Hi all,
I’m pretty new to coding and I’m trying to convert a processing file to a p5.js file but it keeps giving me an error. I know there’s something wrong wrong about the PVector but not sure what.
Can somebody help me out?
This is the p5.js file now<<<<<
var points;
var d;
function setup() {
initializeFields();
createCanvas(600, 800);
for (var i = 0; i < points.length; i++) {
points[i] = new PVector(random(width), random(height), random(width));
}
}
function draw() {
loadPixels();
for (var x = 0; x < width; x++) {
for (var y = 0; y < height; y++) {
var distances = new Array(points.length);
for (var i = 0; i < points.length; i++) {
var v = points[i];
var z = frameCount % height;
var d = dist(x, y, z, v.x, v.y, v.z);
distances[i] = d;
}
var sorted = sort(distances);
var r = map(sorted[0], 10, 150, 0, 185);
var g = map(sorted[1], 220, 50, 255, 110);
var b = map(sorted[2], 0, 200, 255, 10);
var index = x + y * width;
pixels[index] = color(r, g, b);
}
}
updatePixels();
}
function initializeFields() {
points = new Array(100);
d = “hello”;
}
and this was the origin <<<<<
PVector points = new PVector[100];
String d = “hello”;
void setup() {
size(600, 800);
for (int i = 0; i < points.length; i++) {
points[i] = new PVector(random(width), random(height), random(width));
}
}
void draw() {
loadPixels();
for (int x = 0; x < width; x++) {
for (int y = 0; y < height; y++) {
float[] distances = new float[points.length];
for (int i = 0; i < points.length; i++) {
PVector v = points[i];
float z = frameCount % height;
float d = dist(x, y, z, v.x, v.y, v.z);
distances[i] = d;
}
float[] sorted = sort(distances);
float r = map(sorted[0], 10, 150, 0, 185);
float g = map(sorted[1], 220, 50, 255, 110);
float b = map(sorted[2], 0, 200, 255, 10);
int index = x + y * width;
pixels[index] = color(r, g, b);
}
}
updatePixels();
}
Many thanks!!
