Pixomondo's Immersive LED Display Volume and Motion Platform Tour

Pixomondo's State-of-the-Art Display Volume

• 💡 Pixomondo has built a state-of-the-art display volume, a massive setup of LED screens used in virtual production, inviting the LTT team to explore its technology.
• 🚀 This technology replaces green screens, simplifying on-set lighting and eliminating post-production color correction, making productions more immersive for talent.
• 🖼️ The display features a main back wall at nearly 8K resolution, a 6K by 3K ceiling, and 2K by 2K side walls, all powered by Unreal Engine 5 (UE5).

Advanced Motion and Display Capabilities

• 🚗 The display volume is mounted on a motion platform capable of spinning a car and simulating various terrains using hydraulics and multiple axes.
• 💨 Side walls weighing one ton each are moved using an air-based counterweight system requiring only 80 PSI.
• ⚙️ The ceiling display is on a gantry, allowing it to be moved for different camera and lighting setups, especially for angled windshield reflections.

Gaming and Panel Technology

• 🎮 Gaming on the display volume proved challenging due to input latency and a low frame rate (24 fps), highlighting that it's built for film production, not gaming.
• 💡 The LED panels themselves offer near-instantaneous pixel switching, comparable to OLED, with incredible image quality and 1,500 nits of peak brightness.
• 🧐 The modular design allows for custom configurations and easier manufacturing/serviceability, with each cabinet made of four modules, and each module of four sub-modules to increase yields and lower costs.

The Pixo Akira System and Techno Dolly

• 🔊 The Pixo Akira system utilizes a massive hydraulic system with 16 physical axes to simulate vehicle movement, capable of tilting up to 12° and moving 26 cm vertically/laterally.
• ⚡ Individual wheel manipulation is achieved with 2.2 kW motors for rollers and 3.5 kW motors for 'dinkers' to simulate bumpy terrain, powered by a dual 75 horsepower electric pump system.
• 🎥 The Techno Dolly 25, one of only four in the world, offers frame-accurate camera movement with a 26-foot boom extension, programmed using keyframes and a custom software system.

Server Room and Networking Infrastructure

• 💻 The heart of the setup is the server room, housing render nodes with two Nvidia ADA 6000 GPUs, Threadripper CPUs, 256GB of RAM, and 8TB of NVMe storage per machine.
• 🌐 Synchronization cards and a GPS antenna ensure all GPUs communicate precisely, preventing screen tearing and maintaining perfect sync across the display.
• 🔌 Data flows via fiber optics to Netgear AV switches, which split 10Gb links into 2.5Gb links powering the display panels, with PoE++ enabling the motion capture camera system.
