Upgraded GPU Gives Airline Designers a Comprehensive View of the Cabin11 Mar, 2014 By: Adam Scraba
Switching to an NVIDIA Quadro K6000 graphics processing unit (GPU) improves model viewing and rendering at Zodiac Seats.
Zodiac Aerospace is a global company that designs and manufactures aerospace equipment and systems for commercial, regional, and business aircraft. One of its largest divisions is Zodiac Seats, an aircraft seat manufacturer with offices in California, Texas, France, Great Britain, and other locations worldwide. Its customers include such airlines as Cathay Pacific, Emirates, and Air France, as well as other global, regional, and private carriers throughout the world.
In addition to seats, Zodiac Seats also designs various economy and business-class cabin configurations, working to maximize the number of passengers that can comfortably fit into the cabin while complying with each airline’s specific requirements. The company recently implemented NVIDIA’s newest and most powerful graphics processing unit (GPU), the Quadro K6000, to improve rendering speed and capacity for its designers.
A Design Workflow Bottleneck
Zodiac Seats is continually bringing more of the product design, development, and manufacturing processes in-house in order to achieve a more fully integrated product concept-to-delivery lifecycle for its clients. Everything in an airplane is so interconnected — and so limited by space constraints — that Zodiac Seats’ designers and clients must be able to visualize the cabin as a whole in order to make the most informed design decisions. Photorealistic renders are critical to this decision process; they take the place of physical prototypes, which are expensive and time-consuming to create, and enable clients to see the big picture — the design of the entire cabin, complete with all its seats and other components. Achieving this type of visualization, however, has not always been possible for Zodiac’s design team.
Photorealistic renderings, which can be produced more quickly than physical prototypes, enable Zodiac designers and their clients to evaluate how the finished product will look. Click image to enlarge.
A typical project starts with designers using Dassault Systèmes CATIA 3D CAD design software to design all the external surfaces with which a passenger interacts, including seats, walls, floors, and in-flight entertainment systems. The designs — both of the seat by itself and of several rows of seats populated in a cross-section of the cabin — are then refined through multiple iterations in Bunkspeed 3D rendering software in order to test variations in color and lighting across the cabin and to achieve physically accurate, photorealistic imagery. From there, designers work closely with engineers to determine the optimal internal structure of seats and associated surfaces. Seat designs must accommodate integration with onboard elements including in-flight entertainment systems and beverage carts, and address concerns regarding ergonomics and passenger comfort.
One obstacle in this design process was that the designers’ previous workstations, which incorporated NVIDIA Quadro 2000 GPUs, couldn’t handle the amount of data required to work interactively with typical seat and cabin cross-section models. The resulting bottleneck forced the Zodiac team to reduce their designs down to wireframes for review before sending them to render. This process made it difficult for viewers to get the full picture — either an individual seat would be stripped of essential detail, or a cross-section would only show one small, simplified portion of the cabin. In addition, slow render times limited productivity, and time that could have been used more effectively on other tasks was wasted on minimizing designs to wireframe.
