OpenGL Lab

Experimental code using OpenGL via GLEW, GLM, SDL2 and GLFW to test basic aspects of OpenGL and shading via glsl. Currently displays a single rotating object in a window.

Features and Information

• Window creation
• Shader compilation
• Mesh creation (hard coaded vertices or .obj file loading)
• Support for textures
• 3D motion (translation, rotation and scaling)
• Camera system with perspective projection
• Lambertian shading

A test object and texture are provided in the resources file, along with a basic vertex and fragment shader.

Install Guide

It is recommended to follow the installation for your specific platform, building from source is not recommended. Windows installation is not currently supported.

The binary, once built with make can be found in ./build/bin

MacOS

$ brew install glew glm glfw sdl2
$ git clone https://github.com/fraserlove/opengl-lab.git
$ cd opengl-lab
$ make

Debian / Ubuntu

$ sudo apt install libglew-dev libglm-dev libglfw3-dev libsdl2-dev
$ git clone https://github.com/fraserlove/opengl-lab.git
$ cd opengl-lab
$ make

Building from Source

Not recommended as not maintained regularly. For best support use pacakges above. This installs SDL, GLFW and GLEW under the libs folder and not on the users system. Hence no dependencies have to be uninstalled after you are done with the application.

$ git clone --recurse-submodules https://github.com/fraserlove/opengl-lab.git
$ cd opengl-lab
$ sudo make libs
$ make

The following shared libraries under lib/ must be built before the main project can be built:

• SDL lib/SDL/build/.libs/libSDL2.so
• GLFW lib/glfw/src/libglfw.so
• GLEW lib/glew/lib/libGLEW.so
