Question is off-topic or not relevant

# Three Vector3 points, find circle

Hope someone can help me! I have three Vector3 points, and I want to find the circle, which goes through all points

Cheers

This is not a Unity Question. If you Google "circle passing through three points," you will find a zillion hits walking through the math.

Given point A B C, most of the approaches boil do to finding the intersection of the perpendicular bisector of line segments AB and BC. Rather than implement the formulas described in most questions, you can do this calculation 'literally'. The Unity Wiki Mathf3D class contains code for finding line/line intersection. A solution in 3D will depend on the three points being co-planer.
