Hi all I am new here and also to openGL. In lesson 6, we have a tutorial on how to load bmp files as texture. May I know how should I go about loading tiff files instead of bmp files? Thanks in advance. Cheers

You'll either have to find a lib that is able to load .tiff-images or write your own.

The one you're using in Lesson 06 (glaux) is only capably of dealing with .bmp afaik.

If you want to write your own take a look at wotsit. Otherwise take a look at SDL, I think it comes with an image library.

Edit: btw. for the sake of saving disk-space I'd recommend using .png. Loading a 10 kB compressed image and doing some decompression in memory might even be faster then loading the same image uncompressed with 100 kB, since the disk is considerably slower then cpu/memory.

Thanks. Actually I tried using the libtiff but had problems getting it work in Visual c++ because it is unable to locate a dlibtiff.lib file.

google for it and download it.

Tried that but still couldn't find it.
