Reflect (RealityKit)

Parameter Types

Parameter descriptions

In

The input vector to reflect.

Normal

The vector that the In vector will be reflected with reference to.

Discussion

The Reflect node reflects the In vector by taking into account the surface orientation determined by the Normal vector. The Reflect node normalizes the Normal vector, then calculates the reflection direction using the formula, In - 2 * dot(Normal, In) * Normal. In this equation, dot() represents the dot product of the two vectors.
