CS 1334 The University of Texas at Dallas Loopy Forests Lab Code

Question Description

I’m working on a javascript exercise and need support to help me study.

Lab Lesson #8 – Loopy For-ests

See Gitbook for supplemental content – using math formula to draw patterns:

https://kdoore.gitbook.io/cs1334/loops-using-math-…

my forest project: https://www.khanacademy.org/computer-programming/l…

1.Spin-off a copy of your forest project from Lab 4, where you wrote 2 functions:
Leaf ( x, y, leafAngle ) //x,y position, leafAngle of each leaf
Tree ( x, y ) //x,y position of each tree

2.Using the copied project, modify your code to generate:
at least 20 trees with at least 100 leaves on each ?tree

– Dont include more than one call to your tree function or leaf ?function in your code. (instead, use the for-loops to create multiple trees, multiple leaves on each tree)

– Use 2 for-loops to generate multiple copies of each object (1 loop for trees, 1 loop for leaves)

– Use one for-loop to call the Tree function ( 20+ times)

– Within the Tree function, use one ?for-loop to call the Leaf function ?(100+ times)

– See details of math function for Leaf x, y, input parameters below

– Use a constant or random value for the leafAngle parameter

– Do not use draw( ) function ?

3.Use random numbers: (a, b) and mathematical formulas to place the leaves on the trees

Generate two random numbers, with min, max as specified below:
- 0 <= a <= w [w is the size of tree or however big you want] ?
- 0 <= b <= 360 [ angle ]

Pick a math equation to generate a pattern,?below
Or, create your own pattern

Circle	x = a*sin(b)	y = a*cos(b)
Oval	x = a*sin(b)	y = 2acos(b)
Half-circle	x = a*sin(b/2+90)	y = a*cos(b/2+90)
Triangle	x = a*sin(b)	y = -a
Conifer	x = a*cos(b/2)	y = a*sin(b+90)
Crown	x = a*cos(b/2)	y = -abs(a*sin(b+90))
Butterfly	x = (2a/w)((b+45)%90- 45)*sin(b)	y = (2a/w)((b+45)%90- 45)*cos(b)

4. Save your code and submit following the lab submission instructions on e-learning
