Concept

I looked throught some of the old computerarts provided and some of the organized and innerric graphs reminded me of the golden curve and the related math arts that I have seen. I remembered that the seeds of the sunflower followed a certain mathematical pattern and decided to use that as the model for my computer art.

I did use AI in this assignment to understand the pattern and mathematical logic the sunflower seeds followed, and to figure out some basic formulas that would allow me to recreate such shapes, but the codes were my own.

Code chunk

for (let pointn = 0; c * sqrt(pointn) <= 150; pointn++) {
    let angle = pointn * 137.5;
    let x = c * sqrt(pointn) * cos(angle);
    let y = c * sqrt(pointn) * sin(angle);
    
    //The code can be played with using many math functions, I tried some and attached them below
    
    //without sqrt
    //let x = (c * (pointn)/10) * cos(angle);
    //let y = (c * (pointn)/10) * sin(angle);

    // logarith(also looks good when made 1*c)
    // let x =5*c * log(pointn) * cos(angle);
    // let y =5*c * log(pointn) * sin(angle);

    //1/log
    // let x =100*c * 1/log(pointn) * cos(angle);
    // let y =100*c * 1/log(pointn) * sin(angle);

    let r = map(x, -300, 300, 80, 255);
    let g = map(y, -300, 300, 80, 255);
    noStroke()
    fill(r, g, (r + g) / 1.65);
    circle(x, y, 3);

The full code is relatively short so I picked the for loop section because I think it shows exactly what loops are helpful for. This chunk of code greatly utalizes the efficency of loops. It would be extremely difficult and time consuming to draw all the dots with accurate spacing by repeated lines of code. The for loop allows drawing and editing of the dots in one line, making it much easier. I also thouht it is intereating that I am able to create different patterns using only change in the mathematical function and slight adjustment to numbers, so I included those modified codes as well.

I was able to recreate the sunflower pattern in resting first, but I thought it looked a bit dull. Because it was a round pattern and included curves, I decided to make it rotate around the center to have a bit of a dillusional effect. I looked up a video tutorial on youtube and learned how to move start point to the center of the canvas and how to rotate it. The effect is pretty good.

Reflection

Drawing a mathematical pattern probably does not really fit the requirement of doing computer art, but I believe the Fibonacci numbers and its related curves do all look quite artistic, and the massive amount of dots needed is an excellent medium for praticing loops. My finished work seems a bit easy and a bit short for an assignment, and I might decide to try something more complicated and in accordance with class difficulties in future assignments.

Another thing is that AI really is quite helpful in the case of understanding scientific or math related concepts. I wouldn’t have been able to figure out all the formulas myself. I will attach my conversation with Gemini in the reference section

I started the work with directly showing my visible form with basic shapes. I did have to look up a new function “curve” to draw my bangs because the shape the “arc” function formed was not good enough. I drew the edge with the “curve” function and then filled in with the arc.

When it comes to portraying myself I thought of including my identity of being a science student apart from my looks, because I love what I do and it is a big part of me and I love to play with the sterotypes. At first I tried to do that by showing myself in a lab coat, but it was sort of difficult because I honestly didn’t know how to draw a lab coat, and I gave up to make a T-shirt looking thing. Then I included the “blowing things up” interation (which might be a bit inappropriate) because of how we used to joke about such things in lab courses.

I got the idea of eye tracing from the “Embarrassed Koala” example and Self-portrait by Pauline Wee that we were shown in class. But because I had the idea of making the explotion animation already, I thout it would be funnier if I made the eyes go in different dirrections and looked stupid, so I flipped through the p5js tutorials and founs the “variables and change” page which I then based my code on (I tried to look at the codes for the embarrased koala example but something was wrong with by browser and the code couldn’t show up). However what I intended to do was somehow different from the original code so I tried a few things and switched things around until the animation worked.

I like the eye tracking and the mouse click interaction codes so I put them below.

//eye movement
  lefteyeX=170+mouseX%width/26
  lefteyeY=150+mouseY%width/24
  righteyeX=230+(-mouseX)%width/26
  righteyeY=166+(-mouseY)%width/23
  //these codes are for normal (non-stupid) eye tracing
  // righteyeX=213+mouseX%width/26
  // righteyeY=150+mouseY%width/23

These are the codes for the eye tracking. I used -mouseX and -mouseY for the right eye so the direction of movement was oppodite from the left (I just instinctively tried this and found that it works so this likely isn’t the most concise code). It looked fun. I also kept the normal eye-tracking codes just in case I wanted to change into a normal look.

if(mouseIsPressed===true) {
    fill('orange')
    stroke('rgb(254,254,0)')
    strokeWeight(3)
  } else {
   noFill()
    noStroke()
    }
    triangle(170,300,160,276,180,292);
    triangle(179,291,185,271,197,290)
    triangle(197,290,232,278,226,298)
    triangle(179,300,157,317,187,312)
    triangle(179,307,182,338,198,312)
    triangle(197,290,206,263,211,293)
    triangle(198,312,207,328,214,304)
    triangle(214,311,232,324,225,300)
    triangle(225,292,241,295,224,306)
    noStroke()
    ellipse(200,300,57,32)
if(mouseIsPressed===true) {
    textSize(25)
    fill('rgb(197,0,0)')
    stroke('rgb(0,0,0)')
    strokeWeight(4)
  } else {
   noFill()
    noStroke()
    }
    text('BOOM!',164,308);

This is the code for the explosion animation on click. The explosion cloud was sort of bad because I couldn’t really figure out how to draw the fancy anime explosions, so it was just composed of an oval and a bunch of triangles. I learned the “if” “else” code from the Conditionals and Interactivity page of the p5js tutorial.

The final results look like this. My friends and I had a good laugh at it.

The space for future improvement that remains is that a lot of my codes are lengthy and verbose. I think this will be improved as I learn mode codes that will be able to show the same effects in a more consice and controlable way. I should also have researched more on the p5js page to perfect the codes I alread know but I was sort of exhausted by figuring out the curves and animations. And I think I lack some creativity in the thinking process as it took me quite some time to think of doing something other than regular portraying. Maybe spending some time brainstorming before I start assignments would help.

Overall I am relatively satisfied with the outcomes and really did enjoy playing around with codes and animations. And I am looking forward to more interesting activities 🙂
