Compute the reflection color, compute the refraction color, and then apply the Fresnel equation. First we compute the reflection direction. For that we need two items: the normal at the point of intersection and the primary ray's direction. Once we obtain the reflection direction, we shoot a new ray in that direction.

Usually when you shot a ray toward a sphere you get 2 intersections, then you pick the nearest one and discard the other. If the surface is transmissive, you compute the refraction term and apply it to the ray.
Reflections and Refractions in Ray Tracing

It does not matter which refractive index is the greatest. All that counts is that η 1 is the refractive index of the material you come from, and η 2 of the material you go to. This(very important) concept is sometimes misun-derstood. The direction vector of the incident ray (= incoming ray) is i, and we assume this vector is normalized. The ...

Both reflection and refraction directions are based on the normal at point of intersection and the direction of the incoming ray (the primary ray). To compute the refraction direction we also need to specify the index of refraction of the material.

Ray-Surface Intersection Routines. As shown in the pseudo-code above, one of the main aspects of the Ray Tracing algorithm is the ability to test for the intersection of a primitive and a ray. A primitive is any object that exists in the world. Simple examples of primitives include spheres and polygons. A collection of polygons are usually ...

The reflected and refraction ray are then computed (lines 22 and 27) and the reflected and transmitted light is computed by tracing a ray in both the reflected and refracted direction. Note that we have to add a small bias again to the ray origin to avoid the phenomenon of acne which we already described in the chapters on shadows.
