“To celebrate the first day of term at Hogwarts, Pottermore launched Welcome to Hogwarts, a fully interactive WebGL experience that gives users the chance to explore a 3-D version of the school for witchcraft and wizardry. The experience enables millions of Pottermore fans to immerse themselves in a fantastical world, discovering information and exploring the layout of Hogwarts and its surrounding areas. To ensure a seamless user experience across a range of devices, we did a lot of performance optimization and used a stylized aesthetic. We also created project-specific tools, such as a hot spot placement tool and an illustration platform, enabling Pottermore to continue to inject new content over time, encouraging users to come back and keep exploring.”
