1. A method comprising:
generating, by a computing device, a clipping tree that includes a root node and a node for each clipping group included in a layer of an input render tree;
generating, by the computing device, a segment buffer having rows that each represent coverage of a branch of the clipping tree and columns that each represent coverage of a level of the clipping tree;
mapping, by the computing device, the segment buffer to a two-dimensional array; and
computing, by the computing device, coverage for a clipping object of a clipping group included in the layer of the input render tree based on an identifier of a row of the two-dimensional array.
