Detailed Description

GLSL compatible data types.

To simplify the use of MathFu template classes and make it possible to write code that looks similar to GLSL in C++, MathFu provides a set of data types that are similar in style to GLSL Vector and Matrix data types.

Typedef Documentation

typedef mathfu::Quaternion<float> mathfu::quat

Float-based quaternion. Note that this is not technically a GLES type, but is included for convenience.
