The 10 pages that link to Surface normal, each with the reason it gives.

• Cross productRelated: Crossing two tangent directions yields a normal to their plane.

• Snell's lawRelated: Incidence and refraction angles are measured from the interface's normal.

• Ray tracingRelated: Surface normals determine how rays reflect and refract at intersections.

• Specular reflectionBroader topic: Both angles in the reflection law are measured from this local direction.

• Surface integralRelated: The normal direction selects the component of a field that contributes to flux.

• Law of reflectionRelated: Both angles are measured from this reference line, not from the surface.

• Angle of incidenceRelated: The incidence angle is measured from this line at the point of contact.

• Cauchy stress tensorRelated: Its direction determines which traction the tensor returns.

• Lambert's cosine lawBroader topic: The law measures the angle between light or viewing direction and this reference direction.

• Meusnier's theoremRelated: It defines both the normal section and the curvature component used in the theorem.
