-#include "SkTwoPointRadialGradient.h"
-
-/* Two-point radial gradients are specified by two circles, each with a center
- point and radius. The gradient can be considered to be a series of
- concentric circles, with the color interpolated from the start circle
- (at t=0) to the end circle (at t=1).
-
- For each point (x, y) in the span, we want to find the
- interpolated circle that intersects that point. The center
- of the desired circle (Cx, Cy) falls at some distance t
- along the line segment between the start point (Sx, Sy) and
- end point (Ex, Ey):
-
- Cx = (1 - t) * Sx + t * Ex (0 <= t <= 1)
- Cy = (1 - t) * Sy + t * Ey
-
- The radius of the desired circle (r) is also a linear interpolation t
- between the start and end radii (Sr and Er):
-
- r = (1 - t) * Sr + t * Er
-
- But
-
- (x - Cx)^2 + (y - Cy)^2 = r^2
-
- so
-
- (x - ((1 - t) * Sx + t * Ex))^2
- + (y - ((1 - t) * Sy + t * Ey))^2
- = ((1 - t) * Sr + t * Er)^2
-
- Solving for t yields
-
- [(Sx - Ex)^2 + (Sy - Ey)^2 - (Er - Sr)^2)] * t^2
- + [2 * (Sx - Ex)(x - Sx) + 2 * (Sy - Ey)(y - Sy) - 2 * (Er - Sr) * Sr] * t
- + [(x - Sx)^2 + (y - Sy)^2 - Sr^2] = 0
-
- To simplify, let Dx = Sx - Ex, Dy = Sy - Ey, Dr = Er - Sr, dx = x - Sx, dy = y - Sy
-
- [Dx^2 + Dy^2 - Dr^2)] * t^2
- + 2 * [Dx * dx + Dy * dy - Dr * Sr] * t
- + [dx^2 + dy^2 - Sr^2] = 0
-
- A quadratic in t. The two roots of the quadratic reflect the two
- possible circles on which the point may fall. Solving for t yields
- the gradient value to use.
-
- If a<0, the start circle is entirely contained in the
- end circle, and one of the roots will be <0 or >1 (off the line
- segment). If a>0, the start circle falls at least partially
- outside the end circle (or vice versa), and the gradient
- defines a "tube" where a point may be on one circle (on the
- inside of the tube) or the other (outside of the tube). We choose
- one arbitrarily.
-
- In order to keep the math to within the limits of fixed point,
- we divide the entire quadratic by Dr^2, and replace
- (x - Sx)/Dr with x' and (y - Sy)/Dr with y', giving
-
- [Dx^2 / Dr^2 + Dy^2 / Dr^2 - 1)] * t^2
- + 2 * [x' * Dx / Dr + y' * Dy / Dr - Sr / Dr] * t
- + [x'^2 + y'^2 - Sr^2/Dr^2] = 0
-
- (x' and y' are computed by appending the subtract and scale to the
- fDstToIndex matrix in the constructor).
-
- Since the 'A' component of the quadratic is independent of x' and y', it
- is precomputed in the constructor. Since the 'B' component is linear in
- x' and y', if x and y are linear in the span, 'B' can be computed
- incrementally with a simple delta (db below). If it is not (e.g.,
- a perspective projection), it must be computed in the loop.
