static void TransformARCoordinates2D
(
    EGoogleARCoreCoordinates2DType InputCoordinatesType,
    const TArray< FVector2D > & InputCoordinates,
    EGoogleARCoreCoordinates2DType OutputCoordinatesType,

)

Remarks

Transforms an array of 2D coordinates into a different 2D coordinate system. This will account for the display rotation, and any additional required adjustment.

Some examples of useful conversions: To transform screen space UVs for texture space UVs to rendering pass-through camera texture: Viewport -> Texture; To transform a point found by a computer vision algorithm in the pass-through camera image into a point on the viewport: Image -> Viewport;

Parameters

Parameter

Description

InputCoordinatesType

The coordinate system used by InputCoordinates.

InputCoordinates

The input 2d coordinates.

OutputCoordinatesType

The coordinate system to transform to.

OutputCoordinates

The output 2d coordinates.
