Fractal to img

Troubleshooting terramonkey
1

is there a simple way to save generated fractal to image? i want to look how i looks :slight_smile:
im generating fractal heighmaps, but i need them also in image format, for minimaps and etc

2

ImageRaster (in core) and/or ImagePainter (plugin available through the sdk).

ok, first i understand that i have to set every pixel of hte image manualy, is that correct?
second:
[java]public void test1() {
FractalSum fractal = new FractalSum();

	fractal.setRoughness(0.7f);
    fractal.setFrequency(1.0f);
    fractal.setAmplitude(1.1f);
    fractal.setLacunarity(2.12f);
    fractal.setOctaves(8);
    fractal.setScale(0.02125f);

	fractal.addModulator(new NoiseModulator() {

        @Override
        public float value(float... in) {
            return ShaderUtils.clamp(in[0] * 0.7f + 0.5f, 0, 1);
        }
    });

    FilteredBasis ground = new FilteredBasis(fractal);

    PerturbFilter perturb = new PerturbFilter();
    perturb.setMagnitude(0.319f);

    OptimizedErode therm = new OptimizedErode();
    therm.setRadius(5);
    therm.setTalus(0.061f);

    SmoothFilter smooth = new SmoothFilter();
    smooth.setRadius(10);
    smooth.setEffect(0.9f);

    IterativeFilter iterate = new IterativeFilter();
    iterate.addPreFilter(perturb);
    iterate.addPostFilter(smooth);
    iterate.setFilter(therm);
    iterate.setIterations(1);

    ground.addPreFilter(iterate);
    
    TerrainGrid terrain = new TerrainGrid("terrain", 33, 257, new FractalTileLoader(ground, 256f));
    
    
    float a[] = terrain.getHeightMap();
    int size = a.length;
    for (int i=0; i<size; i++) {
		System.out.println(a[i]);
	}
}[/java]

i create this fractal heightmap, but when trying to print height values i get 0.0, am i doing something wrong?

To set the image then yes. I’m not familiar with the fractal heighmap stuff tho so can’t help you there.
