WebReflection works according the simple rule that "angle of incidence equals angle of reflection". Although there are no angles in the formula - all the necessary work is done by dot product. void Reflect (VEC3 &out, const VEC3 &incidentVec, const VEC3 &normal) { out = incidentVec - 2.f * Dot (incidentVec, normal) * normal; } Web29. apr 2013 · Reflect/Refract vector. Reflect and refract vector are derive from Snell ‘s law [4]: Reflect: float3 reflect( float3 i, float3 n ) { return i - 2.0 * n * dot(n, i); } Refract vector is calculated as: The derivation for refraction vector can be found in [4].

WebWith k x = component of the wave vector in x-direction = k = 2p/l, w = circular frequency = 2pn.: No index of refraction in the formulas; but we know (it is hoped), what to do. We must introduce the velocity v of the elecromagnetic wave in the material and use the relation between frequency, wavelength, and velocity to get rid of k or l, respectively. Web7. aug 2006 · Refraction at an interface is commonly described by n the refractive index and we can show that causality forces us to choose a negative sign for the refractive index when both ε and μ are negative. Conventionally we take n as given by and, where both ε and μ are positive, choose the positive sign for the square root. tina arena height and weight
