Abstract
A graphics processing device may generate coordinates for vertices of graphics primitives in a view-space. Tiles are defined within the view-space and are associated with tile lists. Primitives and/or vertices which overlap a tile are determined. Tile lists comprise differentially encoded indices and/or spatial coordinates for overlapping primitives. The differential encoding may or may not be byte aligned. During tile mode graphics rendering, tile lists are utilized to reference vertex attributes and/or primitives. Graphics rendering comprises a tile binning phase and a tile rendering phase. The primitives may comprise a triangle and/or joined triangles that share one or more vertices. For multiple joined primitives, information about shared vertices may be encoded without repetition for each primitive. Coordinates and/or corresponding weights for new vertices are encoded in a tile list and utilized for interpolating properties of the new vertices based on attributes of the original vertices.
