Hello!

I have a problem with terrain generation: I want to make terrain smooth as it is in some mods like RTG or BiomeBundle, for example:

So I have succesfully implemented Open Simplex Noise and... terrain changed: now it looks smoother but there are sharp mountains, only minecraft "flying terrain" is eliminated. And also its super flat in some places.

Here's my code:

private double useNoises(int chunkX, int chunkY, int chunkZ, double coordinateScale, double heightScale, double depthSize, double unk1, Biome b) {
    double d0 = 0.0D;
    double d1 = 0.0D;
    double noiseY = 0.0D;
    double modifier = 1D;


    for (int i = 0; i < 16; ++i) {
        double d4 = SimplexOctavesGenerator.maintainPrecision((double) chunkX * coordinateScale * modifier);
        double d5 = SimplexOctavesGenerator.maintainPrecision((double) chunkY * heightScale * modifier);
        double d6 = SimplexOctavesGenerator.maintainPrecision((double) chunkZ * coordinateScale * modifier);
        d0 += this.openSimplex.eval(d4, d5, d6) * modifier;
        d1 += this.openSimplex.eval(d4, d5, d6) * modifier;
        noiseY += this.openSimplex.eval(SimplexOctavesGenerator.maintainPrecision((double) chunkX * depthSize), SimplexOctavesGenerator.maintainPrecision((double) chunkY * unk1), SimplexOctavesGenerator.maintainPrecision((double) chunkZ * depthSize)) * modifier;

        if (i < 8) {
        }

        modifier /= 8.0D;

    }

    double lowerLimitScale = 512.0D;
    double upperLimitScale = 512.0D;
    double slide = 1D;

    double result = MathHelper.clampedLerp(d0 / lowerLimitScale, d1 / upperLimitScale, (noiseY) * slide);


    return result;

}

Original code is in net.minecraft.world.gen.NoiseChunkGenerator:71 called func_222552_a

 

And also another question is what is an equivalent of "heighVariation" in 1.12.2? In 1.14 there is only a depth variable, but I want to make terrain more bellied or something in some biomes.

 

Thanks for help. I really need this terrain!

 

 

You could manually apply bilinear interpolation to the terrain to smoothen out sharp mountains.

Thanks for quick reply.

So how to implement it to Minecraft? Have you any code to make it or any tutorial?

Thanks

Basically the concept is to make blocks between sharp chunks take a medium value between the two sharp chunk height.

Check out https://en.wikipedia.org/wiki/Bilinear_interpolation.

There is also this example in applying bilinear interpolation to images https://rosettacode.org/wiki/Bilinear_interpolation.

Okay, I will try to do something but should I use 2D noise or 3D noise?

And why "scale" value in BiomeBuilder not works?

Spoiler

public final class WNDuneSea extends WNBiome {
    public WNDuneSea() {
        super("dune_sea",(new WNBiomeBuilder()).surfaceBuilder(SurfaceBuilder.DEFAULT, SurfaceBuilder.SAND_SAND_GRAVEL_CONFIG).precipitation(Biome.RainType.NONE).category(Biome.Category.DESERT).depth(2.6F).scale(6F).temperature(2.0F).downfall(0.0F).waterColor(4159204).waterFogColor(329011).parent((String)null));

There is depth 2.6F and scale 6F and the terrain is flat, not hilly
