Game apparatus, storage medium and computer program

A game apparatus, a storage medium and a computer program, capable of reducing all processing of generating an image of a predetermined object in a virtual three-dimensional space without providing a substitute model for the predetermined object in the virtual three-dimensional space. The game apparatus comprises: an arrangement position setting section (212) for setting an arrangement expected position (20a) of a predetermined object in a virtual three-dimensional space; an image generation section (250) for generating a two-dimensional space image viewed from a virtual camera (10), based on the virtual three-dimensional space including the arrangement expected position; an image insertion section (254) for inserting a two-dimensional object image (20) expressing the predetermined object into a position corresponding to the arrangement expected position, of the two-dimensional space image; and an execution section for executing a predetermined game by displaying the two-dimensional space image including the two-dimensional object image.
