Anti-Aliasing in HPS
Anti-aliasing refers to a series of techniques used to improve the appearance of geometry with jagged edges, while rendering a picture. Using anti-aliasing in a scene allows for smoother results, while incurring a performance penalty.
When using HPS there are two separate and independent anti-aliasing settings:
Screen anti-aliasing
Text anti-aliasing
Note that screen and text anti-aliasing are not mutually exclusive. It is possible to have only one or the other active, or to have them both active at the same time.
Not using anti-aliasing (both off) yields the best performance, and is useful for scenes where aliased geometry is acceptable, or when rendering to a device with very high pixel density. High-DPI devices (e.g. mobile devices, Macs with Retina screens, and PCs equipped with high resolution screens) naturally yield a smoother image than less pixel dense screens even when anti-aliasing is off.
