AWS has announced Amazon Sumerian, a new Web-based platform to help developers quickly design and deploy VR, AR and 3D applications without the requirement for complicated tools and training. The platform lets developers build realistic VR, AR or 3D environments, populate them with animated characters and 3D objects, and create scripts to determine how they interact with users of a particular application and with each other. Sumerian is compatible with head-mounted displays, Web browsers, mobile devices and digital signage.
