Abstract. We propose a novel approach for the medial axis approxima-
tion of triangulated solids by using a polyhedral unit ball B instead of
the standard Euclidean unit ball. By this means we compute the exact
medial axis MA() of a triangulated solid with respect to a piecewise
linear (quasi-) metric dB. The obtained representation of by the me-
dial axis transform MAT() allows for a convenient computation of the
trimmed offset of with respect to dB. All calculations are performed
