Castor3D
Castor3D is a 3D engine written in C++ 20. It works on Windows and GNU/Linux and using Vulkan as rendering API. The project itself is compilable on supported platforms using CMake and vcpkg (\ref build).
Features
- Clustered lighting to compute all light sources.
- Using a visibility buffer for opaque objects.
- Blended Weighted rendering for transparent objects.
- Normal mapping (using Mikktspace or explicit bitangents specification).
- 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 and various colour grading 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. (Scene File)
- Synchronous (user defined) or asynchronous (thread) rendering.
- Using Mesh and Task shaders, if available.
- GUI primitives.
