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;
