At first remove last point of test to convert your polygon to polyline, then balance your tolerance. If your points are cordinate on the earth, 1 means at least 50 mi (80 km)!!! Try 0.001 for tolerance

How to convert a big 1D array into series of small key:pair objects in JS?

Asked 2018-Jun-20 at 06:30

I am trying to make free hand drawing sketchpad in threeJS. Most of the part has been done and able to draw the shapes. Now my next step is to use the simplify-JS for simplifying the points in my polygon. The concern is that I am passing my array as buffer geometry and using Line Mesh to draw on screen. I am creating array like [x,y,z,x,y,z,x,y,z... and so on] till MAX_POINTS which is 10000 in my case. Example

You can use a simple for loop to traverse the array and push objects in a new array.

QUESTION

Polyline simplification

Asked 2018-Apr-08 at 20:24

I am trying to understand this code.

What I understand is that the code tries to refine the geometry based on a tolerance. Basically it checks if the distance between two points is less than the tolerance or not, and retains/removes the points accordingly.

I have a query though. Points are in lat-long format. The code simply calculates a square of the Euclidean distance(simple square formula we all know). Isn't this a wrong approach as lat-long based distance is different from Euclidean distance?

Second, what is the unit of tolerance? In this test, the tolerance value of 5 is used. How does this value fit in here?

Yes, that's a first step, in the second step it tries to find consecutive lines that are (basically) in line and merges them.
