Abstract

We conducted experiments with 38 users who interacted with 3 progressively streamed and rendered 3D meshes in order to study their tolerance levels for network data rate and delay. Our study shows that over 90% of users can tolerate a data rate of 80 KBps and above (when the delay is 400ms) and over 95% of users can tolerate delay up to 1 second (when the data rate is 100 KBps). Our study shows that data rate and delay tolerance levels do not vary significantly among the three meshes we used.
