vierkant

• vierkant is a Vulkan 1.3 based rendering library written in C++20.
• win64: linux:

rendering backends

• gpu-driven rasterizer with compute-based frustum/occlusion-culling
• optional support for meshlet-based pipelines (using VK_EXT_mesh_shader)
• pathtracer using VK_KHR_ray_tracing_pipeline, useful for comparing against a groundtruth

features

• load .hdr panoramas as mip-mapped cubemaps
• utils for lambert- and GGX-convolutions used by rasterizer
• glTF 2.0 via tinygltf
  • broad glTF2 coverage, including many KHR extensions (transmission, volumes, iridescence, ...)
• pragmatic+easy interface, thanks imgui
• entity-component-system (registry/entity) provided by entt

tools

built by default, disable with -DBUILD_VIERKANT_TOOLS=OFF

• vierkant_ed
  • 3d-viewer/editor with the raster- and raytracing backends
  • view a gltf2-model using an HDR-background: ./vierkant_ed foo.gltf bar.hdr
  • drag&drop model/image-files, save settings with 's'
• cache_4km — bake self-contained .4km asset-bundles from model-files
• pbr_thumbnailer — 3d-model thumbnailer, rasterization or path-tracer backend

nightly builds:

• linux: vierkant_ed_linux_x64.tar.xz
