Technical requirements
To use compute shaders, a GPU supporting at least OpenGL 4.3 and/or Vulkan 1.0 is required. Since the source code for the book is written for OpenGL 4.6 and Vulkan 1.1, we are safe here.
You can find the example code in the folder chapter02
, subfolders 01_opengl_computeshader
for OpenGL, and 02_vulkan_computeshader
for Vulkan.
