Shuffled Camera Feed Puzzle(翻訳済み)


ライブカメラでScatter widgetを使用しデモしています。カメラフィードを構成するシャッフルされた長方形のグリッドが表示されます。 グリッドをダブルクリックすることを繰り返して張り替えるか、四角形をドラッグすることでカメラフィードを元にもどせます。

Shuffled Camera Feed Puzzle

This demonstrates using Scatter widgets with a live camera.
You should see a shuffled grid of rectangles that make up the
camera feed. You can drag the squares around to see the
unscrambled camera feed or double click to scramble the grid
