I’m studying the code below (written by S. Calderon) and we’ve been asked to turn the generated image from 2D to 3D. The code itself is quite complex and as a beginner, I’d appreciate any hints on how I can go about this task??? Any tips on how I get started with this assignment would really be appreciated.

```
/*
Task: Explore objects and classes by experimenting with object-based graphics that
allow for different instances of the same object within the script. Next, try to translate
the geometry into 3-dimensional space.
*/
//VARIABLES
int branchMax = 3;
int extentMax = 5;
//SETUP
void setup()
{
size(800, 400);
smooth();
noLoop();
strokeWeight(1);
}
//DRAW
void draw()
{
background(255);
Vector node = new Vector(width/2, height, random(20,50), 270);
fractalise(node, extentMax);
}
void mousePressed()
{
draw();
}
void fractalise(Vector v, int extent) //the recursive function for tree growth
{
if(extent <= 0 ) //exit condition is when number of extensions less than or equal to zero
{
return;
}
extent--; //decrements value of the integer variable by one
v.Render();
for(int i=0; i<branchMax;i++)
{
Vector vGrowth = new Vector(v.getEndPointX(), v.getEndPointY(), //creates new vector
random(50,100), random(180, 360)); //angle of growth is random within set parameters
vGrowth.Render(); //renderise and fractalise recursive
fractalise(vGrowth, extent);
}
}
class Vector //name of class declared
{
float x, y, r, theta; //co-ordinates for the class Vector
float EndX, EndY; //breadth of the class Vector
Vector (float _x, float _y, float _r, float _theta)
{
this.x = _x;
this.y = _y;
this.r = _r;
this.theta = radians(_theta);
EndX = getEndPointX();
EndY = getEndPointY();
}
float getEndPointX() {
return (x + r*cos(theta)); //returns x-coordinate in polar form
}
float getEndPointY() {
return (y + r*sin(theta)); //returns y-coordinate in polar form
}
void Render() //function dictates branch color and line length
{
stroke(random(200), random(200), random(200)); //lines of the tree are random colors
line(x,y, getEndPointX(), getEndPointY() );
noFill();
ellipse(x,y, 5, 5);
}
}
