Wave Figures
Sine, cosine and tangent waves can be used in combination with for-loops to create highly interesting visuals. A certain expression of these figures are the so-called “Lissajours curves”. For this purpose, two different waves are generated, each influencing the x- and y-position of several elements.
Assignment
Develop 5 different wave figures as animations in .mp4 format.
Get started with this template
void setup(){
size(900,900);
}
void draw(){
background(0);
translate(width/2,height/2);
// The amount of elements
float amount = 36;
// The size of the figure
float magnitude = 400;
fill(255);
noStroke();
for(int i = 0; i < amount; i++){
// wave1 alters the x-axis
float wave1 = sin(radians(frameCount + i * 10)) * magnitude;
// wave2 alters the y-axis
float wave2 = cos(radians(frameCount + i * 10)) * magnitude;
ellipse(wave1,wave2,10,10);
}
