Detailed Description

3x3-Matrix operations.

Some operations for matrices. Re-Volt uses a 3x3-float-array, where the matrix is encoded as column vectors.

This class is directly written to and read from files.

It may only contain the three coordinates, and nothing more that requires storage memory, like virtual functions.
