Null Engine is a basic 3D Graphics Engine for game development. It has been developed by a single Bachelor's degree in Video Game Design and Development student at UPC CITM Tech Talent Center in Barcelona.
It has been coded from scratch in C and C++ along with the following libraries:
- Standard Template Library
- Simple DirectMedia Layer
- OpenGL v4.6
- Glew v2.1.0
- ImGui v1.79 (Docking Branch)
- ImGuizmo v1.61
- MatGeoLib v1.5
- PhysFS v3.0.2
- Parson v1.1.0
- Assimp v3.1.1
- DevIL v1.8.0
- mmgr
- Github: BarcinoLechiguino (https://github.com/BarcinoLechiguino)
- Repository: https://github.com/BarcinoLechiguino/NULL_Engine
Implemented features (As of 01/11/2020)
- Library Integration (All o the stated in the introduction).
- ImGui UI Display & Structure
- Configuration & Console
- 3D Model Loading
- Image Loading
- Drag & Drop Models and textures from a directory.
- GameObject and Components
- Hierarchy & Inspector
- Main Menu Toolbar: Placed at the top of the window. It has various menu items that allow to exit the engine, open/close editor panels and show some primitive examples.
- Configuration Panel: Placed at the right side of the window. It has multiple collapsing headers that display different values and parameters of each existing module.
- Hierarchy Panel: Placed at the left side of the window. It shows all the game objects that are currently placed in the current scene. Upon clicking any of them the Inspector panel will show all the components the selected game object has.
- Inspector Panel: Placed at the right side of the window (along with Configuration). It shows the components of a selected game object. The components are Transform, Mesh and Material.
- **Console Panel: ** Placed at the bottom of the window. It outputs information about the state of the engine: Loading&Saving, Importing models and textures...
Currently there are no innovations to speak of.
No previous installation is required to use the engine, just download the latest RELEASE from the repository and execute the "NULL_Engine.exe" executable, which you will find in the "NULLEngine" folder.
