which establishes the relationship +between the ray tracing pipeline and the acceleration structures that were +built for the ray tracing query. +It indicates the shaders that operate on each geometry in an acceleration +structure. +In addition, it contains the resources accessed by each shader, including +indices of textures and constants. +The application allocates and manages _shader binding tables_ as +elink:VkBuffer objects. + +Each entry in the shader binding table consists of pname:shaderHeaderSize +bytes of data as queried by vkGetRayTracingShaderHandlesNV to refer to the +shader that it invokes. +The remainder of the data specified by the stride is application-visible +data that can be referenced by a shaderRecordNV block in the shader. + +The shader binding tables to use in
