QUESTION

Efficient methods of modifying a Delaunay triangulation

Asked 2020-Dec-07 at 15:53

MATLAB states on their website:

It is more efficient to edit a delaunayTriangulation to make minor modifications as opposed to recreating a new delaunayTriangulation from scratch

Are there any algorithms for this?

If I have 1000 points and move 3 of them to new locations, would the best method be to remove them and reinsert them, or is there a better way?

Yes. You can. For example, you can find an algorithm in this article (Dynamic Voronoi Diagrams) to update a given Delaunay triangulation (DT) in O(n) for each deletion or insertion. As the time complexity of constructing a DT is in O(n log(n)), absolutely updating the current DT is much faster in terms of the order of magnitude.

QUESTION

Set maximum length for generating Delaunay graph in R

Asked 2020-Jul-30 at 02:15

I was trying to generate Delaunay triangulation in R using the spatstat function 'delaunay'. However, I checked the documentation and seems there is no argument to set the maximum length. I noticed this post: How to set maximum length of triangle side in Delaunay triangulation in R? This seems done the same thing as I want, but as my point pattern is large so that I would prefer a simple and quick solution. Thank you!

Here is my code:

The Delaunay triangulation is a mathematically defined triangulation that does not involve the concept of a maximum segment length. If you want to constrain the maximum length of the segments in the triangulation, then it's not a Delaunay triangulation any more, and the algorithm for computing the Delaunay triangulation is not applicable.

You will have to specify what you want to happen when you impose a limit on the segment length. Should the algorithm just delete the edges which are too long? Delete the triangles that have an edge which is too long? If you delete stuff then the result is no longer a triangulation of the original points. Do you want to produce a different triangulation?

If X is your point pattern, then

how to apply a three point triangle gradient in opencv?

Asked 2020-May-18 at 06:52

Say we have a Delaunay-triangulation like this one:

produced from fillConvexPoly on getVoronoiFacetList

Inside there are triangles that can be obtained via getTriangleList. I want to draw Delaunay-triangulation like it is a smooth gradient image composed of triangles like this:

In OpenCV, I do not believe that there is any readily available function to do that. You would have to loop over each pixel in the image and compute the barycentric (area) interpolation. See for example, https://codeplea.com/triangular-interpolation

However, in Python/Wand (based upon ImageMagick), you can do it as follows:
