# SimpleGLRenderer
## Info
### Description
A simple renderer build with OpenGL on Linux (Ubuntu).
### Setup
Clone the repo including submodules:
```bash
git clone --recurse-submodules
cd
```
If you already cloned without submodules, run:
```bash
git submodule update --init --recursive
```
To update later:
```bash
git pull --recurse-submodules
git submodule update --recursive --remote
```
Then install the following dependencies (assumes Ubuntu 24 or later):
`sudo apt install libglm-dev` -> math lib for opengl
`sudo apt install libglfw3-dev` -> glfw3
`sudo apt install libassimp-dev` -> assimp
### Building the project
```bash
cd build
cmake ..
make
./renderer
```
### Features
- **Asset Loading:** Load 3D models via [Assimp](https://www.assimp.org/).
- **Shaders & Lighting:** Phong shading with a flexible light manager system.
- **User Interface:** Integrated UI using [Dear ImGui](https://github.com/ocornut/imgui).
- **Window Management:** Abstracted window handling and OpenGL context setup.
- **Utilities:** Helper functions for loading models and other assets.
- **Camera:** First-person camera with Unreal Engine-style controls (hold right mouse button to navigate).
- **Scene Graph:** Basic scene graph with entities, transforms, meshes, models, and hierarchical structure.
- **Mesh Factory:** Easily create common 3D geometry like boxes, planes, and spheres.
### Styleguide
Using VSCode, the C++ style of choice is **Chromium**.
