Castor3D

Castor3D is a 3D engine written in C++ 17. It works on Windows and GNU/Linux. It relies on Ashes as a rendering API, allowing Vulkan, Direct3D 11, and OpenGL. The project itself is compilable on supported platforms using CMake (\ref build).

Features

Deferred rendering for opaque objects.
Blended Weighted rendering for transparent objects.
Normal mapping.
Shadow Mapping (allowing to choose between Raw, PCF or Variance Shadow Maps).
Parallax Occlusion mapping.
Screen Space Ambient Occlusion (using Scalable Ambiant Obscurance).
Reflection/Refraction Mapping.
PBR rendering (Metallic and Specular workflows), and Phong/Blinn-Phong rendering.
HDR rendering with various tone mapping operators.
Screen Space Subsurface Scattering (without backlit transmittance yet).
Volumetric Light Scattering for the directional light source, if it projects shadows.
Cascaded Shadow Maps for the directional light source.
Global Illumination, through Light Propagation Volumes (layered or non layered, with or without geometry injection), or through Voxel Cone Tracing.
Frustum culling.
Scene graph.
Render graph.
Modular architecture through plug-ins.
Shaders are generated automatically from pipeline configuration.
Shaders are writable directly from C++ code.
Scenes are described using a text format easily comprehensible and extensible.
Asynchronous (user defined) or synchronous (thread) rendering.
