I guess the raw files are not getting read. hey can u pls help me out , i m not able to see the output of this code , I m using codeblocks to run this code and i have placed the texture file in bin directory of the project.

I had a question about the texture memory thing above because in my project I am using a sprite sheet method. Is there anyway to check how large of a texture a card will support in my code and then maybe use an alternate method? I know it would be easier to just do either or, but I was just wondering. Thanks! Hello Swiftless,

In this example, I have them in a folder called "textures" which is in the same directory as the application. Cheers, Swiftless Hi Pankaj,

The problem with doing this in a larger game is that if you have a large file you will run out of texture memory extremely quickly. A lot of graphics cards don't support textures with a size greater than 2048x2048. Also, if you look at files such as movie files, or gifs, then you have no choice usually but to load it in frame by frame as that is how the file format is stored. Cheers, Swiftless Hi Limanima,

Why not use a single texture file and then change the texture uv coordinates of each vertex? Usually an animated image goes to a cardboard which has only 4 vertexes. There won't be much impact of changing those coords on the fly. Better then having 100s of images on disk... Hum..
