Claim 9:
10. A system for predefining an entryway at a virtual boundary of an extended reality (XR) space contained within a real environment, for an object entering or leaving the XR space; the system comprising:
one or more processors; and
logic encoded in one or more non-transitory media for execution by the one or more processors and when executed operable to:
access a previously generated spatial mapping mesh (SMM) for the real environment, including physical elements and open areas throughout the real environment;
access a previously generated sealed space mesh (SSM) in which the XR space is defined, the SSM being bounded by virtual boundaries, and including all physical elements present in that space;
analyze polygons in the SMM to identify a first SMM subset of polygons representing vertical surfaces of all physical elements within the SSM, and analyze polygons in the SSM to identify a first SSM subset of polygons representing virtual wall boundaries of the XR space;
filter polygons in the first SMM subset and the first SSM subset according to a first set of criteria, to yield a second SMM subset and a second SSM subset respectively;
collide polygons from the second SMM subset with polygons in the second SSM subset to discard each polygon in the second SSM subset that overlaps any polygon in the second SMM subset by greater than a predetermined percentage threshold, yielding a third subset of SSM polygons;
define one or more groups of SSM polygons within the third subset such that polygons in each group are connected or spaced apart by less than a predetermined distance; and
select one of the groups of SSM polygons as defining the entryway;
wherein the entryway is defined in advance of user interaction with virtual elements in the XR space.
