Abstract

In implementations of systems for efficient rendering of clipping objects, a computing device implements a clipping system to generate a clipping tree that includes a root node and a node for each clipping group included in a layer of an input render tree. The clipping system generates 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. The segment buffer is mapped to two-dimensional array, and the clipping system computes 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.
