Abstract

Given a compact subset F of R², the visible part V_θF of F from direction θ is
the set of x in F such that the half-line from x in direction θ intersects F only at
x. It is suggested that if dim_H F ≥ 1 then dim_H V_θF = 1 for almost all θ , where
dim_H denotes Hausdorff dimension. We conrm this when F is a self-similar set
satisfying the convex open set condition and such that the orthogonal projection
of F onto every line is an interval. In particular the underlying similarities may
involve arbitrary rotations and F need not be connected.
