## C Specification

To dispatch ray tracing, with some parameters sourced on the device, use:

// Provided by VK_KHR_ray_tracing_pipeline
void vkCmdTraceRaysIndirectKHR(
VkCommandBuffer                             commandBuffer,
const VkStridedDeviceAddressRegionKHR*      pRaygenShaderBindingTable,
const VkStridedDeviceAddressRegionKHR*      pMissShaderBindingTable,
const VkStridedDeviceAddressRegionKHR*      pHitShaderBindingTable,
const VkStridedDeviceAddressRegionKHR*      pCallableShaderBindingTable,
VkDeviceAddress                             indirectDeviceAddress);

## Parameters

• commandBuffer is the command buffer into which the command will be recorded.

• pRaygenShaderBindingTable is a VkStridedDeviceAddressRegionKHR that holds the shader binding table data for the ray generation shader stage.

• pMissShaderBindingTable is a VkStridedDeviceAddressRegionKHR that holds the shader binding table data for the miss shader stage.

• pHitShaderBindingTable is a VkStridedDeviceAddressRegionKHR that holds the shader binding table data for the hit shader stage.

• pCallableShaderBindingTable is a VkStridedDeviceAddressRegionKHR that holds the shader binding table data for the callable shader stage.

• indirectDeviceAddress is a buffer device address which is a pointer to a VkTraceRaysIndirectCommandKHR structure containing the trace ray parameters.

## Description

vkCmdTraceRaysIndirectKHR behaves similarly to vkCmdTraceRaysKHR except that the ray trace query dimensions are read by the device from indirectDeviceAddress during execution.
