C Specification

To create ray tracing pipelines, call:

// Provided by VK_NV_ray_tracing
VkResult vkCreateRayTracingPipelinesNV(
    VkDevice                                    device,
    VkPipelineCache                             pipelineCache,
    uint32_t                                    createInfoCount,
    const VkRayTracingPipelineCreateInfoNV*     pCreateInfos,
    const VkAllocationCallbacks*                pAllocator,
    VkPipeline*                                 pPipelines);

Parameters

  • device is the logical device that creates the ray tracing pipelines.

  • pipelineCache is either VK_NULL_HANDLE, indicating that pipeline caching is disabled, or to enable caching, the handle of a valid VkPipelineCache object. The implementation must not access this object outside of the duration of this command.

  • createInfoCount is the length of the pCreateInfos and pPipelines arrays.

  • pCreateInfos is a pointer to an array of VkRayTracingPipelineCreateInfoNV structures.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pPipelines is a pointer to an array in which the resulting ray tracing pipeline objects are returned.

Description

Pipelines are created and returned as described for Multiple Pipeline Creation.

Valid Usage
  • VUID-vkCreateRayTracingPipelinesNV-device-09677
    device must support at least one queue family with the VK_QUEUE_COMPUTE_BIT capability

  • VUID-vkCreateRayTracingPipelinesNV-flags-03415
    If the flags member of any element of pCreateInfos contains the VK_PIPELINE_CREATE_DERIVATIVE_BIT flag, and the basePipelineIndex member of that same element is not -1, basePipelineIndex must be less than the index into pCreateInfos that corresponds to that element

  • VUID-vkCreateRayTracingPipelinesNV-flags-03416
    If the flags member of any element of pCreateInfos contains the VK_PIPELINE_CREATE_DERIVATIVE_BIT flag, the base pipeline must have been created with the VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT flag set

  • VUID-vkCreateRayTracingPipelinesNV-flags-03816
    flags must not contain the VK_PIPELINE_CREATE_DISPATCH_BASE flag

  • VUID-vkCreateRayTracingPipelinesNV-pipelineCache-02903
    If pipelineCache was created with VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT, host access to pipelineCache must be externally synchronized

  • VUID-vkCreateRayTracingPipelinesNV-pNext-09616
    If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, pipelineCache must be VK_NULL_HANDLE

  • VUID-vkCreateRayTracingPipelinesNV-pNext-09617
    If a VkPipelineCreateFlags2CreateInfoKHR structure with the VK_PIPELINE_CREATE_2_CAPTURE_DATA_BIT_KHR flag set is included in the pNext chain of any element of pCreateInfos, pipelineCache must be VK_NULL_HANDLE

  • VUID-vkCreateRayTracingPipelinesNV-binaryCount-09620
    If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT must not be set in the flags of that element

  • VUID-vkCreateRayTracingPipelinesNV-binaryCount-09621
    If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATION_FEEDBACK_BASE_PIPELINE_ACCELERATION_BIT must not be set in the flags of that element

  • VUID-vkCreateRayTracingPipelinesNV-binaryCount-09622
    If VkPipelineBinaryInfoKHR::binaryCount is not 0 for any element of pCreateInfos, VK_PIPELINE_CREATE_FAIL_ON_PIPELINE_COMPILE_REQUIRED_BIT_EXT must not be set in the flags of that element

  • VUID-vkCreateRayTracingPipelinesNV-pNext-10150
    If a VkPipelineCreateFlags2CreateInfoKHR structure is included in the pNext chain of any element of pCreateInfos, VK_PIPELINE_CREATE_2_CAPTURE_DATA_BIT_KHR flag must not be set

Valid Usage (Implicit)
  • VUID-vkCreateRayTracingPipelinesNV-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreateRayTracingPipelinesNV-pipelineCache-parameter
    If pipelineCache is not VK_NULL_HANDLE, pipelineCache must be a valid VkPipelineCache handle

  • VUID-vkCreateRayTracingPipelinesNV-pCreateInfos-parameter
    pCreateInfos must be a valid pointer to an array of createInfoCount valid VkRayTracingPipelineCreateInfoNV structures

  • VUID-vkCreateRayTracingPipelinesNV-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkCreateRayTracingPipelinesNV-pPipelines-parameter
    pPipelines must be a valid pointer to an array of createInfoCount VkPipeline handles

  • VUID-vkCreateRayTracingPipelinesNV-createInfoCount-arraylength
    createInfoCount must be greater than 0

  • VUID-vkCreateRayTracingPipelinesNV-pipelineCache-parent
    If pipelineCache is a valid handle, it must have been created, allocated, or retrieved from device

Return Codes
On success, this command returns
  • VK_SUCCESS

  • VK_PIPELINE_COMPILE_REQUIRED_EXT

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_INVALID_SHADER_NV
