# Example Code - Feb 19

```java
float minSize, maxSize;
float balancePoint;

void setup(){
  size( 600, 600);
  colorMode( HSB, 360, 100, 100,100);
  background(0);//only set one time
  minSize = 10;
  maxSize = 60;
  balancePoint = width/2;  //start at middle of canvas
}

void draw(){
  if(mousePressed){
    translate( mouseX, mouseY);//translate origin to mouse position
    //for( int angle = 0; angle< 360; angle += 45){
    // rotate( radians( angle));
     positivePattern( balancePoint, mouseX);
    //} //end for
    resetMatrix();
  } //end if-mousePressed
  
}//end of draw


//determine current size, color: gradients across the positive region
void positivePattern(  float balancePoint, int mX){
   
  color cPos1 = color( 230, 100, 100); //purple
  color cPos2 = color( 80, 100, 100); //lime
  
  //define curColor based on mX relative to balancePoint
  float fraction = map( mX, balancePoint, width, 0.0, 1.0);
  color curColor = lerpColor( cPos2, cPos1, fraction); //fraction varies beteween 0.0, 1.0
  
  float curSize = map( mX, balancePoint, width, minSize, maxSize );
  posRecursivePattern( curSize, curColor);
  
}

//Draws a single motif - nested size and color gradient

  shape(s1,0,0); //render the shape at the origin
  
  //recursive call

  //task - with reversed stacking - mirror across origin
  pushMatrix();
  scale( -1, -1);//mirror across the x, y axis (origin)
  shape( s1, 0, 0);
  popMatrix();
}

//Draws a single shape

  s.vertex( 0,0  ); //1 x, y points
  s.vertex(.5 * len , 0 ); //2
  s.vertex(len , .5* len ); //3
  s.vertex(.5 * len , len  );//4
  s.vertex( 0,  .5* len ); //5
  s.vertex( 0, 0 ); //6
  
  s.beginContour(); //make internal cutout 
  s.vertex( len*.25,len*.45); //inner cutouts - point 5
  s.vertex(len*.6, len*.6);  // 
  s.vertex( len*.45, len*.25); // 
  s.vertex(0,0);
  s.endContour(); //end internal cutout

  
  s.endShape();
  //shape( s, 0,0);  //render to the canvas
  return s; //return the PShape

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kdoore.gitbook.io/cs1335/project-1/plan-structure--functions/example-code-feb-19.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
