I have a polygon made of successive edges on a plane, and would like to subdivide it in sub-polygons being triangles or rectangles. Where can I find an algorithm to do this ? Thanks. Say, we want to split a 4-sided polygon into 4 sub-polygons. We start by splitting the polygon into two pieces one with area, and another one with area. The same process would then be repeated on the bigger sub-polygon till all sub-polygons are of target area. At each step of splitting into two sub-polygons, there are several possible edge pairs.

## Divide faces into triangles or quadrangles.

The polygon may be convex (but bonus points if you come up with an algorithm that works for concave shapes) The polygon has an arbitrary number of edges (3 or more) The amount of tessellation (preferably the number of vertices added by the algorithm) should be parametrized; The polygon's edges may be divided by the algorithm.This document contains approximately 10 questions related to the Virginia Standards of Learning 3.12 (define polygon; identify and name polygons with 10 or fewer sides; and combine and subdivide polygons with three or four sides and name the resulting polygon(s)).Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields.. Divide a 2D polygon with N vertices into triangles draw in a 3D space. Ask Question. Triangulating a planar 2D concave polygon in 3d space.

An example of concave polygon is shown below. Convex Polygon. If a polygon has no reflex angle, then it is said to be a convex polygon. Examples of the convex polygons are shown below. Regular Polygon. A regular polygon's sides are all of the same length and its angles are the same size. For example, a square is a regular polygon. Examples of.Click OK on the Parcel Division dialog box to subdivide the parcel using the method you have chosen. By proportional area. Specify the number of parts or parcels to create in the Number of parts text box. Parcels are proportioned into equal areas to subdivide the entire parcel. There is no remainder parcel. Question: MATLAB Question If The Polygon Is Concave, How Do You Know Whether The Polygon Can Be Broken Down Into Triangles Anyway? A Simple Concave Polygon Can Be Broken Down Into Triangle, When Non Of The Triangles Intersect. This Can Be Checked By Checking The Position Of A Vertex In Relation To The Position Of The Previous Vertex. A concave polygon, on the other hand, is a polygon with at least one angle that is pointed inwards. If you picture a rectangular brick colliding with a giant metal cone, the end result would be a. What are different types of polygons? (i) Convex polygon: It is a polygon in which all the inner angles are much less than. All the diagonals of the convex polygon lie inside the polygon. Observation: All the four angles of the above polygon are less than. (ii) Concave polygon: It is a polygon in which at least one of the inner angle is more.
