My take on a 3D game engine, something i have been working on for quite a while as a hobby project also as a school assignment. Mainly working on it to learn game engine development and modern c++ techniques. Key focus being rouge like mechanics. The current version is very barebones and more like a OpenGL wrapper, the key tasks other than planned features would be:
- Better error handling and asserts on the release build
- Rditor and engine separation
- Scene graph
- ECS integration
- Scene Renderer
- Deffered Shading
- Shadow Mapping
- Post Processing (AO, Bloom, ect...)
- Multithreaded Game Event System
- Multithreaded Rendering Queue
- Procedural Level/World Generation
- Audio Engine (OpenAL)
- Networking Layer (Asio)
- Embeded Scripting Language probably lua
Clone the repository and get all the submodules
git clone --recursive https://github.com/stojanov/prism
cd prismIt is ment to but run directly into an IDE that supports the cmake system, you can also try to generate the project files manually
# Unix
cmake ./
# Windows
cmake -G "Visual Studio 16" -A "Win64" ./Once you compile you will be ready to peek around the source code, the best way to start is of course main.cpp found under src/game/main.cpp:
Prism::Application app(1280, 720, "Prism");
app.CreateLayer<Prism::Examples::VoxelExample>("Voxel Example");
app.Run();
Here we can attach a layer/state to be run on the engine, create a layer and plug it into the Prism::Application, that should fairly simple just follow the interface
src/prism/Interfaces/ILayer.h which contains the base methods for running a layer.
Keep in mind that every layer should have a constructor that recives a Ref<Core::SharedContext> and a name,
you can check out some of the src/prism/Examples for implementing a layer.
-
- Voxel mesh generation based on a height map(Perlin Noise) and infinite world generation
- All of the voxel modules can be found under the
src/prism/Voxels - Chunk mesh generation only supports generating a mesh for a height map but will add more features in the future
- Chunk mesh generation offloaded into a background thread via a thread pool can be found in
src/prism/Voxels/ChunkManager.cpp
- Major Refactor/Restructure
- Camera System/Controller Rework
- Entity Component System
- Base Editor Controls
- Better documentation
- Added a base entity component system (The system part is still under development)
- Added phmap as a module
