0. Terminology

In this wiki, the same terminology defined within the paper is used. For convenience, the terminology is defined here:

• Animation Update Frequency (AUF) / Animation Rate - When we refer to either of these terms, we refer to the rate at which an agent has it's animations updated. Under normal circumstances, everything in a scene has it's animations every frame. In such a case, the animation rate is the same as the scene's frames-per-second (FPS). When we intentionally lower the animation rate of a model below the scene's FPS, we call that (animation) foveation.
• Foveal Area - For the purposes of this project, the foveal area is defined as the area around the user's focus point which is NOT foveated - within this foveal area, all animations proceed as normal.
• Foveation Method - this refers to either Full Stop or Dynamic Foveation, described below.
• Full Stop method - One of the two methods of foveation used in this project. Here. everything outside of the foveal area has its animations completely halted. The foveal area is the only foveation value we modify.
• Dynamic Foveation - One of the two methods of foveation used in this project. Here, everything outside of the foveal area has it's animation rate based on an equation, best described within section 3.1 of the paper or on the website.
• Foveation Factor - An arbitrary variable used in the calculation of a model's animation rate in the Dynamic Foveation method. The higher the number is, the more aggressive the drop-off from fully-animated to halted animations. For reference, our user tests had this value between 0.1 and 2.1.
