# 👾 opengl-imgui-cmake-template
A quick and easy way to get started using OpenGL 3.3 Core Profile together with [imgui](https://github.com/ocornut/imgui) in a CMake environment.
This template only contains a wrapper class for shaders, and one for the window with appropriate `Initialize/LoadContent/Update/Render` as a game loop.
The shader class allows for **hot-reloading** of the fragment shader, so whenever you modify the `testing.fs` file in the `build/resources/shaders/` directory, the shader will automagically be reloaded!
**NOTE:** The shader files in `resources/shaders/` are copied into the `build/` directory upon build, so if you want to save your hot-reloaded changes, then you must also modify the shaders in `resources/shaders/` directory.
## Getting started
1. Create a new repo by clicking `Use this template` up to the right!
2. Download some [GLFW pre-compiled binaries](https://www.glfw.org/download) and put the `libglfw3.a` file in `libs/glfw/`.
3. Compile with CMake and then run it! Piece of cake!
## Remarks
* Uses [imgui version 1.83](https://github.com/ocornut/imgui/releases/tag/v1.83)
* Has only been tested on MingW64 compiler for Windows (so it may require some fixing for it to work for gcc or clang)
