each cell of a coarse c grid, a texxel program encodes several layyers of locally sppecialized graphiics primitives, too enable rendering of genneral vector grap phics over arbitrrary surfaces, as well as efficientt antialiasing. WWe encode a brooad class of vect tor graphics in a randomly accesss ibble format. Ourr approach is to create c a coarse ggrid in which eacch ccell contains a teexel program — a locally speciialized descriptioon oof the graphics primitives ove erlapping the ceell. These texxel pprograms are intterpreted at runti ime within a proogrammable pixxel sshader. Advanttages include coherent c low-ba andwidth memory aaccess, efficient iinter-primitive antialiasing, a and the ability to maap ggeneral vector grraphics (includin ng strokes) onto arbitrary surfacees. WWe present a faast construction algorithm, andd demonstrate thhe sspace and time eefficiency of the representation oon many practiccal eexamples.
