Disney Developing Augmented Reality System Capable of Virtually Lighting Real-World Objects
A new Disney invention could eliminate traditional lighting, moving lighting effects to an augmented reality viewer.
The “Introducing Real-time Lighting Effects to Illuminate Real-world Physical Objects in See-through Augmented Reality Displays” patent application (US 2021/0097757 A1) published April 1, 2021 sheds some light on the invention. A shader and a light source generator are used to apply virtual illumination to physical objects viewed through an augmented reality (AR) display.
This system is able to map three dimensional objects in the real world. The shader identifies points on the object; those are the vertices. Those vertices are then connected to create numerous polygons, mapping the real-world object for the computer.
A computer-generated lighting source is then applied to the polygons identified by the shader. The rendered scene lighting is displayed on top of the real-world objects through the AR screen.
