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:

1. Clone the repository:

git clone --recursive https://github.com/deni2312/prisma-engine.git

2. 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

3. Open the project with visual studio

4. Click on main.cpp and run the default scene

5. (Optionally) In configuration\settings.json file you can change some settings like width, height and camera options.

An example of a Sponza scene that utilizes 1000 point lights through clustered shading, with some post-processing, and includes animations taken from Mixamo. (Click on the image for the youtube video)
