A simple window for learning OpenGL under Python

Recently watching an OpenGL tutorial: Https://learnopengl.com/Introduction, written in the easy-to-read, very good, and has a Chinese translation version: https://learnopengl-cn.github.io/

Try to re-implement the C + + code in the original tutorial with Python for a deeper learning effect

1. Operating system: Windows 10

2. Install python:https://www.python.org/downloads/, I use 3.6.3

3. Install Pyopengl: After you install Python, the PIP is installed by default, the PIP is added to the default path, and the Windows Command Line window enters pip install Pyopengl

4. Download GLFW: http://www.glfw.org/download.html download 32-bit Windows binaries, next to the compressed file extracted, get the library file Lib-vc2015/glfw3.dll

5. Download the GLFW python interface file: Download the glfw.py in HTTPS://GITHUB.COM/ROUGIER/PYGLFW and place it and the library file from the previous step in the Python default library directory or in the sibling directory of the current development code

6. Create the window.py file with the following code:

#!/usr/bin/env python#-*-coding:utf-8-*-Importsys, OSImportOpengl.gl as GLImportGlfwwin_width= 800Win_height= 600defframebuffer_size_callback (window, width, height): gl.glviewport (0, 0, width, height)defprocessinput (window):ifGlfw.glfwgetkey (window, GLFW.

Glfw_context_version_minor,3) Glfw.glfwwindowhint (GLFW. Glfw_opengl_profile, GLFW. glfw_opengl_core_profile) window= Glfw.glfwcreatewindow (Win_width, Win_height,"Learning OpenGL".

The result of this code execution is as follows:

The above code is the Python implementation of the Hello Window chapter in the OpenGL tutorial, as shown in the original C + + code Https://learnopengl.com/Getting-started/Hello-Window
