abstract = {We present real-time vascular visualization methods, which extend
on illustrative rendering techniques to particularly accentuate
spatial depth and to improve the perceptive separation of
important vascular properties such as branching level and supply
area. The resulting visualization can and has already been used
for direct projection on a patient's organ in the operation
theater where the varying absorption and reflection
characteristics of the surface limit the use of color. The
important contributions of our work are a GPU-based hatching
algorithm for complex tubular structures that emphasizes shape and
depth as well as GPU-accelerated shadow-like depth indicators,
which enable reliable comparisons of depth distances in a static
monoscopic 3D visualization. In addition, we verify the
expressiveness of our illustration methods in a large,
quantitative study with 160 subjects.},
