This tutorial discusses anti-aliasing / oversampling. It specifically looks at what it is using a simple demonstration in Photoshop. The Details tab has several parameters that control anti-aliasing, the Oversampling rate, the Block/Volume Subdivision Limit and the Pixel Detail Block Size. This first tutorial generally explains what the Oversampling rate is, but also discusses the other two parameters in general terms. This is in preparation for several tutorials that discuss changes in this area in the Design 3D 8.1 update.
Go here for a discussion on changes to how 8.1 handles anti-aliasing.
