Understanding Alpha, Beta, and Gamma:<\/strong><\/p>\n

The API uses a 3D coordinate system (as illustrated below) to define these angles:<\/p>\n

<\/p>\n

\n
• Alpha:<\/strong> Rotation around the z-axis (0-360 degrees). 0 degrees points the device's top towards Earth's North Pole.\n<\/li>\n
• Beta:<\/strong> Rotation around the x-axis (-180-180 degrees). 0 degrees means the device is parallel to the Earth's surface.\n<\/li>\n
• Gamma:<\/strong> Rotation around the y-axis (-90-90 degrees). 0 degrees means the device is parallel to the Earth's surface.\n<\/li>\n<\/ul>\n

  The deviceorientation<\/code> Event Handler:<\/strong><\/p>

  This function processes the deviceorientation<\/code> event, updating the canvas based on the received alpha, beta, and gamma values.<\/p>\n

  if (window.DeviceOrientationEvent) {\n  \/\/ Browser supports DeviceOrientation\n} else {\n  console.log(\"Device Orientation not supported by this browser.\");\n}<\/pre>\n
