Processingで3次元空間上に文字をかくやり方

Last updated at Posted at 2019-09-03

#やりたいこと
3次元空間では視点を変えると、単にtext()で表示させているだけの文字も移動してしまう。デカルト座標に依存せずに画面に文字を固定表示させたい。

#実装方法

void showText3d(String str1) {
  pushMatrix();
  camera();
  hint(DISABLE_DEPTH_TEST);
  noLights();
  textMode(MODEL);
  text(str1, 20, 20);
  hint(ENABLE_DEPTH_TEST);
  popMatrix();
}

pushMatrix()とpopMatrix()の組み合わせで解決。
