印象中 Facebook 好似隔了一段日子沒有再向 Snapchat 致敬了，不過今天 Facebook 又再重施故技，為 Facebook Messenger 推出可以使用在視像通話的 AR 濾鏡「 World Effect 」，功能跟 Snapchat 在今年 4 月推出的「 World Lens 」相似。
Messaging is more visual than ever, and features like photos, videos, emojis, stickers and GIFs make Messenger the best place for expressing yourself however you want. And with recent improvements – like the ability to send high resolution photos in Messenger – awesome visual messaging has a home in Messenger. It's been almost exactly a year since we introduced the powerful, native camera for Messenger and given that momentous timing, we're excited to introduce today a new feature for visual messaging — World Effects. World Effects technology enables you to drop 3D objects into your surroundings to capture and share fun moments with your family and friends. For example, add a 3D heart floating over someone's head and then try panning your phone's camera from side to side. Or use an arrow to point to an exact object or location in a panorama so your friend knows what you're referring to. Or better yet, add a new fun, celebratory robot to an otherwise every-day setting and spice things up a bit. (Hint: be sure to try the robot out with your phone's volume turned up – the robot plays three different kinds of music!)We're launching a handful of World Effects to people around the world. In addition to the heart, arrow and robot, you can also try playing around with a unicorn plus word bubbles, like “love,” “bae,” “heart” and “miss you.” To add a World Effect, open the Messenger Camera (from your inbox or from inside an existing conversation by tapping the camera icon), and then scroll to choose from the camera effects. Pick an effect and then tap to add it to your image. We hope you enjoy using these early versions of World Effects in Messenger to bring joy and delight to your communications, especially during this holiday time of year as we re-connect with friends and family and maybe even make new connections. As always, let us know what you think!

World Effect 的功能是當大家進行視像通信時，切換到後鏡頭後，可以把最多 30 個虛擬 3D 物件釘在真實世界的物件上面。在 Facebook 的官方影片中可以看到 3D 的心型圖案放置在大狗的頭頂，而且會隨著狗頭的移動而同時移動， 3D 心型圖案就好似現實存在一樣。
大家只要在 Messenger 打開相機，在下方的鏡頭特效中找出你想要的 AR 特效，貼在人或物件上。只要那物件沒有偏離鏡頭畫面，即使那人移動， 3D 物件仍然會跟著走。現時除了心型圖案外，只有箭頭和機械人可以使用，日後會陸續增加物件。
此外， Facebook 亦同時推出 AR Studio 的正式版讓公眾下載，讓用戶自行製作 Messenger 和直播動畫中可以使用的 AR 特效。
