org.mt4j.util.math.Matrix
Matrix defines and maintains a 4x4 matrix in row major order. This matrix is intended for use in a translation and rotational capacity. It provides convenience methods for creating the matrix from a multitude of sources. Matrices are stored assuming column vectors on the right, with the translation in the rightmost column. Element numbering is row,column, so m03 is the zeroth row, third column, which is the "x" translation part. This means that the implicit storage order is column major. However, the get() and set() functions on float arrays default to row major order! Copyright (c) JMonkeyEngine @author Mark Powell @author Joshua Slack @author C.Ruff
