func transformToTextureCoordinates(screenCoordinates: CGPoint) -> CGPoint {
    let hitTestResults = sceneView.hitTest(screenCoordinates, options: nil)
    guard let result = hitTestResults.first else {
        return CGPoint(x: -1, y: -1)
    }
    let textureCoordinates = result.textureCoordinates(withMappingChannel: 0)
    return CGPoint(x: textureCoordinates.x * textureImage.size.width, y: textureCoordinates.y * textureImage.size.height)
}
