VkTraceRaysIndirectCommandKHR(3)

Name

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

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
