Hello. I want to find a computer language for doing real-time interactive graphics. I want to be able to operate on each point of an image in real-time. For example I thought it would be interesting to be able to write a program that will perform a Fourier Transform on an image, do some operation on it, and then transform it back, sort of like an optical filter. I’m not asking anyone to write me code that does this. It’s just an example of something I’m thinking of doing. What would be the best language for this task? I know ‘C’, Pascal, and BASIC pretty well. And I know a little Visual Basic and C++. If possible it would be good if I could find something that's at least reasonably priced. You might be able to tell that it’s been a little while since I’ve done some coding since I’m not up on the latest languages, like C#, Java, Perl, or J. And what is the difference between C++ and C#? And has anyone heard of a language called 'D'? I suppose it’s supposed to be the latest, greatest successor to C++, and C#. Thanks.
