I’ve got a arbitrary collection of 3d points, i know they’re coplanar, but how do i calculate that plane?
Take any three distinct points, and form a triangle of non-zero area. Compute the cross product of two of the triangle’s sides. That gives you the plane’s normal, and you can use the common point as a point on the plane.
A point on a plane plus a normal defines a plane.
