vkCreateRayTracingPipelinesNV(3)

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_BIT 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-pCreateInfos-11414
If any element of pCreateInfos sets VK_PIPELINE_CREATE_2_DESCRIPTOR_HEAP_BIT_EXT and includes embedded sampler mappings, there must be less than (maxSamplerAllocationCount - (minSamplerHeapReservedRangeWithEmbedded / samplerDescriptorSize)) VkSampler objects currently created on the device
VUID-vkCreateRayTracingPipelinesNV-pCreateInfos-11429
If any element of pCreateInfos sets VK_PIPELINE_CREATE_2_DESCRIPTOR_HEAP_BIT_EXT and includes embedded sampler mappings, this command must not cause the total number of unique embedded samplers in pipelines and shaders on this device to exceed maxDescriptorHeapEmbeddedSamplers
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)

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
