What is FPS (Frames Per Second)?
FPS, or frames per second, is a measure of how fast an image is being rendered on a screen. The higher the FPS, the smoother the image will appear. For instance, a video game running at 60 FPS will appear much smoother than one running at 30 FPS.
In the field of 3D visualization, FPS is important for two main reasons: first, it affects how realistic and fluid the animation appears; and second, it can affect how much computing power is required to generate the animation. In other words, a higher FPS can result in a better-looking animation, but it may also require more processing power to generate that animation.
