We propose a new texture sampling approach that preserves crisp
silhouette edges when magnifying during close-up viewing, and benefits
from image pre-filtering when minifying for viewing at farther
During a pre-processing step, we extract curved silhouette edges from
the underlying images. These edges are used to adjust the texture
coordinates of the requested samples during magnification. The
original image is then sampled -- only once! -- with the modified
The new technique provides a resolution-independent image representation
capable of billions of texels per second on a mid-range graphics card.
