Efficient Bloom with Gaussian Blur in OpenGL
In this video we learn how to implement Bloom using OpenGL in C++.
🔥Watch the HDR and Tone Mapping tutorial: https://youtu.be/xGArZnotM8k
🔥 See the list of the books that I'm using as background information for my tutorials: https://ogldev.org/books.html. I highly recommend them for learning more about OpenGL and Vulkan. These are affiliate links so if you use them to buy any of the books the price is the same for you and I will get a small commission (thank-you!).
📚 Timecodes 📚
0:00 Intro
0:27 Overview
4:02 Step 1 - render to HDR FB
6:36 Step 2 - bright filter pass
8:34 Full screen vertex shader
10:35 Step 3 - First blur filter
11:14 Gaussian blur
13:49 Step 4 - Second blur filter
14:09 Gaussian weights calculation
15:57 Step 5 - merge with HDR FB
16:25 Outro
Make sure to watch all the previous tutorials in the "Vulkan For Beginners" playlist at https://www.youtube.com/playlist?list=PLA0dXqQjCx0RntJy1pqje9uHRF1Z5vZgA
