## Name

VkOpticalFlowSessionBindingPointNV - Binding points of an optical flow session

Loading… please wait.

## C Specification

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

    // Provided by VK_NV_optical_flow
    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;

## Description

- `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 calcution.

- `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 calcution.

- `VK_OPTICAL_FLOW_SESSION_BINDING_POINT_COST_NV` specifies the binding point for the optional output cost map of default forward flow calcution.

- `VK_OPTICAL_FLOW_SESSION_BINDING_POINT_BACKWARD_COST_NV` specifies the binding point for the optional output cost map of optional backward flow calcution.

- `VK_OPTICAL_FLOW_SESSION_BINDING_POINT_GLOBAL_FLOW_NV` specifies the binding point for the optional global flow value of default forward flow calcution.
