As Ziva has stated: “The ZRT Face Trainer is built on a comprehensive library of 4D data and proprietary machine learning algorithms. Within 1 hour, your character mesh is injected with the game industry’s best tech.” Here are also the key features of ZRT Face Trainer. The ZRT Face Trainer is built on a library containing over 15TB of 4D scan data. ZRT face puppets can express over 72,000 training shapes, as well as novel face poses. ZRT face puppets are only 30MB at runtime and run at real-time frame rates (3ms/frame on a single CPU thread).
