C Specification

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

// Provided by VK_KHR_ray_tracing_maintenance1 with VK_KHR_ray_tracing_pipeline
void vkCmdTraceRaysIndirect2KHR(
    VkCommandBuffer                             commandBuffer,
    VkDeviceAddress                             indirectDeviceAddress);

Parameters

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

  • indirectDeviceAddress is a buffer device address which is a pointer to a VkTraceRaysIndirectCommand2KHR structure containing the trace ray parameters.

Description

vkCmdTraceRaysIndirect2KHR behaves similarly to vkCmdTraceRaysIndirectKHR except that shader binding table parameters as well as dispatch dimensions are read by the device from indirectDeviceAddress during execution.
