Abstract
Depth sensing measurements are performed for an area in all directions surrounding a user. Based on the depth sensing measurements, a horizontal plane the area, as well as a plurality of obstructions in the area are identified. A three-dimensional shape representing the maximum volume of contiguous open space is generated based on the horizonal plane and the plurality of obstructions. The three-dimensional shape is then truncated to create a maximally sized convex shape. The largest possible play area is then constructed using the convex shape.

A method for configuring a virtual reality play area, the method comprising:
- performing depth sensing measurements of an area in all directions surrounding a user;
- identifying, based on the depth sensing measurements, (a) a horizontal plane of the area, and (b) a plurality of obstructions in the area;
- generating a three-dimensional shape representing a maximum volume of contiguous open space in the area based on the horizonal plane and the plurality of obstructions;
- truncating the three-dimensional shape to create a maximally sized convex shape;
- and
- constructing the largest possible play area using the convex shape.
