Selecting 3D Objects With The Mouse Using OpenGL // OpenGL Tutorial #31
In this video we're going to learn how to use render to texture in order to implement selection of a 3D objects using the mouse in OpenGL. This tutorial assumes knowledge about how I load 3D models using Assimp (check out my Assimp tutorial • Loading Models Using Assimp // OpenGL... ).
Make sure to watch all the previous tutorials in the "OpenGL For Beginners" playlist at • OpenGL for Beginners
