The problem is that there is not just one activity that computer graphics are used for, there are a whole bunch spanning from things like "Piping design for industrial waste management" all the way to "movie special effects" ...

The details of exactly what technology, file formats, etc... is used are different between those various uses of computer graphics.

So it's difficult to have an "overall tutorial" on such a wide ranging field, you need to look for things that are focused more on a particular kind of activity that you are interested in.

Maybe something like this could be useful as a general overview though:
