Function PointFromCoords

s2/point.go:52–57

PointFromCoords creates a new normalized point from coordinates. This always returns a valid point. If the given coordinates can not be normalized the origin point will be returned. This behavior is different from the C++ construction of a S2Point from coordinates (i.e. S2Point(x, y, z)) in that i

// This behavior is different from the C++ construction of a S2Point from coordinates
// (i.e. S2Point(x, y, z)) in that in C++ they do not Normalize.
func PointFromCoords(x, y, z float64) Point {
	if x == 0 && y == 0 && z == 0 {

	return Point{r3.Vector{X: x, Y: y, Z: z}.Normalize()}
}

// OriginPoint returns a unique "origin" on the sphere for operations that need a fixed
// reference point. In particular, this is the "point at infinity" used for
