Silhouette masking?

[Matt B]

A while ago i remember stumbling across an article on a technique for generating the silhouette of a low poly object from a high poly reference image. In combination with normal mapping a low poly object looked virtually inseperable for the high poly one. Does anyone still have the link to it? Also what are the performance implications of this technique?

Is this what you are looking for?

An apparent limit of silhouette mapping (or any image based approach) is the difficulties of transformation (i.e. it's not easy to change the shape of an object).
