Detailed Description

This class implements a 4x4 fpreal matrix in row-major order.

Most of Houdini operates with row vectors that are left-multiplied with matrices. e.g., z = v * M As a result, translation data is in row 3 of the matrix, rather than column 3.

This convention, combined with row-major order, is directly compatible with OpenGL matrix requirements.

Examples:

POP/POP_LocalForce.C, SIM/SIM_SolverSNOW.C, SOP/MSS_CustomBrushState.h, SOP/SOP_Flatten.C, and SOP/SOP_HDKObject.C.
