どうも穴澤です。
先日「Image Tracking」サンプルの認識画像を変更してみて、他の画像を認識させました。
今回は表示するオブジェクトをサンプルの恐竜から変更してみようと思います。
画像（マーカー）を認識したときに表示される3Dオブジェクトを変更したいと思います。
今回表示する3Dオブジェクトは、大阪といえばこのキャラクターでしょう。
作り方は簡単です。
弊社の代表が趣味で作っていたので、いただきました。

変更点は46行目を作成したgltfファイルに置き換えるだけです。
scaleやpositionは作成したオブジェクトによるので適当に調整してください。
名刺をカメラで読み取るとミャクミャク様が出てきたので成功です。
※AR.jsの設定なのか分かりませんが、オブジェクトがチラチラしてより怖く可愛く表示されてしまいました。
※まだ調査する必要がありそうです。
ここまでで任意の画像を認識すると、任意のオブジェクトを表示することができました。
WebARにはまだ場所をトリガーにする「Location Based」や、マーカーをトリガーにする「Marker Based」があります。
また機会があれば、これらにも挑戦してみたいと思います。
