Procedural Generation of Terrain within Highly Customizable JavaScript Graphics Utilities for WebGL

摘要

Modelling realistic scenes and rendering them appropriately are two key aspects of modern computer games. Scenes need to be detailed, realistically non-repetitive and computationally feasible. Procedural generation involves encoding a game scene as a recipe or procedure that can be generated and regenerated at run time, rather than just loaded from file or network server. Procedural generation in the context of web games and systems is particularly powerful in reducing bandwidth transfer requirements. We describe experiments to implement a framework for procedural generation using JavaScript and modern web client software systems such as WebGL and OpenGL shader language. Our system is able to exploit available Graphical Processing Units (GPU) and is aimed at supporting existing web based graphics engines. We present some graphical results and discuss future performance and scalability issues.
