Approximate Implicitization of Triangular Bézier Surfaces
Oliver J. D. Barrowclough, Tor Dokken
We discuss how Dokken's methods of approximate implicitization can be applied to triangular Bézier surfaces in both the original and weak forms. The matrices and $\mat…
Fast Approximate Implicitization of Envelope Curves using Chebyshev Polynomials
Oliver J D Barrowclough, Bert Jüttler, Tino Schulz
Consider a rational family of planar rational curves in a certain region of interest. We are interested in finding an approximation to the implicit representation of the envelope.…
Direct interactive visualization of locally refined spline volumes for scalar and vector fields
Franz G. Fuchs, Oliver J. D. Barrowclough, Jon M. Hjelmervik +1
We present a novel approach enabling interactive visualization of volumetric Locally Refined B-splines (LR-splines). To this end we propose a highly efficient algorithm for direct…
