Antialiasing is a technique you can use to reduce the appearance of stair-step pixels when drawing any line that is not exactly horizontal or vertical. In three-dimensional scenes, this artifact is most noticeable on the boundaries between polygons of different colors. Antialiasing effectively blends the pixels at these boundaries to produce a more natural look to the scene.
Microsoft® Direct3D® supports two antialiasing techniques: edge antialiasing and full-surface antialiasing. Which technique is best for your application depends on your requirements for performance and visual fidelity.
The section below shows how to use special effects to simulate or use antialiasing.
