Implicitization of Rational Parametric Surfaces
Journal of Symbolic Computation, 1996 Let \(S\subset \mathbb{C}^3\) be a surface parametrized by a map \(F_a(s,t)= (f_1(s,t),\;f_2(s,t),\;f_3(s,t))\), where \(f_i\) are polynomials in \(s\) and \(t\). The implicitization process would find an equation \(f(x,y,z)=0\) such that the zero locus of the equation, \(W=\{(x,y, z)\mid f(x,y,z) =0\}\), is the smallest subset \(W\subset \mathbb{C}^3\)

Velocity calculation of 2D geometric objects by use of surface interpolation in 3D
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014 In some engineering applications, it is desirable to calculate the local velocity of geometric objects or boundaries of physical phenomena to understand the deformation speed of the objects or the mechanisms of the physical phenomena.

Modelling with implicit surfaces that interpolate [PDF]
ACM Transactions on Graphics, 2002 We introduce new techniques for modelling withinterpolating implicit surfaces. This form of implicit surface was first used for problems of surface reconstruction and shape transformation, but the emphasis of our work is on model creation. These implicit surfaces are described by specifying locations in 3D through which the surface should pass, and ...

Control Modification of Grasp Force Covaries Agency and Performance on Rigid and Compliant Surfaces
Frontiers in Bioengineering and Biotechnology, 2021 This study investigated how modifications in the display of a computer trace under user control of grasp forces can co-modulate agency (perception of control) and performance of grasp on rigid and compliant surfaces.
