OpenGL programming based on MFC Chinese WORD version
Introduction
update time：2024-02-26This document mainly talks about OpenGL programming based on MFC; GDI draws through the device handle (Device Context, hereinafter referred to as "DC"), while OpenGL requires a rendering environment (Rendering Context, hereinafter referred to as "RC"). Each GDI command requires a DC to be passed to it, but unlike GDI, OpenGL uses the current drawing context (RC). Once a current RC is specified in a thread, all subsequent OpenGL commands in this thread use the same current RC. While multiple RCs can be used in a single window, there is only one current RC in a single thread. Below I will first generate an OpenGL RC and make it the current RC, which will be divided into three steps: set the window pixel format; generate RC; set as the current RC. I hope this document will help friends in need; interested friends can come and take a look.
