SM1204 Semester A 2012

Due date 30 Oct

Collection via ACS

- Create your own drawing brushes (20%)
- Use of "if-else" or "for" structures (20%)
- Use of random or noise functions (20%)
- Apply to positions / colors / sizes of elements you draw

- With basic user interaction (20%)
- e.g. mousePressed, mouseX, mouseY

- Creative graphics (20%)

float d = dist(pmouseX, pmouseY, mouseX, mouseY);

noFill();

stroke(255);

for (inti=0; i<5; i++)

{

float s = (d+4)*(i+1);

ellipse(mouseX, mouseY, s, s);

}

fill(0, 10);

noStroke();

rect(0, 0, width, height);

if (mousePressed == true)

{

int r = mouseY / 15;

int c = mouseX / 15;

fill(255);

rect(c*15+1, r*15+1, 14, 14);

}

- dist(x1, y1, x2, y2)
- Calculates the distance between two points

- mouseX, mouseY
- the current coordinate of the mouse

- pmouseX, pmouseY
- The position of the mouse in the previous frame

- random(low, high)
- Generate random numbers (floating-point value) between low and high
