Virtual Texture Mapping 101
Matthäus G. Chajdas, Christian Eisenacher, Marc Stamminger, Sylvain Lefèbvre · 2010
From the literature, we may extract two different approaches: object-space and image-space algorithms. However, most modern algorithms work in either image space or hybrid space. For the purposes of this chapter, we are interested in GPU-based algorithms, and these are the ones we will present. We refer the interested reader to the works of [Isenberg et al. 03] and [Hartner et al. 03] for overviews and deep comparisons on CPU-based silhouette extraction algorithms.
