I am trying to find the equations to calculate:
- The intersection surface area generated by the intersection of 3 circles (3 circles
like a Venn Diagram).
- The 3 circle's radius could be be different one from others but always 0 < radius <= 1
- The circles centres positions are fix and they are separated by 1 unit each from other (the circle's centres are located in the vertexs of an equilateral triangle of side=1)
To be clearer... the intersection "of the 3 circles" area will result in a figure like an "irregular Reuleux triangle". That means a Reauleaux triangle where the internal triangle could be any (and not only an equilateral triangle) and the three radius could be different one from the others
Thanks a lot in advance
