C Specification

Bits which can be set in VkOpticalFlowImageFormatInfoNV::usage, controlling optical flow usage, are:

// Provided by VK_NV_optical_flow
typedef enum VkOpticalFlowUsageFlagBitsNV {
    VK_OPTICAL_FLOW_USAGE_UNKNOWN_NV = 0,
    VK_OPTICAL_FLOW_USAGE_INPUT_BIT_NV = 0x00000001,
    VK_OPTICAL_FLOW_USAGE_OUTPUT_BIT_NV = 0x00000002,
    VK_OPTICAL_FLOW_USAGE_HINT_BIT_NV = 0x00000004,
    VK_OPTICAL_FLOW_USAGE_COST_BIT_NV = 0x00000008,
    VK_OPTICAL_FLOW_USAGE_GLOBAL_FLOW_BIT_NV = 0x00000010,
} VkOpticalFlowUsageFlagBitsNV;

Description

  • VK_OPTICAL_FLOW_USAGE_INPUT_BIT_NV specifies that the image can be used as input or reference frame for an optical flow operation.

  • VK_OPTICAL_FLOW_USAGE_OUTPUT_BIT_NV specifies that the image can be used as output flow vector map for an optical flow operation.

  • VK_OPTICAL_FLOW_USAGE_HINT_BIT_NV specifies that the image can be used as hint flow vector map for an optical flow operation.

  • VK_OPTICAL_FLOW_USAGE_COST_BIT_NV specifies that the image can be used as output cost map for an optical flow operation.

  • VK_OPTICAL_FLOW_USAGE_GLOBAL_FLOW_BIT_NV specifies that the image can be used as global flow vector for an optical flow operation.
