get-medial-point-coeffs-bez0

function getMedialPointCoeffsBez0(p: number[], v: number[], P: number[]): { a0: number; b0: number; }

Defined in get-medial-points/double/get-medial-point-coeffs-bez0.ts:17

Returns the coefficients a0 and b0 for the linear equation a0⋅t + b0 = 0, so the ray parameter can be recovered as t = -b0/a0. That parameter value makes q(t) = p + t⋅v equidistant from p and P.

Let p be a fixed point in the plane.
Let v be a direction vector defining the ray q(t) = p + t⋅v.
Let P be another point.\

In other words, this function returns the coefficients needed to solve for the ray parameter of the medial point on the ray.

Parameters:

Name	Type	Description
p	number[]	base point
v	number[]	ray direction from p
P	number[]	another "target" point, e.g. [1,2]
