C++ equivalent to directly writing to screen in assembly

Question

In 68000 assembly you utilised techniques to identify the screen address and then write your image to the screen. I would like to know how this could be done using C++ or similar. Can anyone help with this or point me at such a tutorial?

I used to develop small games/demos in 68000 assembly many years ago. I've recently taught myself c++ as well as playing with c#. I appreciate there's openGL and Direct X available among many other libraries/engines that I could use to do the work for me but I'm simply interested in how I could essentially place a pixel not the screen at the lowest level within C++ or similar. Its less practical but more educational for me.

I'm assuming in a Windows environment I would be looking to use an OS API to do this but which? Or is my answer actually openGL or DirectX. If so, whats the best method to place a single pixel on an otherwise blank display?

Thanks in advance....

Answer 1

Graphics is not part of standard C++. You have to use 3rd party libraries to do this. There are several choices. You already mentioned OpenGL and DirectX, which I consider quite low-level. If you want to go even lower level, you can use the API given by your OS.
