The design and display of 3D models on a computer
screen is usually interleaved
by a series of data manipulations. Data are usually
sets of 3D points that make up
polygonal patches in the composition of polyhedral
models. Manipulations are the
transformation operations that are applied to points
to facilitate design and visual understanding
of the graphical models. To further facilitate the
visual understanding of
the displayed models for applications such as the
field of anatomy, or speed up the
design phase for applications such as rapid
prototyping, methods are proposed to interactively
query data points for shape-control, segment portions
of displayed surfaces
for independent modification, modify and re-integrate
the modified segments to the
main structure, thereby limiting the number of
polygons that need to be manipulated
for computationally cheaper and faster results.
This book illustrates how polyhedral surfaces can be
organized into special data
structures to facilitate rapid selection of groups of
data points, and provides several
algorithms to facilitate the applications of
interactive operations on such selected data.
