Silhouette Maps for Improved Texture Magnification

Let's take a look at another example. Here is a street sign that was converted into a 128x128 pixel texture.

On the left we have the result of standard bilinear interpolation - we can see it looks blurry.

On the right we have the result of our silhouette map textures, and we can see how texture appears much sharper.
