WebJun 28, 2024 · Projecting points onto a line: Point (x1, y1) and vector [vecX, vecY] y = mx + c. m = vecY vecX. Point on vector (0, 0) . So axis line: y = vecY vecX ∗ x. Perpendicular m ′ = − vecX vecY. So the perpendicular line that crosses (x1, y1) y = m ′ x + c ′ y1 = − vecX vecY … WebProjection of a point on a line in 2D or 3D space This formula calculates the orthogonal projection of a point M on a Line L passing through point A and directed by vector →u u → .

WebLet P be a vector, and π ( P) its normal projection onto the plane. Then, P − π ( P) = D n for some D ∈ R. Keeping in mind that n is orthogonal to the plane, we can write D = ( P − π ( P)) ⋅ n = ( P − π ( P)) ⋅ n + ( π ( P) − Q 1) ⋅ n = ( P − Q 1) ⋅ n Finally, we have: π ( P) = P − ( ( P − Q 1) ⋅ n) n Share Cite Follow edited Jul 16, 2013 at 13:48
