Geometric approximation of the sphere by triangular polynomial spline patchesVavpetič, Aleš ; Žagar, Emil, 1969-Sfera je osnovni geometrijski objekt, ki se pogosto uporablja v (računalniško podprtem) geometrijskem oblikovanju. Ima racionalno, nima pa polinomske parametrizacije. Pričujoča študija podaja pristop ... k optimalni aproksimaciji enakostraničnih sferičnih trikotnikov s parametričnimi polinomskimi krpami, če je mera kvalitete aproksimacije radialna napaka. Posledično je podana optimalna aproksimacija enotske sfere z zlepki parametričnih krp nad določeno triangulacijo sfere, ki jo porodijo včrtani tetraeder, oktaeder in ikozaeder. Podrobno so analizirani neketeri zlepki nizke totalne stopnje z ustrezno geometrijsko gladkostjo. Numerični primeri potrjujejo kvaliteto aproksimacije.Source: Computer Aided Geometric Design. - ISSN 0167-8396 (Vol. 92, Jan. 2022, art. 102061 (12 str.))Type of material - article, component part ; adult, seriousPublish date - 2022Language - englishCOBISS.SI-ID - 88497155
