Castor3D

Castor3D is a 3D engine written in C++ 17.
It works on Windows and also on GNU/Linux.
It relies on RendererLib as a rendering API, allowing Vulkan, OpenGL 3.X and OpenGL 4.X.
It is still a work in progress, feel free to contribute!

Features

• Deferred rendering.
• Normal mapping.
• Parallax Occlusion mapping.
• Screen Space Ambient Occlusion (using Scalable Ambiant Obscurance implementation).
• Shadow Mapping (allowing to choose between Raw, PCF or Variance Shadow Maps).
• Reflection/Refraction Mapping.
• PBR rendering (Metallic and Specular workflows), and Legacy rendering.
• HDR rendering with various tone mapping operators.
• Screen Space Subsurface Scattering (without backlit transmittance yet).
• Volumetric Light Scattering for directional light source projecting shadows.
• Cascaded Shadow Maps for directional light sources.
• Frustum culling.
• Scene graph.
• Modular architecture through plug-ins.
• Shaders are generated automatically from material and pass configuration.
• Shaders are writable directly from C++ code.
