Texel programs for random-access antialiased vector graphics
Diego Nehab, Hugues Hoppe · 2007
We encode a broad class of vector graphics in a randomly accessible format. Our approach is to create a coarse grid in which eacch cell contains a teexel program — a locally speciialized descriptioon of the graphics primitives ove erlapping the ceell. These texxel programs are intterpreted at runti ime within a proogrammable pixxel shader. Advanttages include coherent low-ba andwidth memory access, efficient inter-primitive antialiasing, and the ability to maap general vector grraphics (including strokes) onto arbitrary surfacees. We present a faast construction algorithm, and demonstrate thhe space and time efficiency of the representation on many practical examples.
