Fast pixel drawing on the screen

Question

I need to fill a window with pixels, very fast of course. This is for an 'old school' project with software 3D graphics (proof of concept).

The requirements are:

• Pointer to the screen buffer to write colors and a method to display it

• No OpenGL, Direct3D or SDL

• Pure WinAPI

Question: How do I draw pixels on a window with WinAPI?

Answer 1

• CreateDIBSection to create a HBITMAP bitmap with handle along with raw pointer to bits
• BitBlt to copy data between HDC device contexts, from a device context with the bitmap (see above) selected into, to the other one associated with the window you are to "paint on"
