Basic Data Organization: There are several different layers of data should be clear here: 1. geom: they are the basic units, includes: vec2(point), rect, circle, curve, edge, and polygon polytree and so on, apparently the rect includs to points and could be transferred to 4 edges, each edge needs to points, circle needs a center(point) and a radius, polygon and polytree includs a list of edges, curves, points, or even some holes 2. controller: this level includs the segment, arc, corner and area. segment is corresponding to an geom edge but also needs two corners, arc is corresponding to an curve and so on, corner is just a point, but also it includs all the segments or arcs connected to it. so the level is like a mutua-link relationship, you could find all the data you need. Such as all the corners in an edge, all the arcs in a corner. Area includs all the data above. All these four parts has a unique ID, easy to tell and trace. 3. Segment, arc and corner are all kinds of an Elements.

Setup: Just download the whole package and open the index.html

Usage: Follow the UI and button to drag and point on the canvas to create your area, and adjust their position Draw the circle, rect, and use the line to draw any shape you like, the splitter will split them into each un-overlapped area.

Code: The code is not that hard to understand: All the code has perfect name to explain it self. And the above file structure also explains the file or the class's meaning.

Q&A: just contact me by QQ or wechar or by phone.
