using Eigen


Today I took some time to replace my own (vector) math library by Eigen.
This library is great and fast. I could replace my own lib in my software (3d opengl and math calculation) in few hours only.
(I still use the "double" type because it provides better precision and I didn't see any speed improvement using float)

PS: if you see a linkage issue with Eigen and you are using cross or dot, then just include the geometry header: #include <Eigen/Geometry>

Hope it will be useful for you.

Happy coding.
