To date, almost all work within the field of 3-D animation has focussed on raising perceptual appeal to an adequate level. However, it is a non-trivial task to match the requirements of real-time streams to the reality of the Internet. One of the key problems that must be addressed is that of how best to conceal errors in the event of packet loss. Thus we present the results of experiments designed to evaluate the effect of different possible schemes under different conditions of loss. We conclude that frame insertion methods show good performance at low loss rates, but that frame interpolation methods exhibit better performance at both low and high burst loss rates, though at the cost of added delay and complexity. Visualised traces subjectively validate these results, by exhibiting smoother animation and reduced artifacts on the animated wireframe models.
