Debugging Your OpenGL Code // Tips & Tricks!

In this video I describe several methods that you can use in order to debug your OpenGL code, on the application side as well as on the shader side. If you are not familiar with STB image you can check out my texture mapping tutorial at: https://youtu.be/n8t7nvHCqek Get the stb_image_write.h from my git repo below or from the original location: https://github.com/nothings/stb/blob/master/stb_image_write.h Online resource on debugging: https://learnopengl.com/In-Practice/Debugging Make sure to watch all the previous tutorials in the "OpenGL For Beginners" playlist at https://youtube.com/playlist?list=PLA0dXqQjCx0S04ntJKUftl6OaOgsiwHjA Please visit https://ogldev.org to see more of my tutorials on modern OpenGL.
