Bas-relief, Gradient operation, Unsharp masking, Poisson equation
Bas-relief is a type of sculpture artwork which is carved
into a plane or a surface, traditionally created by hand.
Recently, computers have been adopted to assist the
design and production of relief works. In this paper, we
propose a novel method to generate the 3D mesh of a
relief based on a 2D image input. Gradient operations,
such as magnitude attenuation and unsharp masking, are
introduced to convert an image into a relief. The Poisson
equation is solved for the construction of the depth
information of a relief from the tuned data. The final
output as geometric mesh enables artists or designers to
add additional texture and material features for their relief
design. More importantly, such a mesh can be directly
used for computer aided manufacturing as input.
