手順

１：SATCH Studio Liteでダミー・トラッキングして２Ｄコンテンツの表示シナリオを作成

２：シナリオのトラッカーをtestFaceTrackingAutoinitのものと入れ替える

３：SATCH Studioのフルバージョンでシナリオを読んで、Luaコードを書き換える

SATCH Studioのフルバージョン版を起動して、シナリオを読み込みます。

シナリオがオリジナルと異なっているので、Scaleが変わっています。

Object Editorで「model2D_1」を選んで、Scale値を500位に設定して、Set initial valuesをクリック。



Luaコードを変更します。

元のままでは、２Ｄオブジェクトがお顔に追随してしまいます。今回は検出したら２Ｄオブジェクトを固定にしたままにします。

変更をかけるLuaはmainです。

Outlinerからmainというluascriptを右クリックで選んで、Open in Lua Editorを選択。

変数に以下のようなものを追加。

local current_pos = Vector3()
	local ini_count = 0
	local ini_x = 0
	local ini_y = 0
	local ini_z = 0

--main routine
