toViewCoordinatesTransformation

fun toViewCoordinatesTransformation(context: Context, cameraId: String, intrinsicParameters: PinholeCameraIntrinsicParameters, result: ProjectiveTransformation2D)

Creates 2D transformation to convert 2D point coordinates from OpenGL coordinates to Android view coordinates.

It must be noticed that OpenGL uses a right handed coordinate system where y coordinates increase upwards, whereas Android uses y coordinates that increase downwards and takes into account screen and camera sensor orientation.

This method takes into account current display and camera orientation.

Parameters

context

Android context.

cameraId

A camera id.

intrinsicParameters

camera intrinsic parameters.

result

instance where computed transformation will be stored.

fun toViewCoordinatesTransformation(context: Context, characteristics: CameraCharacteristics, intrinsicParameters: PinholeCameraIntrinsicParameters, result: ProjectiveTransformation2D)
