Welcome to OpenGL by Examples using C++.

Each example will get more complex. I am using OpenGL to improve my linear algebra intuition while having some fun.

Setup I am using

1. Mac OSX
2. OpenGL 2.1
3. C++ 11
4. cmake 3.7

Libraries you'll need

1. GLFW (for window and context creation)
2. glew (GL extension wrangler)
3. glm (GL Mathematics)
4. OpenGL

If you're on a mac, do the following.

1. brew install glfw
2. brew install glew
3. brew install glm
4. OpenGL comes installed already.
   • You just have to link in your cmake like link_libraries(GLFW glew "-framework OpenGL")

How to Build and Run

1. Clone this repo and cd in this repo.
2. Run mkdir build && cd build
3. Run cmake .. && make

Examples in order

0. Show what version of OpenGL you're running.
1. Show how to create a GLFW window and context.
2. Show how to use glew.
3. Show how to use legacy fixed function pipeline to render aka immediate mode.
