 Welcome! In this series, we enhance a Vulkan renderer with ray tracing features to implement real-time pixel-perfect shadows (with and without transparency) and a bonus reflection effect. You will work with provided scaffolded code (based on the Vulkan Tutorial) and fill in key shader functions following step-by-step instructions.

 The object is rotating, but the shadows are static. This is because we have not yet updated the TLAS to account for the object's animation. The TLAS needs to be rebuilt whenever the object moves or animates, so let's implement that next.

 NOTE: Ray Query vs Ray Tracing Pipeline: Notice how we added a ray tracing effect (shadows) directly in the fragment shader. We did not need a separate ray generation shader or any new pipeline. This is the power of ray queries (also known as inline ray tracing): we integrate ray traversal into our existing rendering pipeline. This keeps the shader logic unified and avoids extra GPU shader launches. On many mobile GPUs, this approach is not only more convenient but necessary: as mentioned, current mobile devices mostly support ray queries and not the full ray pipeline, and they run ray queries efficiently in fragment shaders. This is a key reason we focus on ray queries in this lab.
