Conics - Translation
- Ryan Hirst
Notes: Coefficients A, B, C are unaffected by translation. If the starting coefficients are <A, B, C, D', E', F'>, and the conic is in the standard form The transformation vector is u = (Δx, Δy), And if the transformed coefficients are <A, B,C,D, E, F>, then the curve 1a can be written , The same procedure can be used to translate the curve. Leaving the coordinates in (x, y) --(local origin (0,0)) --, translates the curve by -u.
