Vec4_< T > Class Template Reference

Detailed Description

template<class T>
class asl::Vec4_< T >

A Vec4 is a 4-dimensional vector usually representing homogenous coordinates.

It can be used together with class Matrix4 to transform vectors in projective space.

Vec4 a (10, 10, 0.1, 1.0);
Vec3 v = a.h2c();

#include <Vec4.h>
