Silhouette Maps for Improved Texture Magnification

Using only these points, however, the renderer does not have enough information to decide the location of the original discontinuities. You see here three examples of the many different discontinuities that would have yielded the silhouette points shown. None of them match the discontinuities of our original texture.

The problem is that the current silhouette map structure stores only the position of the potential discontinuities, but does not indicate which of them are actual discontinuities or not.
