Function Documentation#

template<u32 L, typename T>
constexpr Vec<L, T> TRAP::Math::Reflect(const Vec<L, T> &I, const Vec<L, T> &N)#

Calculate the reflection direction for an incident vector.

Parameters:

  • I – Specifies the incident vector.

  • N – Specifies the normal vector.

Returns:

For the incident vector I and surface orientation N, returns the reflection direction: result = I - 2.0 * Dot(N, I) * N.
