The setup runs from a single computer rendering 8xHD at a resolution of 7680×2160 at 60fps spanning an area of 10m2.
To achieve this high speed rendering we created two separated OpenGL contexts for each graphic card (AMD W7000) and off course used a lot of threads to do all the slow image and data loading. We also used a Linux server where a Node.js CMS did most of the preprocessing of text,images and video.
Using a DXT convertor for video preprocessing and phantom.js to render text compositions to image files. Back to the project.
