# VkTraceRaysIndirectCommandKHR(3) Manual Page

## Name

VkTraceRaysIndirectCommandKHR - Structure specifying the parameters of an indirect ray tracing command

Loading… please wait.

## C Specification

The `VkTraceRaysIndirectCommandKHR` structure is defined as:

    // Provided by VK_KHR_ray_tracing_pipeline
    typedef struct VkTraceRaysIndirectCommandKHR {
        uint32_t    width;
        uint32_t    height;
        uint32_t    depth;
    } VkTraceRaysIndirectCommandKHR;

## Members

- `width` is the width of the ray trace query dimensions.

- `height` is height of the ray trace query dimensions.

- `depth` is depth of the ray trace query dimensions.

## Description

The members of `VkTraceRaysIndirectCommandKHR` have the same meaning as the similarly named parameters of vkCmdTraceRaysKHR.

Valid Usage

- VUID-VkTraceRaysIndirectCommandKHR-width-03638
  `width` must be less than or equal to `VkPhysicalDeviceLimits`::`maxComputeWorkGroupCount`[0] × `VkPhysicalDeviceLimits`::`maxComputeWorkGroupSize`[0]

- VUID-VkTraceRaysIndirectCommandKHR-height-03639
  `height` must be less than or equal to `VkPhysicalDeviceLimits`::`maxComputeWorkGroupCount`[1] × `VkPhysicalDeviceLimits`::`maxComputeWorkGroupSize`[1]

- VUID-VkTraceRaysIndirectCommandKHR-depth-03640
  `depth` must be less than or equal to `VkPhysicalDeviceLimits`::`maxComputeWorkGroupCount`[2] × `VkPhysicalDeviceLimits`::`maxComputeWorkGroupSize`[2]

- VUID-VkTraceRaysIndirectCommandKHR-width-03641
  `width` × `height` × `depth` must be less than or equal to `VkPhysicalDeviceRayTracingPipelinePropertiesKHR`::`maxRayDispatchInvocationCount`
