Horizon science of graphical perspective. Assuming the picture plane stands vertical to ground, and "P" is the perpendicular projection of the eye point "O" on the picture plane, the horizon is defined as the horizontal line through "P". The point "P" is the vanishing point of lines perpendicular to the picture. If "S" is another point on the horizon, then it is the vanishing point for all lines parallel to "OS". But Brook Taylor (1719) indicated that the horizon plane determined by "O" and the horizon was like any other plane: The peculiar geometry of perspective where parallel lines converge in
Morris–Putnam point Morris–Putnam point The Morris–Putnam point (MPP or “Profit Horizon” ) is the point within a break even analysis where an algorithmic trend line indicates break even will be exceeded by n percent. Economists and Financial analysts use the Morris–Putnam point to predict the impact of commodities costs on juice and heavy metals profits. Meteorologists use "The Point" to forecast dew points and localized wind gusts. Sales people use the point to rationalize the addition of ‘fees’ to previously agreed upon prices because when modeled skillfully, the Morris–Putnam point almost always predicts future success. For example, if a citrus farm produces
