Developing Graphics Frameworks with Java and OpenGL

Developing Graphics Frameworks with Java and OpenGL shows you how to create software for rendering complete three-dimensional (3D) scenes. The book explains the foundational theoretical concepts as well as the practical programming techniques that will enable you to create your own animated and interactive computer-generated worlds. You will learn how to combine the power of OpenGL, the most widely adopted cross-platform application programming interface (API) for graphics processing unit (GPU) programming, with the accessibility and versatility of the Java programming language. Topics in this book include generating geometric shapes, transforming objects with matrices, applying image-based textures to surfaces, and lighting a scene. Advanced sections explain how to implement procedurally generated textures, postprocessing effects, and shadow mapping. In addition to the sophisticated graphics framework discussed throughout the book, you will gain a foundational knowledge that will allow you to adapt and extend that framework, leading to even more spectacular graphical results.
