centroid3 static method

void centroid3(
  1. Coordinate p1,
  2. Coordinate p2,
  3. Coordinate p3,
  4. Coordinate c,
)

Computes three times the centroid of the triangle p1-p2-p3. The factor of 3 is left in to permit division to be avoided until later.

Implementation

static void centroid3(
    Coordinate p1, Coordinate p2, Coordinate p3, Coordinate c) {
  c.x = p1.x + p2.x + p3.x;
  c.y = p1.y + p2.y + p3.y;
  return;
}
