static inline void t8_normal_of_tri(const TVecP1 &p1, const TVecP2 &p2, const TVecP3 &p3, TVecNormal &normal)

Compute the normal of a triangle given by its three vertices.

Parameters:

• p1 – [in] A 3D vector.

• p2 – [in] A 3D vector.

• p3 – [in] A 3D vector.

• normal – [out] vector of the triangle. (Not necessarily of length 1!)d
