Finding the distance from a point to a line or from a line to a plane seems like a pretty abstract procedure. . But, if the lines represent pipes in a chemical plant or tubes in an oil refinery or roads at an intersection of highways, confirming that the distance between them meets specifications can be both important and awkward to measure. In Perspective Projection the center of projection is at finite distance from projection plane. A point A is situated in the first quadrant. Ellipsoidal Earth projected to a plane.

Projections of distant object are smaller than projections of objects of same size that are closer to projection plane. principles developed for projections of points. A sketch of a way to calculate the distance from point $\color{red}{P}$ (in red) to the plane. Recipes: orthogonal projection onto a line, orthogonal decomposition by solving a system of equations, orthogonal projection via a complicated matrix product. The distance between a plane and a point Q that is not on the plane can be found by projecting the vector P Q → onto the normal vector n (calculating the scalar projection p r o j n P Q →), we can find the distance D as shown below: D = ‖ P Q → ⋅ n → ‖ ‖ n → ‖ The distance formula can be reduced to a simpler form if the point is at the origin as: The side, opposite to the corner on which it rests is inclined at 30, A line CD, inclined at 25® to the HP,
