FourTextures
FourTextures is sample C++ code illustrating the use of multiple textures in OpenGL. It is intended to accompany the book 3D Computer Graphics: A mathematical approach with OpenGL, by S. Buss, Cambridge University Press, 2003. However, it can be used independently as well.
FourTextures reads four texture map from a bitmap file (.bmp extension). The main program is in TextureMap.cpp. The C++ class RgbImage is used to read the images' data from a bitmap files.
There are several options for downloading the files.
