C Specification

The VkOpticalFlowExecuteInfoNV structure is defined as:

// Provided by VK_NV_optical_flow
typedef struct VkOpticalFlowExecuteInfoNV {
    VkStructureType                sType;
    void*                          pNext;
    VkOpticalFlowExecuteFlagsNV    flags;
    uint32_t                       regionCount;
    const VkRect2D*                pRegions;
} VkOpticalFlowExecuteInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags are the VkOpticalFlowExecuteFlagsNV used for this command.

  • regionCount is the number of regions of interest specified in pRegions.

  • pRegions is a pointer to regionCount VkRect2D regions of interest.

Description

Valid Usage

  • VUID-VkOpticalFlowExecuteInfoNV-regionCount-07593
    regionCount must be 0 if VK_OPTICAL_FLOW_SESSION_CREATE_ALLOW_REGIONS_BIT_NV was not set for VkOpticalFlowSessionNV on which this command is operating

Valid Usage (Implicit)

  • VUID-VkOpticalFlowExecuteInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_OPTICAL_FLOW_EXECUTE_INFO_NV

  • VUID-VkOpticalFlowExecuteInfoNV-pNext-pNext
    pNext must be NULL

  • VUID-VkOpticalFlowExecuteInfoNV-flags-parameter
    flags must be a valid combination of VkOpticalFlowExecuteFlagBitsNV values

  • VUID-VkOpticalFlowExecuteInfoNV-pRegions-parameter
    If regionCount is not 0, pRegions must be a valid pointer to an array of regionCount VkRect2D structures
