Hi, I’m wondering if there is a way to increase the magnitude of noise at specific coordinates. The code below allows me to create topography based on perlin noise. As one can see, I get a noise value for every i and j. I’d like to know if it’s possible to have the noise value of a specific i, j to be magnified by a factor of 2 for example. Thank you for any input.
final static int W = 512; // width of the map
final static int H = 512; // height of the map
final static float k = 0.002; // noise coefficient
final static float l = 30; // resolution
float[][] m; // height map
boolean topomap = false;
void setup() { // creating perlin noise within window
size(512, 512);
m = new float[W][H];
for (int j=0; j<H; j++) {
for (int i=0; i<W; i++) {
m[i][j] = noise((W+i)*k,(H+j)*k);
}
}
}
void draw() { // drawing pixels
loadPixels();
for (int j=0; j<H; j++) {
for (int i=0; i<W; i++) {
if (!topomap) {
pixels[W*j+i] = color(round(m[i][j]*l)*(255/l)); // show height with "l" resolution
}
}
}
updatePixels();
}
