Matrix The matrices in Nebula are Row Major which is identical to D3D. This means that a matrix position of [1][2] means we are refering to the number in [Row 1][Column 2]. The following is the layout of the rows and columns in the Nebula matrix44 matrix. | M11 M12 M13 M14 | | M21 M22 M23 M24 | | M31 M32 M33 M34 | | M41 M42 M43 M44 | Note: You can get the element of the matrix by the macro Mrc. r indicates the row of the element and c indicates the column of element. For an example, you can get the first element of the matrix by m.M11('m' is the instance of the matrix44 or matrix33 class). matrix44 provides its member functions to access each of the rows. The first row can be accessed by matrix44::x_component(). And there're matrix44::y_component() and matrix44::z_component() for the second and third row. The member function which access to the 4th row is matrix44::pos_component().
