To make this realistic simulation its creators, Obscura Digital and Fusion CIS, have used a 32 × 4 Led display, 5 meters with a resolution of 8.112 × 960 pixels that are integrated into the environment as if it were part of it.

With a spectacular waterfall as it greets 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 Creative Studio Obscura Digital Y Fusion CIS using an Led display of 32 × 4, 5 meters with a resolution of 8.112 × 960 pixels. Waterfall, computer-generated is not presented as an image of background but that form part of the scene. The company has been responsible of your installation SNA.

1.100 frames were needed to produce the effect that is sought, and while Renderstorm He was responsible for the physical processing, Fusion CIS focused on the challenges posed by the simulations and lighting.

RealFlow used)Next Limit Technologies) to create this dynamic physical simulation, because Fusion CIS has developed a complete library of methods and tools that extend its capabilities and allow management and control for custom results.

Two waterfalls are designed to carry out this project. A basic version that starts to flow gradually to become a complete waterfall that splashes against the doors of the lobby, and which gradually slows to a stop; and a second, posed major challenges since it begins with a waterfall flowing completely to then interact with a set that is deformed in steps, it seems that it comes out of the wall and back.

Obscura Digital provided the design of the wall as a digital file, with dimensions adjusted to coincide with the wall of the lobby, and also created the deformation of geometry in levels for the second waterfall. To achieve the exact level of detail, Fusion CIS designed a digital system of Cascade with four overlapping panels, which were gathered in a file of lighting to create the full waterfall. Each panel carries out the simulation separately, allowing a greater detail in the water than it would have been possible if the waterfall has been completed 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 on the edge of the cliff, so the water develops small internal channels that change and evolve, thus avoiding a wall of water even without features. In addition, created a set of forces around the lobby doors that allow the water to flow naturally and dynamic.

The simulations were conducted on several machines and Fusion CIS team generated versions of 'surface' through a process called mesh. Each panel of water has been generated with between 50 and 100 million of polygonal meshes by plot, so the total waterfall is composed between 200 and 400 million polygons.
