Write a three.js/HTML programming to generate a Sierpenski Triangle using recursion (generate until 10 depth of recursion)

Need the index code with it too so I am able to run it

INDEX CODE:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>My first three.js app</title>
<style>
body { margin: 0; }
canvas { display: block; }
</style>
</head>
<body>
<script src="js/three.js"></script>
<script>
// Our Javascript will go here.
</script>
</body>
</html>

TRIANGLE CODE:

import turtle

def drawTriangle(points,color,myTurtle):
myTurtle.fillcolor(color)
myTurtle.up()
myTurtle.goto(points[0][0],points[0][1])
myTurtle.down()
myTurtle.begin_fill()
myTurtle.goto(points[1][0],points[1][1])
myTurtle.goto(points[2][0],points[2][1])
myTurtle.goto(points[0][0],points[0][1])
myTurtle.end_fill()

def getMid(p1,p2):
return ( (p1[0]+p2[0]) / 2, (p1[1] + p2[1]) / 2)

def sierpinski(points,degree,myTurtle):
colormap = ['blue','red','green','white','yellow',
'violet','orange']
drawTriangle(points,colormap[degree],myTurtle)
if degree > 0:
sierpinski([points[0],
getMid(points[0], points[1]),
getMid(points[0], points[2])],
degree-1, myTurtle)
sierpinski([points[1],
getMid(points[0], points[1]),
getMid(points[1], points[2])],
degree-1, myTurtle)
sierpinski([points[2],
getMid(points[2], points[1]),
getMid(points[0], points[2])],
degree-1, myTurtle)

def main():
myTurtle = turtle.Turtle()
myWin = turtle.Screen()
myPoints = [[-100,-50],[0,100],[100,-50]]
sierpinski(myPoints,3,myTurtle)
myWin.exitonclick()

main()

In this programming assignment, you will write C code that performs recursion. For the purpose of this assignment, you will keep all functions in a single source file main.c. Your main job is to write a recursive function that generates and prints all possible password combinations using characters in an array. In your main() function you will first parse the command line arguments. You can assume that the arguments will always be provided in the correct format. Remember that the...

Can you please solve this using recursion/ dynamic programming? Any programming language is fine. Wallace the Weightlifting Walrus is training for a contest where it will have to lift 1000 kg. Wallace has some weight plates lying around, possibly of different weights, and its goal is to add some of the plates to a bar so that it can train with a weight as close as possible to 1000 kg. In case there exist two such numbers which are equally...

a) Using the programming tool of your choice generate 10 random numbers from a flat distribution between -0.5 and 0.5, and find the mean of these 10 numbers. Consider this mean to be the ‘result’ of this procedure. b) Repeat this 10 times and calculate the mean and variance of your 10 results. Is the distance of the mean from 0 about what you would expect? Why? c) Now repeat it 100 times and calculate the mean and variance. Is...

Purpose For this programming project, you will create an application that draws fractal-like shapes using recursion. The class that creates the graphics window for the display of the shapes is given to you (see below). What you have to do is create a set of classes for the three shapes that are displayed in the graphics window. Two of the shapes must be a Sierpinski triangle and an H-shape. The third shape is your choice, though it must be a...

Write the class RecursiveProbs, with the methods listed below. Write all the methods using recursion, not loops. You may use JDK String methods like substring() and length(), but do not use the JDK methods to avoid coding the algorithms assigned. For example, don't use String.reverse(). public boolean recursiveContains(char c, String s) returns true if the String contains the char, otherwise returns false. Here is the code for this method, which you should use as an example to see how to...
