abstract = {Transparency can be a useful device for simultaneously depicting
multiple superimposed layers of information in a single image.
However, in computer-generated pictures - as in photographs and in
directly viewed actual objects - it can often be difficult to
adequately perceive the three-dimensional shape of a layered
transparent surface or its relative depth distance from underlying
structures. Inspired by artists’ use of line to show shape, we
have explored methods for automatically defining a distributed set
of opaque surface markings that intend to portray the
three-dimensional shape and relative depth of a smoothly curving
layered transparent surface in an intuitively meaningful (and
minimally occluding) way. This paper describes the perceptual
motivation, artistic inspiration and practical implementation of
an algorithm for "texturing" a transparent surface with uniformly
distributed opaque short strokes, locally oriented in the
direction of greatest normal curvature, and of length proportional
to the magnitude of the surface curvature in the stroke direction.
The driving application for this work is the visualization of
layered surfaces in radiation therapy treatment planning data, and
the technique is illustrated on transparent isointensity surfaces
of radiation dose.},
