SPIERSview supports hardware anti-aliasing (jagged edge reduction) through OpenGL; not all hardware will support this facility, and on some systems antialiasing will not work in QuadBuffer Stereo mode. Anti-aliasing is off by default, but can be set to x2, x4, x8 or x16 using the view menu. Higher anti-aliasing settings improve image quality by smoothing jagged edges, but reduce performance and may use more memory. Consider turning anti-aliasing on before performing screen captures or generating animations. Changing the anti-aliasing mode forces a full resurfacing of all objects; for compact or presurfaced SPIERSview files (.spv format) this may take a considerable amount of time.
