This viewer was created as part of a school project during my third year of engineering school. We had to understand the glTF file structure to be able to draw the 3D model then, we had to add some element like the metalic/roughness material or the normal map.
To do this, we used C++, openGL, ImGui and the tinyglTF library.
We were a group of 2 and we were working together as pair programmer.
