Hello world !
I’m a noob in procedural generation and i’m trying to make an infinit terrain like Minecraft. I use a noise fonction, but when I generate a chunk, the next chunk… It seems to be a chaotic terrain ! The noise isn’t continous. We can see easily the border of each chunk.
I despair… Can you help me ? This is my noise function :
[java]
public void init_noise3D(int seed){
random = new Random(seed);
for(int i = 0; i < xsize; i++){
for(int j = 0; j < ysize; j++){
for(int k = 0; k < zsize; k++){
noiseTab3D1[i][j][k] = (float)random.nextDouble();
}
}
}
}
public float random_noise3D(int i, int j, int k)
{
return noiseTab3D[i][j][k]*10;
}
public static double interpolation_lineaire1D(double a, double b, double x) {
return a * (1 - x) + b * x;
}
public static double interpolation_cos1D(double a, double b, double x) {
double k = (1 - Math.cos(x * Math.PI)) / 2;
return interpolation_lineaire1D(a, b, k);
}
public double interpolation_cos3D(double a, double b, double c, double d, double e, double f, double g, double h, double x, double y, double z) {
// TODO Auto-generated method stub
double i1 = interpolation_cos1D(a, b, x);
double i2 = interpolation_cos1D(c, d, x);
double i3 = interpolation_cos1D(i1, i2, y);
double i4 = interpolation_cos1D(e, f, x);
double i5 = interpolation_cos1D(g, h, x);
double i6 = interpolation_cos1D(i4, i5, y);
return interpolation_cos1D(i3, i6, z);
}
public double function_noise3D(double x, double y, double z) {
int i = (int) (x / pas);
int j = (int) (y / pas);
int k = (int) (z / pas);
return interpolation_lineaire3D(random_noise3D(i, j, k), random_noise3D(i + 1, j, k), random_noise3D(i, j + 1, k), random_noise3D(i + 1, j + 1, k), random_noise3D(i, j, k+1), random_noise3D(i + 1, j, k+1), random_noise3D(i, j+1, k+1), random_noise3D(i+1, j+1, k+1), (x / pas) % 1, (y / pas) % 1, (z / pas) % 1);
}
[/java]
Thank you;
