Example

The example shows how to draw the texture with the ImageView class.

Draw the image texture

First, add a WebcamSource field to get frames from a live feed and an ImageViewfield to draw the texture for Unity to serialize.

[SerializeField] private ImageView _image;
[SerializeField] private WebcamSource _webcam;

The easiest way to draw the image texture is by providing directly a WebcamSource object.

_image.Load(_webcam);

Alternatively, you can provide the color array of the texture.

_image.Load(_webcam.Pixels, _webcam.Width, _webcam.Height);

Get the local position of a finger joint

The FingerJoint class returns the joint's 2D position in pixels relative to the camera's dimensions. To represent this position on an ImageView texture, which may vary in size, the GetPosition method scales the joint's coordinates to match the texture's current width and height.

// Get the finger joint from the detected hand.
FingerJoint pinkyDip = hand.FingerJoints[FingerJointType.PinkyDIP];

// Get the original 2D position (pixels in the camera frame).
Vector2 original_position = pinkyDip.Position2D;

// Get the local 2D position (pixels in the ImageView texture).
Vector2 local_position = image.GetPosition(original_position);
