How to calculate a normal vector
Web5 sep. 2024 · a ( x − x 0) + b ( y − y 0) + c ( z − z 0) = 0 And this is the equation representing the plane E because every point P ( x, y, z) on E satisfies this equation. This is why ( a, b, c) is the normal vector of the plane: a ( x − x 0) + b ( y − y 0) + c ( z − z 0) = 0. I hope this helps you know the reason behind this question better. Share Cite Follow WebCalculating a surface normal [ edit] For a convex polygon (such as a triangle ), a surface normal can be calculated as the vector cross product of two (non-parallel) edges of the polygon. For a plane given by the equation the vector is a normal. For a plane whose equation is given in parametric form
