How to do a circle with triangular mesh?

I'm planning to generate this image.

Thank you for your message. The file you gave shows an error result. Based on the image, it generates a quadrilateral mesh. I need to have a triangular mesh.

[KSSV]

Yes, it gives quadrilateral mesh. So you have the points (x,y) from this mesh. On these use delaunayTriangulation to get triangular mesh.

[loyyy]

I tried to run the codes but it shows error results. And, I don't know where to apply delaunay triangulation.

[KSSV]

What error you got when you try to run?

[loyyy]

I got an error result on each of the 3 scripts.

[KSSV]

Try:

MeshCircle([0 0],1,50,10) ;

[loyyy]

It resulted to this.

Is there another way of doing it, more easy? I think I will not able to explain the code properly to my mentor.

[Walter Roberson]

No, there is no easier way. Every available method requires that you understand how to pass parameters to a function. The [0,0] and so on that KSSV showed are not just decorative!

Thank you so much! I just saw this and your comment is extremely helpful.
