Providing apparatus, providing method and computer readable storage medium for performing processing relating to a virtual viewpoint image

A providing method comprising:

• associating information on a type of an imaging target captured by a plurality of imaging apparatuses with information on a a density of elements forming three-dimensional geometric data generated based on a plurality of captured images obtained by the plurality of imaging apparatuses and used to generate a virtual viewpoint image;
• receiving a data request from a communication apparatus;
• and
• providing, to the communication apparatus, three-dimensional geometric data corresponding to the density of elements which is determined based on a type of an imaging target in accordance with the received data request and the associated information.
