GTX Extensions (Experimental)

Compute the normal of a triangle. More...

## Functions
template<typename T >
detail::tvec3< T > | triangleNormal (detail::tvec3< T > const &p1, detail::tvec3< T > const &p2, detail::tvec3< T > const &p3)
| Computes triangle normal from triangle points.

## Detailed Description

Compute the normal of a triangle.

<glm/gtx/normal.hpp> need to be included to use these functionalities.
