# Ray Query
This extension is allowing to execute ray intersection queries in any shader stages. In this example, we will add
ray queries to the fragment shader to cast shadow rays.
ray queries [(GLSL_EXT_ray_query)](https://github.com/KhronosGroup/GLSL/blob/master/extensions/ext/GLSL_EXT_ray_query.txt) to the fragment shader to cast shadow rays.
In the contrary to all other examples, with this one, we are removing code. There are no need to have a SBT and a raytracing pipeline, the only thing that
will matter, is the creation of the acceleration structure.
Starting from the end of the tutorial, [ray_tracing__simple](https://github.com/nvpro-samples/vk_raytracing_tutorial/tree/master/ray_tracing__simple) we will remove
Starting from the end of the tutorial, [ray_tracing__simple](https://github.com/nvpro-samples/vk_raytracing_tutorial_KHR/tree/master/ray_tracing__simple) we will remove
all functions that were dedicated to ray tracing and keep only the construction of the BLAS and TLAS.
