Interactive non-photorealistic rendering

Due to increasing demands of artistic style with Interactive Rate, we propose this review paper as a starting point for any person interested in researching of interactive non-photorealistic rendering. As a simple yet effective means of visual communication, interactive non-photorealistic rendering generates images that are closer to human-drawn than are created by traditional computer graphics techniques with more expressing meaningful visual information. This paper presents taxonomy of interactive non-photorealistic rendering techniques which developed over the past two decades, structured according to the design characteristics and behavior of each technique. Also, it covers the most important algorithms in interactive stylized shade and line drawing, and separately discussing their advantages and disadvantages. The review then concludes with a discussion of the main issues and technical challenges for Interactive Non-Photorealistic Rendering techniques. In addition, this paper discusses the effect of modified phong shading model in order to create toon shading appearance

A General Framework for Digital Game-Based Training Systems

This dissertation introduces a general framework for developing digital game-based training systems. The framework addresses all aspects of education. In that sense, it involves both teacher and student as game players. A visual review log supports teacher-student-communication. Based on the general framework, a novel digital game-based training system for crime scene investigation training called OpenCrimeScene has been developed and implemented.Diese Dissertation führt ein allgemeines Architekturmodell für die Entwicklung von computerspielbasierten Trainingssystemen ein. Das Architekturmodell spricht alle Aspekte der Ausbildung an. In diesem Sinne bezieht es Lehrer und Schüler als Spieler ein. Ein grafisches Bewertungsprotokoll unterstützt die Lehrer-Schüler-Kommunikation. Basierend auf dem allgemeinen Architekturmodell wurde ein neues computerspielbasiertes Trainingssystem zur Tatortsicherung entwickelt und implementiert
