    Computer Graphics: An Interactive Introduction with OpenGL
    (The Eurographics Association, 17-9-2009) Hunkins, Dalton; -
    Computer Graphics: An Interactive Introduction with OpenGL is a suite of examples and interactive tutorials. The software is created for the person who wants an introduction to computer graphics using the OpenGL API. It is assumed that the reader is familiar with programming in the C++ language; knowledge of OpenGL is not a pre-requisite. Also, the tutorials and examples may be used in conjunction with many of the mainstream books on computer graphics.

    GLRex
    (The Eurographics Association, 10-8-2006) McDonald, Gerard; -
    I first taught computer graphics programming on PCs in the late 1980s. We produced images with a few platonic solids in 256 colors. Real-time animation was out of the question. I remember writing programs for my classes to do ray-tracing and hidden surface removal that ran at glacial speed. Despite all the shortcomings, the students enjoyed the classes and the images they could create, even though they were relatively simple. Computer graphics was still something of a novelty, and producing any image for the computer to display was exciting. By the mid-1990s things had changed quite a bit. High-end graphics libraries like OpenGL had become available for the PC. Combining them with improvements in hardware (more memory, faster processors, better video cards), it was now possible to do relatively sophisticated graphics even on low-end PCs. At the same time students' expectations were rising as computer graphics became more pervasive in our culture. They are accustomed to seeing very sophisticated computer imagery in the games they play and the movies they watch. Students expect to be able to create visually exciting projects. But beginning students often find their creativity limited by the tedium of building scenes directly in code. GLRex is an attempt to address this problem. GLRex is a simple modeler that provides the user with interactive assistance in creating code for complex images. The user can create scenes with spheres, boxes, cylinders, and cones, as well as NURB surfaces of revolution and extrusion. These scenes may then be exported as OpenGL-based C programs (or RenderMan RIB files) to be used as a basis for more complex projects.

    Realtime 3D Graphics Programming Using the Quake3 Engine
    (The Eurographics Association, 18-7-2008) Wagner, Daniel; Schmalstieg, Dieter; Kainz, Bernhard; -
    We present a lab assignment that accompanies a complete module called ''Real-time Graphics''. The students' task is to get familiar with content creation and programming a (previously) commercial 3D engine. In a first task, students have to create 3D content, which is integrated into the Quake3 engine. In a second task, the students have to implement a simple animation and finally add an impressive 3D graphics effect to the Quake3 engine. The lecture has been taught four times from 2004 to 2007. We present the assignment and report on experiences that we have gained.

    A Self-Training Tool for Learning 3D Geometrical Transformations
    (The Eurographics Association, 17-9-2009) Ribelles, Jose; Lopez, Angeles; -
    This paper presents a self-training tool for learning 3D geometric transformations, i.e. translation, scaling and rotation. Our aim is to provide students with a tool they can use to practise these transformations by themselves so that they can understand and learn how to use them. Its main feature is to show an animation of the geometrical transformation applied on a geometric primitive. This animation helps to comprehend the transformation more easily, as the student sees how the primitive changes its size, position and orientation. Furthermore, the teacher can also use it as a teaching aid to explain and solve exercises in class. The geometric primitives as well as the transformation parameters used in this tool are those provided by the GLUT library and the OpenGL standard. Moreover, one of the results the tool can also provide is the C source code of the scene for OpenGL programming, which is very useful if the student needs to learn to program OpenGL transformations. Finally, this tool has been made available to our students for three academic years, and they found it very useful.

    ShaderSchool – A tutorial for shader programming
    (The Eurographics Association, 9-7-2007) Reimers, Ulf; Beckhaus, Steffi; Thiesen, Malte; -
    We present a tool for in-class and self-study learning that provides a convenient introduction into GLSL shader programming. The tool presents shaders in an interactive manner, and can be present in-class in a group interactive manner or used as an individual tutorial. In ShaderSchool the materials are presented in sections with interactive assignments integrated into the tool, which help reinforce the students learning. It was created and applied successfully in an university computer graphics class. Additionally, the ShaderSchool tool is extensible to easily incorporate further lessons. 1 Introduction

    ShadowGui – An Interactive Shadow Tutorial
    (The Eurographics Association, 8-10-2007) Kuehl, Bjoern; Blom, Kristopher J.; Beckhaus, Steffi; -
    Today's mainstream computer graphics converges more and more to what was, in the past, possible only to do with expensive workstations. The addition of shaders to consumer graphic boards, which enable the usage of special effects like bump mapping and per pixel lighting, changed the look of today's computer graphics totally. One main effect, which makes the scene look more realistic, is shadows. It can help the viewer to understand the relative position of objects making the scene more believable. There are several common methods of making shadows, each of them having advantages and disadvantages. The two most popular methods are shadow mapping and stencil shadow volumes. In this tutorial, both shadow methods are explained two times. The first time, using only pure cpu-power, which makes the approaches slow, but they are easier to understand. Then, the tutorial explains how to use the power of today's graphic cards by outsourcing calculations to shaders. Because the shadow generation methods are implemented using OpenGL, previous knowledge about this graphics library is recommended, for example how to move objects by manipulating the glModelView matrix. However, all that must be known to calculate shadows will be explained in this tutorial.

    Teaching CGI Through Real Hands-On Experience
    (The Eurographics Association, 18-7-2008) Bernar, Carlos; Torrents, Joaquin; -
    Euroview Animation is developing a methodology for teaching CGI within the Department of Film, TV & Digital Media at the University of Navarra involving the participation of the students in actual production process. We base our educational methodology on the real hands-on experience: our students learn through their participation in the production of a real feature film. The production process of the film inspires and determines the learning process of our students. We consider that our project can be valuable for other educators in CGI because (1) our method has real consequences: our first feature film, Flying Heroes, will be in theaters in 2008, (2) as far as we know, this is the first of-its-kind experience with these requirements in a university and in the industry (3) this kind of project offers many possibilities of collaboration between universities.

    X3D: Extensible 3D Graphics for Web Authors
    (The Eurographics Association, 2-8-2008) Brutzman, Don; -
    X3D is the ISO-standard scene-graph language for interactive 3D graphics on the Web. A new course is available for teaching the fundamentals of 3D graphics using Extensible 3D (X3D). Resources include a detailed textbook, an authoring tool, hundreds of example scenes, and detailed slidesets covering each chapter. The published book is commercially available, while all other course-module resources are provided online free under an open-source license. Numerous other commercial and open resources are available for X3D, which also serves as an interchange format. The supported course has been taught for many years, successfully introducing masters' students to the principles and techniques of 3D graphics without requiring programming experience. This course and module appears to be ready for undergraduate use. Expressing 3D within the domain of Extensible Markup Language (XML) for the Web is novel and has the potential to open up computer graphics to many new practitioners. This combined resource is intended broadly support computer graphics education and skills for web authors.
