Abstract

The disclosure relates to a graphics module for rendering a bidimensional scene on a display screen comprising a graphics pipeline of the sort-middle type, said graphics pipeline comprising: a first processing module configured to clip a span-type input primitive received from a rasterizer module into sub-span type primitives to be associated to respective macro-blocks corresponding to portions of the screen, and to store said sub-span type primitives in a scene buffer; a second processing module configured to reconstruct the span-type input primitive starting from said sub-span type primitives, the second processing module being further intended to implement a culling operation of sub-span type primitives of the occluded type.
