QUESTION
I would really appreciate it if someone can help me with the code below. I am trying to plot Voronoi cells for some random data points and I want to assign some colours. The to reproduce my work is provided below. As you can see in the plot, there are thick lines. I completely want to eliminate those lines. Is there any way to get rid of them? I want to fill the polygon but not have the line. Any recommendation is greatly appreciated.
I took most of the code from here
...ANSWER
Answered 2022-Mar-09 at 04:05You can pass linewidth=0
to plt.fill()
to get rid of the lines.
QUESTION
I've build a graph with networkx, that looks like this: Graph
I want to fill every singel cell with a specified color. The Graph was drawn by nx.draw_networkx_edges() (returns a LineCollection). I found a similar question here (Fill area between lines), but the solution in the comments, doesn't worked for me.
I've also used plt.fill_between with a simpler graph and manually set the values:

QUESTION
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:
How to do such thing in opencv?
...ANSWER
Answered 2020-May-18 at 06:52In 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:
