Intro

Vector mathematics for computer graphics

Features

• basic arithmetic operations - using operators
• basic linear algebra operations - such as transpose, dot product, etc.

• aliases for vertex coordinates - it means:

   Vector3f v;
   // use vertex coordinates
   v.x = 1; v.y = 2; v.z = -1;

   // use texture coordinates
   v.s = 0; v.t = 1; v.u = 0.5;
   // use color coordinates
   v.r = 1; v.g = 0.5; v.b = 0;
     

• conversion constructor and assign operators - so you can assign a value of Vector3<T1> type to a variable of Vector3<T2> type for any convertible T1, T2 type pairs. In other words, you can do this:

   Vector3f f3; Vector3d d3 = f3;
   ...
   f3 = d3;
