1. A system comprising a first information processing apparatus and a second information processing apparatus capable of communicating with each other,
wherein
the first information processing apparatus comprises a first controller configured to: acquire three-dimensional point cloud data including multiple vertices each having three parameters of x-, y-, and z-coordinates and a combination of the x- and y-coordinates is different from vertex to vertex,
and convert the three-dimensional point cloud data into two-dimensional point cloud data in which each of the multiple vertices has two parameters, a parameter m with a different value for each combination of the x- and y-coordinates, and the z-coordinate,
and the second information processing apparatus comprises a second controller configured to:
generate mesh data, using the two-dimensional point cloud data and information indicating correspondence between the combination of the x- and y-coordinates and the parameter m, and
wherein when generating the mesh data, the second controller is configured to not form a polygon including two vertices, in a case in which the z-coordinate of one of the two vertices is within a range of a reference value z0+Δz, and the z-coordinate of the other of the two vertices is outside the range of the reference value z0+Δz.
