2. Review Curve Vertex
At least 4 points: Control point1, vertex 1, vertex 2, control point2
A smooth curve is drawn between vertext1 and vertex 2 based on the control points.

3. Function Function Definition Calling a function Parameters
Return type and return statement

4. Function: Intuitive Understanding
Function F
F(x) X

5. Examples
Add 10 20 10
X=10, y=4
Multiply (x,y) 40
Subtract 6 4

6. Function concept int z = add(34, 10); // function call
Function definition:
int add (int x , int y) // x,y formal parameters {
int sum;// sum is a local variable
sum = x + y;
return sum; }
add 34 10 X Y
sum

7. translate
Translate function moves the origin by the amount specified int x,y; x = 10; y = 10; void draw() { background(30,50,60); pushMatrix(); translate(x,y); rect(0,5,70,30); x++; if (x> width) x = 0; y++; if (y>height) y = 0; popMatrix(); }
