Progressive compression of arbitrary textured meshes - Supplementary Materials

To validate our edge selection strategy, we present here the rate distortion curves obtained using different edge selection metrics: Hausdorff distance wgc, texture seam deviation wt and the combination that we propose wgc + wt . We use the multiscale SSIM metric presented in the paper to evaluate the quality of the obtained levels of detail (the texture map is kept in its highest resolution for this experiment). Figure 1 shows that the wgc +wt selection clearly improves the visual quality of the LoDs compared to wgc. Whereas, wt seems to be insufficient as, even if texture fidelity is visually important, mesh geometry still be crucial.
