    • Locally Refinable Splines over Box-Partitions 

      Dokken, Tor; Lyche, Tom Johan; Pettersen, Kjell Fredrik (SINTEF Rapport;, Research report, 2012)
      We address progressive local refinement of splines defined on axes parallel box-partitions and corresponding box-meshes in any space dimension. The refinement is specified by a sequence of mesh-rectangles (axes parallel ...

    • Stable Simplex Spline Bases for C3 Quintics on the Powell–Sabin 12-Split 

      Lyche, Tom Johan; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2016)
      For the space of \(C^3\) quintics on the Powell–Sabin 12-split of a triangle, we determine explicitly the six symmetric simplex spline bases that reduce to a B-spline basis on each edge and have a positive partition of ...
