#include <matrix.h>
Matrix.
The matrix has a dimension of 4×4 and consists of four rows and four columns. The first row is always "1, 0, 0, 0" and not stored in the class, which means that there are 12 actual numbers used. These numbers are grouped into four vectors, one for the remaining numbers in each column. The four vectors are called off, v1, v2 and v3, together these four vectors can be used to represent the coordinate system. A coordinate system consists of three axes, one for each coordinate (X, Y and Z). The system also has a base position, from which the three axes originate. This base position is stored in off, and the three axis vectors are stored in v1, v2 and v3 respectively. For a rectangular, normalized matrix v3 equals the cross product of v1 and v2 (v1v2). C4D by default uses a left-handed coordinate system (see define COORDINATESYSTEM_LEFT_HANDED).
