the building of Salesforce in San Francisco. A realistic simulation that has been integrated into the space forming part of the lobby.

This digital effect has been created by the creative studio Obscura Digital and Fusion CIS using a Led screen of 32×4,5 meters with a resolution of 8,112×960 Pixels. The waterfall, computer-generated, it is not presented as a background image but is part of the scene. Its installation has been commissioned by the company sna.

To produce the effect you were looking for, were specified 1.100 frames and while Renderstorm was in charge of physical processing, Fusion CIS focused on the challenges posed by simulations and lighting.

RealFlow was used (Next Limit Technologies) to create this dynamic physical simulation, since Fusion CIS has developed a complete library of methods and tools that expand its capabilities and allow management and control to achieve personalized results.

To carry out this project, two waterfalls were designed. A basic version that begins to flow gradually to become a complete waterfall that splashes against the doors of the lobby, So what, gradually, slows down to a stop; and, a second, which posed greater challenges as it begins with a waterfall that flows completely and then interacts with a set that deforms into steps, it looks like it comes out of the wall and backs off.

Obscura Digital provided the wall design as a digital archive, with dimensions adjusted to match the lobby wall, and also created the deformation of the geometry into levels for the second cascade. To achieve the exact level of detail, Fusion CIS designed a digital cascade system with four overlapping panels, they were gathered in a lighting file to create the entire waterfall. Each panel performs the simulation separately, allowing greater detail in the water than would have been possible if the waterfall had been made as a single unit.

The water in the simulation is poured over an edge and down. Fusion CIS designed a dynamic set of small cubes at the edge of the cliff, so water develops small internal channels that change and evolve, thus avoiding a featureless flat water wall. In addition, a set of forces was created around the lobby doors that allow water to flow naturally and dynamically.

The simulations were performed on several machines and the Fusion CIS team generated the 'surface' versions through a process called meshing. Each panel of water has been generated with between 50 and 100 millions of polygon meshes per frame, so that the total waterfall is composed of between 200 and 400 millions of polygons.
