Black Key

A realtime rendering engine leveraging modern vulkan and C++ features built as a research project.

All the following scenes are rendered in engine:

Currently supported features

Graphics

• Physically based rendering using a cook-torrence brdf
• Image based lighting
• Cascaded shadow maps + PCF filtering
• GLTF loading suppport via Fastgltf
• Early depth testing via Z-prepass
• HDR + options for Filmic/Uncharted/unreal tonemappers
• CPU side Frustum culling
• Multisampling anti-aliasing
• normal mapping
• Ktx Texture support for skybox
• Transparency

API Features

• Buffer device addressing for programmable vertex pulling
• Dynamic Rendering

Roadmap

• Clustered forward shading
• GPU driven rendering
• Move Frustum culling to a compute shader
• occlusion culling
• Bindless Resources
• Bloom
• HBAO/GTAO/SSAO
• Async compute
• Global illumination(SSGI(HBIL/SSIL)/Voxel GI/RSM/Deep G-buffers/light propagation volumes)
• Render graph
• shader hot reloading
• editor

Things to look into

• visibility buffer rendering
• virtual shadow maps
• Radiance cascades
