This Anti-aliasing option concerns oversampling, which is a method used to determine the color of each pixel viewed by the current camera.

The resolution of the scene is not dependent on the number of pixels or scan lines. The unit of measurement is much smaller but must be adapted to pixels to be viewed by the current camera, and shown on the computer screen.

Use this field to enter the number of times each pixel is sampled to determine the pixel’s color. The higher the number of samples the more accurate the pixel color, but the longer it takes to render.
