Prisma Engine is an OpenGL-based rendering engine designed for creating dynamic 3D applications. It is a personal project created to showcase the capabilities of modern OpenGL. The engine is constantly evolving, so there could be significant changes from one version to another.
- OpenGL 4.6 Support
- Clustered rendering pipelines
- Directional and Omni Lights
- Bullet Physics Integration
- Indirect Drawing
- Omni and Directional lights Shadows
- glTF Loader
- Physically Based Rendering (PBR)
- Image Based Lighting (IBL)
- Scene Graph
- Editor:
- Transform Modifier
- Physics Modifier
- Show Scene Graph
- Change Render Pipeline (Forward clustered/Deferred clustered)
To start using Prisma Engine in your projects, follow these steps:
- Clone the repository:
git clone --recursive https://github.com/deni2312/prisma-engine.git- Install dependencies with vcpkg:
cd prisma-engine
git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg integrate install
cd ..
.\vcpkg\vcpkg install-
Open the project with visual studio
-
Click on main.cpp and run the default scene
-
(Optionally) In
configuration\settings.jsonfile you can change some settings like width, height and camera options.
