Abstract
The goal of this work was to improve computer graphics by better understanding how internal rendering parameters affect the visual perception of animation. The scope of our work was constrained to the perception of object motion in animated sequences, specifically the motion blur effect that is generated to mimic the shutter and exposure of a film camera. Although this motion blur occurs as a natural consequence in real-world cameras due to the nonzero time needed for the image to be fully exposed, it is generated artificially through a variety of techniques in computer graphics in order to make the generated animation appear more realistic. In this work, we constrain the scope of our examination of motion blur to ray-traced rendering. We examine in detail the perceptual aspects of different techniques for generating ray-traced motion blur via experiments designed to isolate the various parameters in order to determine their effectiveness.
