no formula. We have just two points and need the points among these.

Dear all,
Given that the coordinates of 4 points such as c1(x1,y1), c2(x2,y2), c3(x3,y3), c4(x4,y4).
Does any body know how to use plain sql / plsql to determine coordinates of a point e.g. (x,y) is within 4 points above efficiently. The 4 points supposedly form a rectangle rectangular.

calc_spline
calc_spline(3alleg4) Allegro manual calc_spline(3alleg4)
NAME
calc_spline - Calculates a series of values along a Bezier spline. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void calc_spline(const int points[8], int npts, int *x, int *y);
DESCRIPTION
Calculates a series of npts values along a Bezier spline, storing them in the output x and y arrays. The Bezier curve is specified by the
four x/y control points in the points array: points[0] and points[1] contain the coordinates of the first control point, points[2] and
points[3] are the second point, etc. Control points 0 and 3 are the ends of the spline, and points 1 and 2 are guides. The curve probably
won't pass through points 1 and 2, but they affect the shape of the curve between points 0 and 3 (the lines p0-p1 and p2-p3 are tangents to
the spline). The easiest way to think of it is that the curve starts at p0, heading in the direction of p1, but curves round so that it
arrives at p3 from the direction of p2. In addition to their role as graphics primitives, spline curves can be useful for constructing
smooth paths around a series of control points, as in exspline.c.
