A picture rendering method, a storage medium, and an electronic apparatus are provided. The method includes: obtaining one or more target images for a two-dimensional (2D) virtual scene, each of the one or more target images including a background, a character object moving in the background image, and a target object located at a fixed position in the background; determining a first depth value of a first pixel on the target object in the background by using a depth offset indicated in a depth map corresponding to the target object, the depth map recording a depth offset of each first pixel on the target object; obtaining a second depth value of a second pixel on the character object moving to a target display position; and rendering the one or more target images according to the first depth value and the second depth value.

A method and system for culling a patch of surface data from one or more tiles in a tile based computer graphics system. A rendering space is divided into a plurality of tiles and a patch of surface data read. Then, at least a portion of the patch is analysed to determine data representing a bounding depth value evaluated over at least one tile. This may comprise tessellating the patch of surface data to derive a plurality of tessellated primitives and analysing at least some of the tessellated primitives. For each tile within which the patch is located, the data representing the bounding depth value is then used to determine whether the patch is hidden in the tile, and at least a portion of the patch is rendered, if the patch is determined not to be hidden in at least one tile.

Methods and primitive block generators for generating primitive blocks in a graphics processing system. The methods comprise: receiving transformed position data for a current primitive, the transformed position data indicating a position of the current primitive in rendering space; determining a distance between the position of the current primitive and a position of a current primitive block based on the transformed position data for the current primitive; determining whether to add the current primitive to the current primitive block based on the distance and a fullness of the current primitive block; in response to determining that the current primitive is to be added to the current primitive block, adding the current primitive to the current primitive block; and in response to determining that the current primitive is not to be added to the current primitive block, flushing the current primitive block and adding the current primitive to a new current primitive block.

An information processing device (20) includes: a specifying unit (23A) that specifies, from a plurality of pieces of layer data capable of expressing object light of a three-dimensional object in a stepwise manner, an occlusion region that is lost due to a foreground image of layer data of another hierarchy; and a modifying unit (23B) that modifies at least one of an amplitude or a phase in layer data at a boundary with the occlusion region that has been specified so that leakage of the object light to the outside of the occlusion region is suppressed.
