Oversampling (Antialiasing) - Blender Tutorial

Home » Tutorials » Blender Tutorial Directory » Oversampling (Antialiasing)

A computer generated image is made up of pixels, these pixels can of course only be a single colour. In the rendering process the rendering engine must therefore assign a single colour to each pixel on the basis of what object is shown in that pixel. This often leads to poor results, especially at sharp boundaries, or where thin lines are present, and it is particularly evident for oblique lines. To overcome this problem, which is known as Aliasing, it is possible to resort to an Anti-Aliasing technique. Basically, each pixel is 'oversampled', by rendering it as if it were 5 pixels or more, and assigning an 'average' colour to the rendered pixel. The buttons to control Anti-Aliasing, or OverSAmple (OSA), are below the rendering button in the Render Panel (Render Panel.). - View Tutorial »
