Abstract

The graphics community has understood line antialiasing reasonably well for many years. Many papers have been written on the subject, but none of them have offered a complete solution. This paper explains all of the details of a well behaved hardware algorithm used in the SparcStation ZX that, although imperfect, works very well in practice. The paper discusses tradeoffs at each point and the reasoning that went into the decisions that were made.
