The teapots program presented below is extended version of the program demonstrating directional Blinna-Phong lighting described in book: "OpenGL podstawy programowania grafiki 3D" by Janusz Ganczarski. In comparison to its base the teapots program show how to load 3D objects from external data files and how to display several primitives and handle each of them in separation to each other.
Programmers interested in theory of Blinn-Phong light model (or other types of lighting) in modern OpenGL are encouraged to read book above. It is available in Helion.pl
