WebDec 4, 2024 · With the point (Swi, 0) known, the tangent equation can be expressed as: y = m (Sw — Swi), where, m is the slope of the tangent line, and Sw the water saturation. … WebMar 22, 2024 · Let P n, m be an endpoint then: V = P 1, 0 − P 0, 1. Doing this for two edges gives V a and V b. From this a tangent is calculated. Let T = the tangent then. T = V a − V b. It does this for both pairs of opposing edges given T a and T b. It uses the largest of the two as the result. It does something similar for Ngons.
