# NVIDIA Vulkan Trace Rays Indirect Tutorial
|
|
This is an extension of the [Vulkan ray tracing tutorial](https://nvpro-samples.github.io/vk_raytracing_tutorial_KHR/vkrt_tutorial.md.html).
|
|
|
|
We will discuss the `vkCmdTraceRaysIndirectKHR` command, which allows the
|
|
`width`, `height`, and `depth` of a trace ray command to be specifed by a
|
|
buffer on the device, rather than directly by the host. As a demonstration,
|
|
this example will add colorful lanterns to the scene that add their own light
|
|
and shadows, with a finite radius of effect. A compute shader will calculate
|
|
scissor rectangles for each lantern, and an indirect trace rays command will
|
|
dispatch rays for lanterns only within those scissor rectangles.
