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 (cf. 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. (Scene File)
• Asynchronous (timers) or synchronour (thread) rendering.
• Using Mesh and Task shaders, if available.
