I just don’t get it…

I powered my way through the other flower/fractals levels, even as much to understand it enough to help explain it to someone else…

But I am just lost and frustrated at this point… any help/pointers would be welcome.

Code and screenshot below…

```
// Check the guide for the description of the problem
// Here are some functions to help draw the curves.
function degreesToRadians(degrees) {
// All vector operations require working in radians rather than degrees.
return Math.PI / 180 * degrees;
}
this.koch = function(start, end) {
// This function will draw a Koch Curve between two Vector positions
//this.say(String(end) + " " + String(start));
// Start by creating a vector from start to end using Vector.subtract.
var full = Vector.subtract(end, start);
// Use the magnitude of the vector to check for the stop condition.
var distance = full.magnitude();
if (distance < 4 ) {
// Move into position and draw the line, don't forget to toggle flowers properly.
this.toggleFlowers(false);
this.moveXY(start.x, start.y);
this.toggleFlowers(true);
this.moveXY(end.x, end.y);
return;
}
// Need to draw 4 shorter Koch curves with sides 1/3 the length.
// We will calculate the 3 intermediate points, A, B, & C.
// We just need the point that is one-third of the full Vector from the start Vector.
var third = Vector.multiply(full, 1 / 3);
var A = Vector.add(start, third);
// This one needs to be rotated 60 degrees from A but the same length. Use rotate and add to get B.
var rotate = Vector.rotate(third, degreesToRadians(60));
//rotate = Vector.multiply(rotate, 1);
var B = Vector.add(rotate, A);
// This point works out to adding another third to A.
// ?? Do what ??
//B = Vector.add(third, A);
// Now we can draw the 4 curves connecting start, A, B, C, and end.
this.koch(start, A);
this.koch(A, B);
this.koch(B, A);
this.koch(A, end);
};
var whiteXs = [new Vector(6, 6), new Vector(74, 6), new Vector(74, 61), new Vector(6, 61)];
this.setFlowerColor("blue");
this.koch(whiteXs[0],whiteXs[1]);
this.koch(whiteXs[1],whiteXs[2]);
this.koch(whiteXs[2],whiteXs[3]);
this.koch(whiteXs[3],whiteXs[0]);
