Triangulation of 3D Surfaces: From Parametric to STL Surfaces

Result description

The paper deals with generation of computational meshes over 3D surfaces described discretely by a stereolithography (STL) file. Initially, a boundary representation of the underlying model is constructed. Then smooth curves and surfaces forming this model are recovered from the STL mesh using recursive subdivision. Finally, computational mesh is generated over the recovered smooth surfaces using the advancing front technique.

    Triangulace 3D ploch: Od parametrických k STL plochám

  • Czech description

    Clánek se zabývá generováním výpočetních sítí na 3D plochách popsaných diskrétně pomocí stereolitografického (STL) formátu. Na počátku se zkonstruuje hraniční reprezentace daného modelu, ze které se po té s použitím rekurzivního dělení obnoví hladká reprezentace jednotlivých ploch, jež se nakonec podrobí discretizaci metodou postupující fronty.
