User-Guided Inverse 3D Modeling
This page documents our research on the topic of User-Guided Inverse
3D Modeling, a powerful approach to shape re-design.
"Interactive Inverse 3D Modeling"is a user-guided approach to
shape construction and redesign that extracts well-structured,
parameterized, procedural descriptions from unstructured,
hierarchically flat input data, such as point clouds, boundary
representation meshes, or even multiple pictorial views of a
given inspirational prototype. This approach combines
traditional "forward" 3D modeling tools with a system of
user-guided extraction modules and optimization routines. With a
few cursor strokes users can express their preferences of the
type of modeling primitives to be used in a particular area of
the given prototype to be approximated, and they can also select
the degree of parameterization associated with each modeling
routine. The results are then pliable, structured descriptions
that are well suited to implement the particular design
modifications intended by the user.

Source for Inverse 3D Modeling. This is a public
re-implementation of our User-Guided Inverse 3D Modeling
Library (with Source) for Kinematic Surface Fitting. A
surface fitting library used to fit surfaces of revolution and
helical sweeps in our Inverse 3D Modeling system. This library
is an implementation of our "Generalized, Basis-Independent
Kinematic Surface Fitting" paper, and is more robust than
previous kinematic surface fitting methods.
Library (with Source) for Direct, Type-Specific Quadric
Surface Fitting. A surface fitting library used to fit
quadrics in our Inverse 3D Modeling system. This library is an
implementation of our "Type-Constrained Direct Fitting of
Quadric Surfaces," and includes improvements to the state of
the art in direct quadric fitting, as well as fitting methods
for an exhaustive set of quadric types: Ellipsoids, spheres,
hyperboloids of one or two sheets, general quadric cylinders
and cones, circular cylinders, circular cones, elliptical and
hyperbolic paraboloids, spheres, planes and more!
