Abstract

This work is a study of problems related to the 3D visualization in the field of natural science. The introductory part briefly presents the tasks to be achieved, the technology used and how the problems have been tackled with. The following chapters describe each of the subjects in more detail. The first chapter introduces the notion of computer simulations, describes the possibilities for their use in different areas and mentions some of their disadvantages which we should be aware of. Particular attention is focused on the employability of simulations in the didactic process. The next chapter is dedicated to 3D rendering. It starts with an introduction to its meaning but most of the chapter is dedicated to a detailed mathematical argumentation of all the procedures which lead from the mathematical model to the final rendering on the screen. The chapter ends with a review of hardware accelerated 3D graphics, its development through time and possibilities of its use in Java environment. The main part of the work starts with the third chapter which introduces in detail the software product World 3D which accompanies this work. All of the program functions are described and the procedures which led to their realization are explained. In the next chapter the same program is described from the user point of view. Apart from the review of the programming interface for development of new nature science related tutorials, the chapter also includes a short description of enclosed examples and some starting tips for easier program use. In the appendix there is a short tutorial to the Java 3D graphics API Java 3D which used for all the rendering in the described software product. It starts with an explanation of the basic program framework in Java 3D and continues with a description of all main objects available to the programmer. In the end some more advanced programming techniques for this programming interface are pointed out.
