Morphable 3D-Mosaics: A Hybrid Framework for Photorealistic Walkthroughs of Large Natural Environments

Figure 7

We show rendered views of a morphable 3D-model during the transition from one key-position (corresponding to image ${ℐ}_k$ in Figure 4) to another key-position (corresponding to image ${ℐ}_{k+1}$ in Figure 4). On t(a) we show the result produced when no geometric morphing is applied to points in $\overline{\mathrm{\Psi }}$ (notice the resulting discontinuity, i.e., hole). On (b) we render the same view, but this time we also apply geometric morphing to points in $\overline{\mathrm{\Psi }}$ (no discontinuities/holes exist in this case). A zoomed version of this view is also shown on (c). Although, as mentioned, there is no geometric discontinuity, yet there is a difference in texture resolution between the left part of the image (points in $\overline{\mathrm{\Psi }}$) and the right part (points in $\mathrm{\Psi }$), since only points of the latter part are morphed photometrically.
