WebARサンプルの表示オブジェクトを変更してみた

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。

表示されるキャラクターのオブジェクトを作ります

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。

WebARみゃくみゃく様

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。

※参考ツイート

任意の3Dオブジェクトを表示させる

前回のサンプルソースを修正します。

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。
scaleposition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。

試してみよう

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。

名刺ARみゃくみゃく様

※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。

結果

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。
