示例1: update

// Use either ofNoise() in case you want to use oF internal Perlin Noise
// or per.noise() in case you want to use Chris Little's implementation
//Comment or Uncomment depending on your needs
// Option 1a, Chris direct ::::
//Perlin per;
//noiseFloat = per.noise(pos.x * 0.0025, pos.y * 0.0025, glob.getElapsedFrames() * 0.001);
// Option 1b, Chris via Globals.h ::::
noiseFloat = glob.getPerlinNoise(pos.x * 0.0025, pos.y * 0.0025, glob.getElapsedFrames() * 0.001);
// Option 2, openFrameworks internal ::::
