Abstract

V magistrski nalogi je predstavljena uporaba parametričnega modeliranja za izdelavo modela smučarske skakalnice. Uporaba takšne vrste projektiranja bi namreč lahko, predvsem v začetnih fazah, bistveno pospešila projektiranje smučarskih skakalnic, katerih posebna geometrija lahko zahteva precej dodatnega časa pri modeliranju modela na običajen način. Izdelan geometrijski model pa se lahko uporablja za dokumentacijo, vizualizacijo, analize količin in napredne simulacije. Parametrično modeliranje omogoča, da z uporabo drsnikov ali numeričnega vpisa ključnih parametrov skakalnice, na primer za krivulji zaletišča in doskočišča, avtomatično zgeneriramo primerke celotnih geometrij variant skakalnic, podrobneje pa lahko parametriziramo tudi druge dele skakalnic. Prvi del naloge podaja teoretične osnove projektiranja skakalnic in parametričnega modeliranja. Ta del zajema pregled strokovne literature, ki se nanaša na omenjeni temi, opis programskih orodji, uporabljenih v drugi polovici tega dela, in pa povzetek standarda, ki podaja priporočila za načrtovanje smučarskih skakalnic. Drugi del naloge demonstrira izdelavo parametričnega modela s programskim orodjem Grasshopper in možnost povezave z informacijskim modelirnikom ArchiCAD. Temu sledi primerjava karakteristik znanih smučarskih skakalnic z določili iz standarda, na primeru skakalnic, ki se tem vrednostim najbolj približata pa je uporabljen izdelan parametrični model. V sklepnem delu so zapisane ugotovitve, do katerih sem prišla tekom izdelave zaključnega dela ter prednosti in slabosti, ki jih parametrizacija prinaša za primer načrtovanja skakalnic.

Secondary title:	Parametric model of the inrun and outrun of a ski jumping hill
Secondary abstract:	This masters thesis shows the possibility of using a parametric model for the design of a ski jumping hill. Using this kind of design, especially in early stages of a project, could speed up the designing process significantly, mainly because of the complex geometry of a ski jumping hill. Parametric modelling allows us to generate the whole geometry of different ski jumps, using number sliders or numerical input to define the key parameters of a ski jumping hill. With the same principle, we can also parametrize other parts of a ski jump, such as safety rails, load bearing elements and starting platforms. First half of the thesis shows the theoretical basis of designing a jumping hill and of parametric modelling. This part contains the overview of available literature, which describes both topics, description of used software and a summary of the standard for designing ski jumping hills. The second half of the thesis describes making of the model with parametric modelling tool called Grasshopper and shows the possibility of connecting Grasshopper to ArchiCAD, a building information modelling software. This is followed by a comparison of famous jumping hills, characteristics to values as described in standard. The two jumping hills, that follow the standard the most, are then modelled with the newly made parametric generator. The ending of the thesis shows the conclusions that were made during its writing and the advantages and disadvantages of using parametric tools when designing a ski jumping hill.
