3.10. Visual Modeling
In the previous sections, we explained how the camera motion and calibration and the depth estimates for (almost) every pixel could be obtained. This yields all the necessary information to build different types of visual models. In this section, several types of models are considered. First, the construction of texture-mapped 3D surface models is discussed. Then, a combined image- and geometry-based approach is presented that can render models ranging from pure plenoptic to view-dependent texture and geometry models. Finally, the possibility of combining real and virtual scenes is treated.

The 3D surface is approximated by a triangular mesh to reduce geometric complexity and to tailor the ...
