TextureBMP

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.

• FourTexturesProject.zip: A zip file, including the source files, Microsoft Visual C++ workspace and project files, Win32 executable, and a bitmap file..
• FourTextures.zip: A zip file, with sources files, the executable, and the ffour bitmap files.
• TextureBMP.cpp and RgbImage.cpp and RgbImage.h and TextureBMP.exe and IvyTexture.bmp and WoodGrain.bmp   and LightningTexture.bmp and RedLeavesTexture.bmp:  Download the three source files, the executable, and the four texture maps one at a time.

Things to look at:

1. Compile and run the program.  Note how it behaves when the window is resized larger and smaller.  Do you see an unwanted aliasing problems?
2. Examine the code and figure out how to use OpenGL to manage multiple textures.
