Detailed Description

Matrix specification.

It is stored internally as a 4x4 array of floats

Member Function Documentation

void multLineMatrix (  const Line &  src, Line &  dst )  const

Multiplies the given line by the matrix resulting in a new line. The origin of the line is transformed by the whole matrix. The translation part of the matrix is ignored when transforming the direction of the line.
