-- == Description
--
-- This extension adds two new primitives for ray tracing: a sphere
-- primitive and a linear swept sphere (LSS) primitive. The purpose of the
-- LSS primitive is to enable rendering of high quality hair and fur using
-- a compact primitive representation encoded in the acceleration
-- structure. Sphere primitives are defined by a position and a radius and
-- are a subset of LSS, but are useful in their own right, for example for
-- particle systems.
--
-- This extension adds support for the following SPIR-V extension in
-- Vulkan:
