generate Delaunay triangle mesh

edit

this does not look like a delauny triangulation, more like a regular triangle-grid, deformed with some crude heightfield

This is not a delaunay. I want to know if it is possible doing something similar in opencv. This one was made using the trimesh module.

sure, there is Subdiv2D . (but again, to produce something like above, you would not need it)

I look into Subdiv2D . I'm not sure how it could be controlled the "mesh size". It is need a set of points. Do I need yo use findnonzero at the first image?

What is your advice @berak ?

with Subdiv2d , you start with the boundingrect. then you consecutively add points(e.g. landmarks), and each point will split an existing triangle

@berak do you mean something like that? http://pastebin.com/0XMqH0zC

however you're right. I need triangles (because I want to create a FEM model) I don't want pure delaunay. Is the process the same?

what on earth are you trying to achieve ?

@berak I'm sorry to bother you with lamme questions. I want to achieve something like this: http://www.learnopencv.com/delaunay-t... But I don't know how. I just want to create 2D mesh with triangles. Then using this 2D mesh as mask to apply on different images and create FEM model. But at this stage, I just want a 2D triangle mesh on this image. This picture has holes (stronger lines)

Looking at the example on the website, I don't know how I can create something similiar to the points.txt ,

didn't you mention, you had a list of points, the other day ? just insert them, one after the other.
