Last week I visited Montréal’s Société des Arts Technologiques, where I heard an amazing TouchDesigner dome performance (above) by Vincent Houzé, learned all about immersive sound from Jean-Marc Jot, heard an amazing 360°-video-plus-AR demo by Zack Settel, heard an impressive 3D speaker by Peter Otto, learned how to build AR iOS apps using ARkit and Unity with Isaac Cohen, experienced 3d photogrammetric point clouds in a beautiful VR experience by Priam Givord, and had lots of fun conversations about the future of XR.
