|Hello, AR World!

Using an HTML canvas as the texture for a cube; creating an animation ("bouncing block") on the canvas and updating the cube texture.
A cube is attached to a kanji marker. Red, yellow, and blue squares are attached to barcode markers 0, 1, and 2. The color of the cube changes depending on which combination of the markers is visible.
|Persistence and Following
A green square is attached to a marker. If the marker is no longer visible, the square turns red and remains in the last known position of the marker. If the marker then becomes visible again, the square turns green and moves (lerps) to the new position.
|Line between two markers
Drawing a line between the centers of barcode markers 0 and 1. (Updates line geometry vertices.)
|Cylinder between two markers
Since lines can be difficult to see, drawing spheres at the centers of barcode markers 0 and 1, and creating a cylinder between the them. (Reorients and rescales the cylinder depending on the distance between the markers.)
