const float * value_ptr() const
Returns a const pointer to the raw data array.

static const Point2 & Origin()
(0,0) - a shortcut for a special point that is frequently needed
+
Point2()
Default point at the origin.
+
static const Point2 & One()
(1,1) - a shortcut for a special point that is frequently needed
+
Point2(float *p)
Constructs a point given a pointer to x,y data.

+
bool operator!=(const Point2 &p) const
Check for "inequality", taking floating point imprecision into account.

float w() const
In homogeneous coordinates, the w coordinate for all points is 1.0.
