This is a toy "game engine" written in Rust. It is not a proper game engine, as currently the game and the engine are coupled together, so a game would be implemented by cloning the project and implementing the game in the main loop. This coupling is not due to any technical limitations, however; decoupling is just something I haven't gotten around to yet.
- Supports OpenGL
- The engine supports rendering 3D objects by either manually specifying vertices or by supplying an
objfile containing the vertices. The objects must implement theGameObjecttrait, which allows the engine to get the necessary information to draw and update the object. - Text rendering is supported.
- Texture and glyph caching
- A perspective camera is provided
- A 2D GUI shader and a 3D perspective shader are provided. An unlit fragment shader is also provided. Both colors and textures can be used with the unlit fragment shader.
Running the engine in it's current state will run an example. The example consists of a grid, a rotating cube, some text, and the ability to translate (left click), rotate (right click), and zoom (scroll wheel) the camera:
To add your own objects, implement GameObject on them using Grid and Cube as an example.
While I'm not sure if development will continue on this project, if it did these are some features I would add:
- Lighting objects/shaders
- Diffuse and specular shaders
- An orthographic camera
- Easier ways to transform (translate, rotate and scale) objects
- Quaternions
- Frustrum culling
- Render children objects relative to parent instead of in absolute coordinates
