Pine Tree Generator

The author is Richard Qian Li, 2023 version 0.0.1

Usage

Import the modules you need

import * as THREE from "three";
import PineTree from "./Pine";

if you need to test its property settings, You may use the dat.gui, you can import it like this, and use it like this:

import * as dat from "lil-gui";

const global = {
  message: "twitter@urban_banal                    ",
  expansion: 0.95,
  slenderness: 50,
  trunkRatio: 0.2,
  leafThreshold: 0.2,
  leafSize: 20,
  height: 50,
  spawningStength: 1,
  leafBlobPropotion: 0.3,
  leafOpacity: 0.4,
  x: 0,
  z: 0,
  leafColor: "#558822",
  curve: true,
  regenerate: regenerate,
  saveImage: function () {
    captureImage = true;
  },
  saveModel: function () {
    if (pine) pine.exportToOBJ();
  },
};

const gui = new dat.GUI();
gui.add(global, "message").name("Author: Richard Qian Li, 2023");
gui.add(global, "expansion", 0.15, 0.95, 0.05);
gui.add(global, "slenderness", 5, 100, 5);
gui.add(global, "trunkRatio", 0.1, 1, 0.1);
gui.add(global, "spawningStength", 0.1, 1.2, 0.1);
gui.add(global, "leafBlobPropotion", 0.1, 2, 0.1);
gui.add(global, "leafThreshold", 0.05, 1, 0.05);
gui.add(global, "leafSize", 0, 100, 10).onChange(() => {
  if (pine) pine.leafSize = global.leafSize;
});
gui.add(global, "leafOpacity", 0, 1, 0.1).onChange(() => {
  if (pine) pine.leafOpacity = global.leafOpacity;
});
gui.add(global, "height", 1, 100, 1).onChange(regenerate);
gui.add(global, "x", -100, 100, 1).onChange(() => {
  if (pine) pine.treeGroup.position.x = global.x;
});
gui.add(global, "z", -100, 100, 1).onChange(() => {
  if (pine) pine.treeGroup.position.z = global.z;
});
gui.add(global, "curve").onChange(() => {
  if (pine) pine.curve = global.curve;
});
gui.addColor(global, "leafColor").onChange(() => {
  if (pine) pine.leafColor = global.leafColor;
});
gui.add(global, "regenerate");
gui.add(global, "saveImage");
gui.add(global, "saveModel");

the constructor of the pine tree is like this:

let pine = new PineTree(
  height,
  x,
  z,
  expansion,
  slenderness,
  trunkRatio,
  leafThreshold,
  spawningStength,
  leafBlobPropotion,
  leafSize,
  curve,
  leafColor,
  leafOpacity
);
