Non-transitory computer-readable storage medium having game program stored therein, game system, game processing method, and game apparatus

A game system comprising a processor, the processor being configured to:

• control a player character object and a virtual camera in a virtual space in which at least the player character object is placed and a back object is placed on a depth side with respect to the player character object;
• render the virtual space in a frame buffer with orthographic projection and by performing a depth test;
• determine a degree of hiding for each pixel on the basis of a hiding determination method based on SSAO (Screen Space Ambient Occlusion), the hiding determination method being a method in which, when comparing each of depth values of a plurality of sampling points set around a position, in the virtual space, corresponding to each pixel with a depth of a corresponding position in a depth buffer, a first offset in a predetermined direction is added to a position of the sampling point, and the comparison is performed;
• and
• further render a shadow at a pixel, in the frame buffer, corresponding to a portion for which the degree of hiding is determined to be high.

A game processing method executed by a processor of an information processing apparatus, the game processing method causing the processor to:

• control a player character object and a virtual camera in a virtual space in which at least the player character object is placed and a back object is placed on a depth side with respect to the player character object;
• render the virtual space in a frame buffer with orthographic projection and by performing a depth test;
• determine a degree of hiding for each pixel on the basis of a hiding determination method based on SSAO (Screen Space Ambient Occlusion), the hiding determination method being a method in which, when comparing each of depth values of a plurality of sampling points set around a position, in the virtual space, corresponding to each pixel with a depth of a corresponding position in a depth buffer, a first offset in a predetermined direction is added to a position of the sampling point, and the comparison is performed;
