+
+Kajiya by [@h3r2tic]
+is a real-time global illumination renderer.
+
+It utilizes Vulkan Ray Tracing via [ash][ash] and [hassle-rs][hassle-rs] to
+implement multi-bounce light transport in fully dynamic scenes. By shooting
+only two rays per pixel on average, it keeps performance high; thanks to a
+voxel-based light cache and extensive spatio-temporal filtering, it keeps
+noise low. It supports physically-based rendering of [GLTF][gltf-rs] scenes,
+and achieves a close match to reference path-tracing.
+
+Kajiya is still in its infancy, and not yet available to the public, but you
+can get glimpses of its development by following the author on [Twitter][h3r2tic-twitter].
