ppm file format description
C function that reads ppm file, P6
sample ppm file, P6
Texture samples page
- RGBpixmap.h
  . You need readPPMFile and readBMPFile for reading image files.
- RGBpixmap.cpp
  - Note the C function for reading ppm file is incorporated in the classy
  - rgbpixmaps.cpp, implementation of the method RGBpixmap::setTexture which sets the parameters for a texture object (ideally should be inside RGBpixmap.cpp though)
  - textr2.cpp, example source mapping texture brick array to a square wall
    brk.bmp, sample brick texture image file (BMP)
    mazetexcolinter.cpp, exampleon texturing a rectangle and a columny
  - Be careful if you read .bmp files the color order is (blue, green, red), the .ppm is (red,green,blue).
- Message from a fellow student:
  
  Paint Shop Pro: 30 day trial - I haven't used this package since an earlier version but it was quite good. http://download.com.com/3000-2192-7057820.html?tag=lst-0-1
  
  If you have MS Office you should have the MS Office Photo Editor which is my choice (Load and Save TIFF/GIF/JPEG/BMP/PNG files)
