AB  - We are facing a number of applications for altering portrait photographs using the help of artificial intelligence. Apart from the entertainment purposes, modern computer technologies can also help us get dynamic effects from static images, an example of which is the subject of this study. Dealing with the change of lighting in portraits photographs through real-time rendering, this paper provides a method of obtaining an image with variable light source that affects the facial features generated on the basis of the face tracking data acquired from the existing static photograph. Thus, we get a portrait with altered light, as if such a source was present at the actual moment of photographing. This method aims to improve or even change the visual experience when viewing the image, so that its further application corresponds to the given context.

AB  - The idea for this design came from investigation of forms created as “time imprint” of moving 2D and 3D objects through space, while simultaneously changing their transformations: translation, rotation, scaling, etc. The movement develops along a path that can be either assigned or random. In this manner, the movement, only possible with the time component, remains “frozen” in the form of a solid model. Hence, we may assume time as a modelling tool, which connects and unites successive movements of an object into a whole.
The procedure in question is visualized with Blender 3D animation and modeling tools. The render examples visualise time based extrusion of the object’s random transformations in 3D space. The transformations are randomly generated and controlled by noise function. 
In order to examine the possibilities of such a creating of spatial forms for more interesting results, we start from a 2D figure (snow flake), via elementary 3D figure (cube), and then examine how the form is enriched by introducing more complex figures as generatrices, for example concave polyhedron (CbP II-8), or a group of objects. For the procedure itself, we adopt a path which can be the simplest one (straight line, circle), or more complex (with curves, angles or nodes).

For the procedure itself, we adopt a path which can be the simplest one (straight line, circle), or more complex (with curves, angles or nodes). We also explore what kind of "time imprint" in space leaves the chosen starting figure in a free movement, i.e. for a non-geometric path, but also randomly generated one. The given modelling method provides simple and quick, but very intriguing options for creating a wide range of shapes that can be used in various areas of art and design: from graphic design, to a novel way of sculptural and even architectural design. These forms may convincingly represent natural and bionic forms, e.g. hair strands, vegetation growth, etc. The possibility of 3D printing enables the physical materialization of these shapes, suitable for further processing and use for decorative purposes, such as architectural ornaments or jewellery. As an integral part of the research, we include animation which shows the method of generating shapes in the described manner
