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
- Omni shadows and Cascaded shadow maps
- Animations/Animations blending
- Jolt Physics Integration
- Indirect Drawing
- HDR
- Omni and Directional lights Shadows
- glTF Loader
- Physically Based Rendering (PBR)
- Image Based Lighting (IBL)
- Screen space reflections
- Scene Graph
- Bloom
- Postprocessing effects
- Particle effects
- Volumetric Clouds
- Heightmap landscapes
- Procedural texture generation
- Grass optimized by frustum culling
- GPU sorted transparencies
- Thread safe animations
- GPU frustum culled meshes
- Rigidbodies and soft bodies
- Editor:
- Run/Debug modes
- Transform Modifier
- Physics Modifier
- Show Scene Graph
- Animation Viewer
- Change Render Pipeline (Forward clustered/Deferred clustered)
- Texture debugger
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
-
Open Tools -> Options -> Vcpkg then change the vcpkg directory to the path of vcpkg executable
-
Click on main.cpp and run the default scene
-
(Optionally) In
configuration\settings.jsonfile you can change some settings like width, height and name of the window.
An example of a demo scene with deferred clustered shading and forward to run smoothly many lights, with some updates like GPU sorted transparencies, terrain rendering and height based texture, frustum culled grass, that has also animations , it runs at 120 FPS 500+ different animated meshes that run updates in different threads.
