what's the total number of "i"s in:
modern game engines are a complex combination of multiple technologies. this unit will extend your knowledge of game programming by providing you with theory and practice in using advanced engine technology elements such as geometry manipulation and real time rendering techniques. game engines simulate physics to provide a basis for the development of game worlds. this unit will give you a thorough understanding of the mathematics behind these visual simulation components and the ability to solve problems in related game engine development. the unit is placed later in the course to provide you with advanced knowledge and skills for programming 3d game engines, in conjunction with igb383 ai for games. the theory and skills learned in this unit will help you create a high quality game in your capstone project units igb300 and igb301.
