This is a column matrix, so operations like: <code>v1=A*B*C*v0</code>; applies C first , then B, then A to vector v0. <br> + Since it is a column matrix, the first column is the I vector of the base, 2nd is J, 3th is K. <br> + 4th column vector is T, the translation vector.<p> +Angle orientation are: Xaxis: YtoZ. Yaxis: ZtoX. Zaxis: XtoY.<p> +This matrix keep a matrix state to improve Matrix, vector and plane computing (matrix inversion, vector multiplication...). The internal matrix know if:<ul> +<li>matrix is identity</li><li>matrix has a translation component</li><li>matrix has a rotation component</li><li>matrix has a uniform scale component (scale which is the same along the 3 axis)</li><li>matrix has a non-uniform scale component</li><li>matrix has a projection component (4th line of the matrix is not 0 0 0 1).</li></ul> +<p> +An example of improvement is that CMatrix::operator*(const CVector &v) return v if the matrix is identity.<p> +By default, a matrix is identity.
