In an example, a method for rendering a 3-D scene of graphical data into a 2-D scene may include dividing 2-D space used to represent the 3-D scene from a viewpoint into a plurality of tiles. The 3-D scene may include a plurality of primitives. The method may include generating visibility information for a first tile of the plurality of tiles. The method may include modifying the visibility information for the first tile to generate modified visibility information for the first tile. The method may include generating the 2-D scene using the modified visibility information for the first tile.
