Computer, method, and computer-readable medium for rendering extended reality based on a determined coordinate conversion equation

Abstract

A computer according to the present disclosure includes a processor, and a storage device storing one or more programs that, when executed by the processor, cause the processor to: calculate first coordinates in a first coordinate system of a 3D object rendered in an XR space defined by the first coordinate system, calculate second coordinates in a second coordinate system different from the first coordinate system of a device tracked by a tracking system related to the second coordinate system, and calculate a coordinate conversion equation that converts coordinates of the second coordinate system into coordinates of the first coordinate system based on the first coordinates and the second coordinates, in response to a predetermined operation by a user. The computer enables easy use of a device compatible with a second tracking system in an XR space according to a first tracking system.
