1. A method of processing mesh data for processing an audio signal for audio rendering in a virtual reality (VR) space, the method comprising:
receiving mesh data configured to define geometry of a certain space, wherein the mesh data comprises data regarding three-dimensional (3D) coordinates of points for configuring spatial information of the certain space;
processing the mesh data by identifying outermost points among the points;
rendering the audio signal based on the processed mesh data; and
outputting the rendered audio signal, wherein
each of the 3D coordinates comprises an X coordinate, a Y coordinate, and a Z coordinate, and
the processing of the mesh data by identifying the outermost points among the points comprises:
defining a coordinate having a minimum value among X coordinates of the 3D coordinates as a minimum X coordinate;
defining a coordinate having a maximum value among the X coordinates of the 3D coordinates as a maximum X coordinate;
defining a coordinate having a minimum value among Y coordinates of the 3D coordinates as a minimum Y coordinate;
defining a coordinate having a maximum value among the Y coordinates of the 3D coordinates as a maximum Y coordinate;
defining a coordinate having a minimum value among Z coordinates of the 3D coordinates as a minimum Z coordinate;
defining a coordinate having a maximum value among the Z coordinates of the 3D coordinates as a maximum Z coordinate; and
identifying the outermost points based on the minimum X coordinate, the maximum X coordinate, the minimum Y coordinate, the maximum Y coordinate, the minimum Z coordinate, and the maximum Z coordinate.
