Webb19 juli 2015 · The OP used v → for the velocity of the ball and p → for the position of the center of the rectangle. Those two things do not determine the direction of the normal vector at all, so it is really unclear what you think you are doing with the formulas in this answer. – Jul 29, 2016 at 15:52 This would only be helpful in 3D – gen-ℤ ready to perish

The masking object can be any shape, color, or gradient, and it determines ... In geometry, a normal is an object such as a line, ray, or vector that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the (infinite) line perpendicular to the tangent line to the curve at the point. A normal vector may have length one (a unit vector) or its length may … Visa mer Calculating a surface normal 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.
