1. Pristop k vizualizaciji podatkov na osebnem računalnikuDavid Podgorelec, Marko Vinter, Borut Žalik, 2002, original scientific article Abstract: V članku je predstavljen algoritem za senčenje prostorskih podatkov, ki je zaradi svoje enostavnosti in hitrosti primeren tudi za uporabo na osebnem računalniku. Množice podatkov, ki jih je zmožen vizualizirati, so dovolj velike za učinkovito rabo v medicinskih aplikacijah. Algoritem temelji na sekundarnem geometrijskem modelu, ki smo ga poimenovali seznam vidnih vokslov. Vizualizacijo poskuša pospešiti s predhodnim izločanjem vokslov, nezanimivih za uporabnika. Ti tako imenovani beli voksli predstavljajo zrak, notranjost objektov in dele površja objektov, ki niso vidni iz trenutnega položaja opazovalca. Delovanje in učinkovitost algoritma smo predstavili na nekaj praktičnih primerih uporabe pri vizualizaciji medicinskih podatkov.

2. Employing visualisation techniques and tools for educational purposes in textile studiesZoran Stjepanović, Darinka Fakin, 2010, original scientific article Abstract: Modern textile and clothing manufacturers can today use the entire range of conventional CAD/CAM systems together with new computer graphics and Internet-based technologies in order to strengthen their position on the market, building a completely new electronic-business offer. Graphical presentation of textile products and processing, or visualisation, presents a promising technology that can be treated as a potential enrichment of conventional computer aided technologies used today by the majority of advanced producers of textile fabrics, clothing, and other textile products. The article presents the results of research on designing computer software for visualising the fabric dyeing process. The program package produced enables the effective visualisation of two fabric dyeing processes: a Pad-Batch machine line for dyeing flat textiles in open-width state, and an HT overflow dyeing machine for fabric dyeing in rope form. Graphical applications of both dyeing processes can be used for both industrial and educational purposes. In this article, we focus more on presenting the program structure and functionalities for using the software to support the education of textile students.

3. Influence of blending functions on volumetric cloud imagesBogdan Lipuš, Nikola Guid, 2008, original scientific article Abstract: Various blending functions can be applied in the volumetric modelling of clouds. This paper analyzes the impact of five different blending functions (linear, cubic, Wyvill-1, Wyvill-2, and cosine) on cloud shape, structure, and area. We have found that there are only negligible differences among them. Therefore, we can conclude that the simple linear blending function satisfies all the desired properties for generating cloud images by volumetric modelling.
