LÖVR Learn Open GL

This repository contains a LÖVR port of the Learn Open GL tutorials.

The goal of the repo is to have a clear understanding on how to port C++-based OpenGL programs to LÖVR. In other words, given a C++ OpenGL program with related shader code, using these tutorials it should be easier to understand how to port the code to LÖVR.

Directory Structure

The directory structure is as follows:

• src/: contains the tuturial source code and some additions for menu navigation in the root program.
• lib/: contains several dependencies, this is code found elsewhere such as lovr-mouse. I've decided to directly integrate the libraries into this repo (no submodules), for easy of use.
• gfx/: contains graphical assets used in tutorials.
• obj/: contains 3D models.

As mentioned before, a basic UI is included for menu navigation. This allows a user to start the main program from the root directory and navigate between the tutorials. Some tutorials include a camera and if so, navigation is possible using mouse and keyboard (<A>, <S>, <D>, <F>). The <escape> button can be pressed to navigate back from a tutorial or menu.

Please note, each tutorial also includes it's own main program, so it's possible to navigate to the directory of a tutorial and start LÖVR from there. Of course, in this case there will be no menu navigation and the <escape> button will exit the tutorial.

Conventions

Some programming conventions used in this project are:

• I've used a class-based approach somewhat similar to the approach described in the Privacy chapter of Programming in Lua.
• Many tutorials contain a shd/ directory, the vertex and fragment shaders are stored inside.
• A tutorial directory contains at least a main.lua file and a tutorial.lua file. The tutorial.lua file contains the source-code equivalent to the C++ source code in the Learn Open GL tutorials.
