Abstract :
We propose the use of high-degree resampling filters for improved temporal antialiasing, or as the result is often called motion blur. Without temporal antialiasing, strange effects can occur within an animation, for example, wheels can appear to spin backwards at a certain speed. In a typical effort to overcome this, the camera shutter is left open over some period of time during the frame, leading to temporal box filtering. Even with a temporal box filter, aliasing can still occur. We show how a high-degree resampling filter, such as the Gaussian or cubic-spline lead to superior results in all cases, without the need for constant scrutiny and hand tweaking on the part of the animator
