The thesis deals with design and implementation of the editor object-oriented Petri nets described by language PNTalk. A PNTalk compatible representation and storage format based on XML technologies will be created. The design of the individual parts of the editor focuses on the internal storage facilities, on the graphical user interface and its functionality. In the final part there are practical demonstrations of the application.

This document describes implementation of photo slideshow editor. This editor can be used to create dynamic sequences from taken photos. Image taken by camera is projected onto three-dimensional sphere and drawn to screen. Then it is posible to rotate and zoom camera over image. Visual output of this editor makes moving over image more real. If panoramic image is used, user is able to free look around. This document describes method which can translate two-dimensional coordinates to three-dimensional space. Shows how to use transformations for moving camera and methods to implement camera zoom. Contains description of user interface and also mentions extensions that were implemented in editor.

Main goal of this master´s thesis is to propose and implement improvements to an original purely raster version of Flame Painter editor. An enhancement of the undo/redo system with emphasise to its functionality and memory requirements has been implemented. Moreover, the editor was extended by adding an ability to edit brush strokes using vector primitives which effectively assist the user in future stroke editing. This project was created in cooperation with employees of the Escape Motions Company.

<p></p><p>Shader programming is an efficient way to render graphics yet can be complex to understand for emerging computational artists who are new to the world of creative programming. Since shaders are an important part of visual programming, making them easier to use should be considered an important factor in teaching basic to advanced concepts in the rendering pipeline of computer graphics. Though some tools like shader editors and interactive graphical interfaces have been designed to aid in the understanding of these concepts, they still fall behind in some areas in meeting the requirements of emerging computational artists. </p> <p>In this thesis we present and explore the usability of a new Shader Mode tool developed for an open-source software called Processing, widely used in education and production for digital arts and design, and discuss how it can aid shader programming for emerging computational artists. This tool was inspired by a project the author did for Google Summer of Code in 2018. The tool was tested with Processing users who have some familiarity with shader programming. The analysis of the tool was done using a mixed method research technique: combination of quantitative and qualitative analysis. Since we were unable to get enough users for the study, the results could not be generalized to all Processing shader users. However, relevant user feedback is discussed. </p><br><p></p>

Die Diplomarbeit entstand im Kontext der Projekte HematoWork bzw. AgentWork. Inhalt dieser Projekte ist die computerbasierte Unterstützung von medizinischen Arbeitsabläufen. Dazu wird ein Workflow-Management-System erstellt, welches insbesondere solche Arbeitsabläufe unterstützt, die dynamisch zur Laufzeit an sich ändernde Umgebungsbedingungen angepasst werden müssen. Der im Rahmen der Arbeit konzeptionierte und prototypisch implementierte Workflow-Editor ist eine Komponente des Workflow-Systems. Er ermöglicht die Erstellung von Arbeitsablaufplänen (Workflow-Definitionen) mittels einer grafischen Oberfäche. Wesentliche Inhalte der Arbeit sind dabei unter anderem die Vorstellung eines Workflow-Modells, welches speziell dynamische Änderungen zur Laufzeit ermöglicht, und ein Verifikationsalgorithmus, der die Korrektheit erstellter Workflow-Definitionen prüft.

Die vorliegende Arbeit beschreibt die Spezifikation einer Benutzeroberflaeche fuer den graphischen Editor GEX unter Unix unter Verwendung von OSF/Motif1.2.

Workshop "Netz- und Service-Infrastrukturen" Für viele Netzwerker ist die Arbeit nach der Definition eines XML-Dialakts erledigt. Die Praxis zeigt aber, dass das zur Verfügungstellen eines WYSIWYG-Editors unerlässlich ist.
