VkOpticalFlowSessionBindingPointNV

The optical flow session binding points are defined with the following:

typedef enum VkOpticalFlowSessionBindingPointNV {
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_UNKNOWN_NV = 0,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_INPUT_NV = 1,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_REFERENCE_NV = 2,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_HINT_NV = 3,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_FLOW_VECTOR_NV = 4,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_FLOW_VECTOR_NV = 5,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_COST_NV = 6,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_COST_NV = 7,
    VK_OPTICAL_FLOW_SESSION_BINDING_POINT_GLOBAL_FLOW_NV = 8,
} VkOpticalFlowSessionBindingPointNV;

pub struct OpticalFlowSessionBindingPointNV(u32);

    pub const UNKNOWN: Self = 0;
    pub const INPUT: Self = 1;
    pub const REFERENCE: Self = 2;
    pub const HINT: Self = 3;
    pub const FLOW_VECTOR: Self = 4;
    pub const BACKWARD_FLOW_VECTOR: Self = 5;
    pub const COST: Self = 6;
    pub const BACKWARD_COST: Self = 7;
    pub const GLOBAL_FLOW: Self = 8;
}

• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_INPUT_NV specifies the binding point for the input frame.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_REFERENCE_NV specifies the binding point for the input reference frame.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_HINT_NV specifies the binding point for the optional external hint flow vectors.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_FLOW_VECTOR_NV specifies the binding point for output flow vectors of default forward flow calculation.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_FLOW_VECTOR_NV specifies the binding point for the optional output flow vector map of optional backward flow calculation.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_COST_NV specifies the binding point for the optional output cost map of default forward flow calculation.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_COST_NV specifies the binding point for the optional output cost map of optional backward flow calculation.
• VK_OPTICAL_FLOW_SESSION_BINDING_POINT_GLOBAL_FLOW_NV specifies the binding point for the optional global flow value of default forward flow calculation.
