Hi, I want to split hexagon into triangles and get the coordinates for the each of treangle point. How i want to split hexagon, you can see in this picture.

I have class triangle and class point

C#

class Triangle
{
    public Point A { get; set; }
    public Point B { get; set; }
    public Point C { get; set; }
}

class Point
{
    public double x { get; set; }
    public double y { get; set; }
}

On the list of triangles i want to add each triangle (whith coordinates) which is in hexagon. Does anyone have any idea?

Thanks!

What do you mean by "does anyone"? This is a trivial problem, well too many people can solve it.
What have you tried so far?

Google for "C# Triangle Mesh algorithms" and you'll come up with all kinds of examples to do it.

If point(0) is at (x,y)
then it forms a triangle with points
(x,y) , (x, y+n) , (x + SQRT(n² - (n/2)²) , y + (n/2))

where n is the length of side of the triangle - which is N / 3 where N is the hexagon side length.

now you have the coordinates of triangle (0,1,5) every other triangle can be calculated trivially using simple addition.
