abstract = "We illustrate the suitability of Conformal Geometric Algebra for
representing deformable mesh models. State-of-the-art modeling
tools allow the user to deform 3D models (or region of interest)
by selecting sets of points on the surface, called handles, and
move them freely. The deformed surface should look {"}naturally{"}
stretched and bent. Mesh representations based on Conformal
Geometric Algebra extend, quite naturally, the existing deformable
mesh representations by introducing rigid-body-motion handles,
a.k.a motor handles, instead of just translation handles. We show
how these mesh representations conduct to a fast and easy
formulation for the Spline-aligned deformation and a formulation
for linear surface deformation based on generalized barycentric
coordinates. Also, we reformulate the Free-Form Deformation (FFD),
Harmonic Coordinates (HC) and As-Rigid-As-Possible (ARAP) Surface
Modeling into the Conformal Geometric Algebra framework and
discuss the advantages of these reformulations.",
