    Hybrid Function Representation with Distance Properties
    (The Eurographics Association, 2019) Tereshin, Alexander; Adzhiev, Valery; Fryazinov, Oleg; Pasko, Alexander; Cignoni, Paolo and Miguel, Eder
    This paper describes a novel framework allowing for a hybrid representation of heterogeneous objects. We consider advantages and drawbacks of the conventional representations based on scalar fields of different kinds. The main result is introducing a hybrid representation called Hybrid Function Representation (HFRep) that preserves the advantages of the Function Representation (FRep) and Signed Distance Fields (SDFs) without their drawbacks. This new representation allows for obtaining a continuous smooth distance field in the Euclidean space for the FRep. We present the mathematical basics for our approach that uses the Discrete Distance Transform (DDT) and a step-function. The procedure for generation HFRep using continuous interpolation and smoothing techniques are also described. A few examples show how the approach works in practice.

    Traditional Romanian Egg Decoration in Augmented Reality with 3D Printing
    (The Eurographics Association, 2022) Ureche, Ana-Maria-Cristina; Fryazinov, Oleg; Anderson, Eike Falk; Ponchio, Federico; Pintus, Ruggero
    The folk art of decorating Easter eggs is an important part of Romania's intangible cultural heritage. We have developed a prototype for a mobile Augmented Reality (AR) app that allows users to virtually decorate Easter eggs, using a 3D printed egg as a physical AR marker to allow tangible interaction with the egg, mimicking the decorating process.
