I am trying to write individual pixels onto the screen, preferrably in a window, but that isnt necessary. I need no other drawing tools, just pixels.
I need to be able to do this very fast as I want to display the ouput from things like fluid dynamics systems in real time and other things which will gobble up processing power.
I know I can write to the video memory, but I do not understand how.
I am pretty new to C++ but have coded before, so I understand the basics at least.
Can anyone point me in the direction of some good resources?
I have looked at opengl, but cannot get writing pixels to work, I can do points, but these are incredibly slow.
I am coding in dev-cpp, would anyone recommend any other good packages (free ones)?
