A spectacular 'Led' water waterfall welcomes visitors to the Salesforce building

To make this realistic simulation, its creators, Obscura Digital y Fusion CIS, They have used a 32 LED screen×4,5 meters with a resolution of 8,112×960 pixels that integrate into the environment as if they were part of it.

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

This digital effect has been created by the creative studio Obscura Digital y Fusion CIS using a 32 LED screen×4,5 meters with a resolution of 8,112×960 pixels. At the waterfall, computer generated, It is not presented as a background image but is part of the scene. The company has been in charge of its installation SNA.

To produce the desired effect, they were needed 1.100 frames and while Renderstorm took care of physical processing, Fusion CIS focused on simulation and lighting challenges.

RealFlow was used (Next Limit Technologies) to create this dynamic physics 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 gradually begins to flow to become a full waterfall splashing against the lobby doors, and?, gradually, slows down to a stop; y, a second, which posed greater challenges since it begins with a waterfall that flows completely and then interacts with a set that deforms into steps, It seems to come out of the wall and retreat.

Obscura Digital provided the wall design as a digital file, with dimensions adjusted to match the hallway wall, and also created the tiered geometry warp for the second waterfall. To achieve the exact level of detail, Fusion CIS designed a digital waterfall system with four overlapping panels, which were put together in one lighting file to create the complete waterfall. Each panel performs the simulation separately, allowing greater detail in the water than would have been possible if the waterfall had been done as a single unit.

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

The simulations were run on multiple machines and the Fusion CIS team generated the ‘surface’ versions through a process called meshing.. Each water panel has been generated with between 50 y 100 millions of polygonal meshes per plot, so that the total cascade is composed of between 200 y 400 millions of polygons.
