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.
