Na področju prostorske informatike obstaja potreba po pregledu in urejanju trodimenzionalnih geometrijskih podatkov. Položaji teh geometrijskih podatkov morajo v večini primerov temeljiti na podatkih v drugih oblikah (npr. položajih točk v oblaku točk). V okviru te diplomske naloge smo razvili JavaScript knjižnico, ki omogoča prikazovanje oblakov točk, 3D modelov v formatu IFC in trodimenzionalnih geometrij, ki ustrezajo podatkovnemu formatu GeoJSON. Razvili smo tudi orodja, ki uporabnikom omogočajo risanje in urejanje geometrij na prikazanih podatkih ter premikanje po 3D prostoru. Ta orodja se prilagajajo oblakom točk in geometriji poljubnih 3D modelov. Poudarek pri razvoju knjižnice je bilo doseči čim boljšo uporabniško izkušnjo med uporabo orodij in razvijalcem ponuditi knjižnico, ki ni odvisna od zunanjih storitev in spodbuja pisanje pregledne in razumljive kode. Za knjižnico smo razvili tudi spletni uporabniški vmesnik, ki omogoča demonstracijo njene funkcionalnosti in izvedli analizo uporabniške izkušnje.

• Title: Development of a web tool for drawing three-dimensional geometries on point clouds and 3D models

Abstract

In the field of spatial informatics, there is a need to view and edit three-dimensional geometric data. In most cases, the position of this geometric data must be based on data in other formats (e.g., the position of points in a point cloud). As part of this thesis, we developed a JavaScript library that enables the display of point clouds, 3D models in the IFC data format, and three-dimensional geometries that comply with the GeoJSON data format. We also developed tools that allow users to draw and edit geometries on the displayed data and navigate the 3D scene. These tools adapt to point clouds and the geometry of any 3D model. The main focus during the development of the library was to achieve the best possible user experience while using the tools and to offer developers a library that does not depend on external services and promotes writing transparent and understandable code. Additionally, we developed a web user interface for the library to demonstrate its functionality and conducted a user experience analysis.
