C++ (Cpp) interpolatedNoise2D Examples

Example #1

File: perlinNoise.cpp Project: ghosthamlet/vim3d

float perlinNoise::perlinNoise2D(float x, float y){
		
	float freq = frequency;
	float amp = amplitude;
	float total = 0.0f;
	int n = numberOfOctaves;
	
	for(int i=0;i<n;i++){
		if (freqOctDep) freq *=2;
		if(ampOctDep) amp*=persistence;
		total = total + interpolatedNoise2D(x * freq, y * freq) * amp;
	}
	
	return total;
}

Example #2

File: NoiseGenerator.hpp Project: veldrinlab/researchEngine

	T perlinNoise2D(const int x, const int y)
	{	
		T value = 0.0;
		T p = persistance;
		int n = octaveAmount;
		T freq = frequency;
		T ampl = amplitude;		
		T z = zoom;

		for(int i = 0; i < n; ++i)
		{
			value += interpolatedNoise2D(x * freq/z, y * freq/z) * ampl;
			ampl *= p;
			freq *= 2.0;
		}

		return value;
	}
