VkOpticalFlowSessionCreateInfoNV

The VkOpticalFlowSessionCreateInfoNV structure is defined as:

typedef struct VkOpticalFlowSessionCreateInfoNV {
    VkStructureType sType;
    void* pNext;
    uint32_t width;
    uint32_t height;
    VkFormat imageFormat;
    VkFormat flowVectorFormat;
    VkFormat costFormat;
    VkOpticalFlowGridSizeFlagsNV outputGridSize;
    VkOpticalFlowGridSizeFlagsNV hintGridSize;
    VkOpticalFlowPerformanceLevelNV performanceLevel;
    VkOpticalFlowSessionCreateFlagsNV flags;
} VkOpticalFlowSessionCreateInfoNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• width is the width in pixels of the input or reference frame to be bound to this optical flow session.
• height is the height in pixels of the input or reference frame to be bound to this optical flow session.
• imageFormat is the VkFormat of the input and reference frame to be bound to this optical flow session.
• flowVectorFormat is the VkFormat of the flow vector maps (output or hint) to be bound to this optical flow session.
• costFormat is the VkFormat of the cost maps to be bound to this optical flow session.
• outputGridSize is exactly one bit of VkOpticalFlowGridSizeFlagsNV specifying the grid size of the output flow and cost maps to be bound to this optical flow session. The size of the output flow and cost maps is determined by VkOpticalFlowSessionCreateInfoNV::width and VkOpticalFlowSessionCreateInfoNV::height divided by VkOpticalFlowSessionCreateInfoNV::outputGridSize.
• hintGridSize is one exactly bit of VkOpticalFlowGridSizeFlagsNV specifying the grid size of the hint flow vector maps to be bound to this optical flow session. The size of the hint maps is determined by VkOpticalFlowSessionCreateInfoNV::width and VkOpticalFlowSessionCreateInfoNV::height divided by VkOpticalFlowSessionCreateInfoNV::hintGridSize.
• performanceLevel is the VkOpticalFlowPerformanceLevelNV used for this optical flow session.
• flags are the VkOpticalFlowSessionCreateFlagsNV used for this optical flow session.
